Joining processes — Quality assurance

Introduction

Joining processes — Quality assurance is a vocational learning module for blacksmithing and artistic metalwork. It focuses on how you plan, control, inspect, measure, record and improve joined metalwork so that the finished item meets the drawing, sample, client brief, conservation specification and workplace quality requirements.

Selected jurisdiction: United Kingdom. To avoid blending different systems, this course uses Great Britain rules and Health and Safety Executive guidance for workplace safety, and it labels the England apprenticeship route separately for vocational training. Northern Ireland has separate health and safety legislation and training arrangements and is not covered here. British Standards are discussed only where they are relevant to a job specification. This course does not claim automatic equivalence with any other country.

Official rules, the current risk assessment, hot-work permit, manufacturer instructions, welding procedure, drawing, project specification and workplace instructions take precedence over this learning material. Hazardous joining work must not be practised unsupervised.

Learning Outcomes

By the end of this module, you should be able to explain the difference between quality assurance and quality control, identify quality requirements before joining begins, recognise common visible imperfections and process errors, select basic inspection and measuring tools, record traceable results, respond correctly to non-conforming work, explain why visual inspection has limits, and relate quality decisions to safety, sustainability, function and artistic intent.

Great Britain Workplace Safety Duties

The Health and Safety at Work etc. Act 1974 provides the broad legal framework in Great Britain. Joining work is also affected by more specific duties, including the COSHH framework for hazardous substances such as welding fume, the PUWER framework for work equipment, and the Personal Protective Equipment at Work Regulations 1992 as amended in 2022.

HSE states that all welding fume can cause lung cancer and that exposure must be controlled even when the amount of welding is small. Control starts by avoiding or reducing exposure, then using suitable engineering controls such as local exhaust ventilation where appropriate, with suitable respiratory protective equipment when required by the assessment. General ventilation alone is not a substitute for effective source control in routine indoor welding.

HSE also requires work equipment to be suitable, maintained in a safe condition and used by people who have received adequate information, instruction and training. PPE is not the first control: hazards should be eliminated or controlled by safer processes, engineering measures and safe systems of work before relying on PPE.

Hot work can ignite combustible materials well beyond the immediate joint. HSE guidance requires fire and explosion risk to be assessed and controlled. Work on drums, tanks or containers that contain or have contained flammable or combustible substances is especially dangerous and must not be treated as an ordinary workshop exercise. If acetylene is used, separate requirements and competent controls apply.

Safety video guide: This welding-fume video from the HSE “Go Home Healthy” campaign is useful for discussing control at source. Your own workplace assessment and current HSE guidance remain authoritative.

England Vocational Training Pathway

Skills England lists the Blacksmith apprenticeship ST0378, version 1.1 as approved for delivery at Level 3, with a typical duration of 48 months and Ofqual named as the external quality assurance provider. Its occupational profile covers designing, shaping and joining metal components by hot forging and other metalworking processes for bespoke, small-batch and heritage metalwork. The standard includes thermal welding and cutting, hot forging, fitting, quality, safe working, equipment and materials.

The apprenticeship is a broad occupational programme. It does not mean that a learner is automatically qualified for every coded weld, every welding process, every material or every regulated product. Project-specific welder qualification, procedure qualification or third-party certification may be separately required.

British Standards Relevant to Welding Quality

Standards are not interchangeable with legislation. They become practically important when they are required by a contract, product standard, execution specification, employer quality system, client requirement or other binding document.

Standard	Practical relevance	Important boundary
BS EN ISO 17637:2016	Visual testing of fusion-welded joints in metallic materials	Visual testing does not establish acceptance limits by itself; the applicable product or application standard must define the extent and criteria
BS EN ISO 5817:2023	Quality levels B, C and D for imperfections in specified fusion-welded joints	Do not choose a quality level by guesswork and do not apply it automatically to forge welds, brazed joints or rivets
BS EN ISO 3834-2:2021	Comprehensive quality requirements for fusion welding in workshops and on installation sites	Intended for organisations that need a structured welding-quality system
BS EN ISO 15609-1:2019	Content of welding procedure specifications for arc welding	A WPS is a controlled process document, not a personal tip sheet
BS EN ISO 9606-1:2017	Qualification testing of welders for fusion welding of steels	Qualification has a defined scope and is not a universal licence to weld

Core Concepts of Quality Assurance

Quality Assurance and Quality Control

Quality assurance, QA, is the planned system that helps prevent defects and variation. It includes clear requirements, competent people, suitable materials, controlled procedures, maintained equipment, traceability, inspection stages, records and corrective action.

Quality control, QC, is the checking of actual work against requirements. It includes visual inspection, dimensional measurement, non-destructive testing where specified, functional checks and recording whether the item passes, requires authorised repair or must be rejected.

A useful workshop sequence is:

Requirement → Plan → Prepare → Join → Inspect → Measure → Record → Accept / repair / reject → Learn and improve

Quality is not the same as making a weld look smooth. A visually neat joint can contain internal lack of fusion, and an artistically textured joint can still be fit for purpose if it meets the agreed design, structural and conservation requirements.

Acceptance Criteria Must Exist Before Inspection

Before you join metal, identify what will make the joint acceptable. Depending on the work, that may include a drawing, sample, client brief, heritage conservation specification, WPS, inspection and test plan, employer quality procedure, dimensional tolerance, surface-finish requirement, or a specified quality level in a standard.

Do not invent acceptance limits after seeing the finished work. If a requirement is unclear, stop and ask the responsible supervisor, designer, welding coordinator or client representative before proceeding.

Process Control and Traceability

A repeatable joint depends on controlling the variables that matter. For fusion welding these may include joint preparation, material identity, consumable, position, shielding, cleanliness, equipment condition and the approved procedure. For forge welding they may include compatible stock, clean faying surfaces, scarf form, fire or furnace condition, controlled heat and hammering sequence. For riveting they include hole preparation, rivet size and material, heat condition where hot riveting is specified, set and head form.

Traceability means being able to connect the finished joint with the relevant job information. In a small artistic workshop this may be a job card, sketch, material note and inspection record. In more controlled fabrication it may include material certificates, welder identification, WPS number, batch data, inspection reports and non-conformance records.

Joining Processes in Blacksmithing and Artistic Metalwork

Forge Welding

Forge welding is a solid-state or near-solid-state joining method in which prepared metal surfaces are brought together at a suitable high forging temperature and consolidated by pressure or hammering. In traditional and contemporary blacksmithing it can preserve the visual language of forged work and avoid a deposited arc-weld bead.

Quality assurance begins before the weld: compatible material, clean interfaces, appropriate scarf geometry, controlled heating, correct alignment and a planned sequence. Common warning signs include an open seam, cold shut, scale trapped at the interface, visible delamination, excessive thinning, burned material, misalignment and distortion.

Image guide: A traditional forge provides heat, fuel and air. For QA, observe that fire management is a process variable. The photograph is not a safety model; your workshop controls, ventilation, fuel handling procedures and instructor directions govern practice.

Arc Welding Used in the Forge and Fabrication Shop

In UK workshops, you will commonly hear MIG used as a general shop term, but when an active shielding gas is used on steel the process is technically MAG. You may also encounter TIG, MMA or flux-cored processes. Quality assurance requires you to use the process terminology, procedure and consumables that match the job documentation.

Diagram guide: The GMAW diagram shows the direction of travel, contact tube, electrode wire, shielding gas, molten weld pool, solidified weld metal and workpiece. During QA, each part of this process can affect the finished joint. You inspect the outcome, but you also control the process that created it.

Image guide: A visible arc and weld pool are only part of the system. Fume control, shielding, joint preparation, equipment condition and the approved procedure are all quality and safety concerns.

Brazing and Soldering

Brazing joins metals with a filler metal that melts below the parent metal. Quality depends on correct joint clearance for the process, clean surfaces, suitable filler and flux where required, controlled heating and complete wetting or flow through the intended joint. Flux residue may need removal because it can affect appearance or corrosion performance.

Do not use a torch or heat source without the training, fire controls, ventilation and supervision required by the workplace. Material coatings can create hazardous fumes when heated.

Riveting, Bolting and Mechanical Fastening

Mechanical joining is important in architectural and heritage ironwork. It may be chosen for authenticity, repairability, disassembly or to avoid heat effects. QA checks include correct fastener material and size, hole quality, alignment, seating, head form, clamp or preload where specified, locking method, surface protection and the absence of cracks or damaging distortion.

A decorative rivet head is not automatically a sound joint. It still has to meet the load, geometry and conservation requirements of the job.

Tools, Materials and Records

Inspection and Measuring Tools

Typical tools include a steel rule, tape, engineer's square, straightedge, vernier or digital caliper, feeler gauges, radius gauges where relevant, fillet weld gauge where specified, adequate task lighting, inspection mirror, magnifier, marker, camera or tablet, and the current drawing or job card.

Image guide: This Wikimedia Commons photograph shows a weld gauge. A gauge is only useful when you know which feature to measure, how to position it, and which drawing or acceptance criterion controls the result.

Inspection tools must be suitable for the required accuracy. Where calibration or verification is required by the quality system, check the tool status before use. A damaged gauge or an out-of-date controlled drawing can create a false pass.

Joining Equipment and Consumables

Quality-relevant equipment can include forge or furnace, anvils and swages, tongs, jigs and fixtures, welding power source, wire feeder, torch or electrode holder, earth return, gas delivery equipment, extraction, grinders and cleaning tools. Consumables can include welding wire or electrodes, shielding gases, brazing filler, fluxes, rivets, bolts, cleaning products and surface-protection materials.

Select materials and consumables from the drawing, procedure or approved job specification. Do not substitute a different grade, filler, flux, gas or fastener simply because it is available.

Quality Records

A useful small-workshop QA record can include job reference, component identity, material, joining process, procedure or approved method, operator, inspection stage, measured features, observed imperfections, result, authorised repair action and sign-off.

If the job uses a formal non-conformance system, record the issue rather than hiding it. Rework must be authorised and controlled because repeated heating, grinding or welding can change section size, metallurgical condition, distortion and appearance.

Risk Controls for Quality Work

Good quality and safe work support each other. Rush, poor housekeeping, defective equipment, inadequate extraction and unclear instructions can create both defects and injuries.

Hazard	Quality link	Control principle
Welding fume and gases	Poor extraction position can affect work access and expose others	Avoid or reduce welding where possible; use effective LEV and suitable RPE as required by the HSE risk assessment
Fire and hot metal	Uncontrolled sparks or delayed ignition can damage the work and premises	Clear combustibles, use the workplace hot-work system and maintain the required fire watch
UV and optical radiation	Poor visibility encourages incorrect technique	Use correctly selected eye and face protection and screens for others
Grinding and cutting	Excessive dressing can reduce section or hide evidence of poor joining	Use guarded, suitable equipment and remove only what the specification permits
Compressed gases	Incorrect gas or unstable supply can affect the process	Use approved equipment, secure cylinders, follow manufacturer and workplace instructions, and keep incompatible gases correctly separated
Noise and vibration	Fatigue reduces concentration and inspection accuracy	Apply workplace controls, exposure management and suitable PPE where required
Manual handling	Forced posture can disturb fit-up and cause injury	Use supports, jigs, lifting aids and team handling as planned
Hot forge scale	Scale at a joining interface can reduce forge-weld quality	Control fire, surface preparation and safe handling under instructor supervision

Stop-work rule for learners: if the process, material, drawing, extraction, guard, gas equipment, PPE/RPE, fire control or supervision is not as required, stop and tell the responsible person. Do not improvise a hazardous workaround.

Step-by-Step Demonstration

Instructor-Led QA Demonstration: MAG Fillet-Welded Mild-Steel Practice Joint

This demonstration is designed to teach quality assurance around joining, not independent welding. A learner must not energise welding equipment, perform hot work, handle compressed-gas equipment or grind a weld unless trained, authorised and directly supervised. The instructor must use the current workplace risk assessment, WPS or approved practice specification, fume controls and PPE/RPE requirements.

Read the requirement: Review the drawing or practice sheet, required joint type, dimensions, finish, WPS or approved method, inspection stage and acceptance criteria before touching the work.
Confirm identity and condition: Check the parent material, consumable identification, surface condition and relevant equipment status. Quarantine anything that is doubtful.
Check the work area: Confirm extraction, screens, fire controls, housekeeping, electrical leads, return connection, guarding and supervision. Do not proceed if any control is missing.
Inspect fit-up: Check joint orientation, contact or root condition as specified, squareness, tack location and restraint. Record the starting dimensions where distortion matters.
Join under direct supervision: The authorised operator follows the approved procedure. The learner observes how torch position, travel, shielding, heat input and sequence are controlled rather than choosing settings by guesswork.
Allow safe cooling and cleaning: Follow the workplace method. Do not touch, quench, grind or dress the joint unless the approved method permits it.
Perform visual inspection: Under suitable lighting, inspect the full weld length, toes, starts and stops, crater area and adjacent parent metal. Look for cracks, overlap, undercut, visible porosity, arc strikes, spatter where it matters, poor profile and incomplete coverage.
Measure: Use the specified gauge or measuring tool to check weld size, length, position, alignment, overall dimensions and distortion against the drawing or acceptance criteria.
Record the result: Mark pass, authorised repair or reject only against the stated criteria. Photograph the joint if the workplace system permits and record the operator and procedure reference.
Close the feedback loop: If there is a non-conformity, identify the likely process cause with the supervisor and agree corrective action. Do not simply grind away the evidence or add weld metal without authorisation.

Diagram guide: This Commons diagram illustrates weld discontinuities. Use it to practise describing what you see. Whether an imperfection is acceptable depends on the applicable specification and its limits.

Diagram guide: Cracks can occur in different locations and directions. A crack is a serious finding that must be referred to the responsible person; do not attempt an unapproved cosmetic repair.

Video guide: TWI's introduction to non-destructive testing shows several NDT methods. In real production, specialist methods must be carried out by competent personnel to an approved procedure. Radiography involves ionising radiation and is not a learner workshop activity.

Common Errors and What They Teach

Common error	Why it matters	QA response
Inspecting only after everything is finished	Fit-up, material and process errors may already be locked in	Use hold points before, during and after joining
Calling every gas-shielded wire process MIG	The terminology can hide a mismatch between gas, process and procedure	Use the process designation on the WPS or job documentation
Grinding every weld flush	It can remove required throat or leg size, hide evidence and waste time	Dress only where the drawing or finish specification requires it
Judging by appearance alone	Internal imperfections may not be visible	Use the specified inspection method and understand its limits
Measuring with an unsuitable tool	A precise-looking number may still be wrong	Match the tool, calibration status and technique to the tolerance
Repairing without authorisation	Repeated heat cycles or grinding can make the component worse	Raise the non-conformance and follow the approved repair route
Treating a heritage repair like new fabrication	Original material, tool marks and historic evidence can be lost	Follow the conservation specification and use minimum necessary intervention
Recording only successful work	The shop loses evidence needed for improvement	Record defects, causes and corrective actions as part of normal professional practice

Quality Criteria by Joining Process

Joining process	Typical criteria	Important limitation
Forge weld	Closed sound-looking seam, alignment, required section, smooth forged transition where intended, no obvious delamination or burned material, correct historic or artistic character	Visual appearance cannot prove complete internal bonding; acceptance comes from the drawing, sample, conservation brief and any specified tests
MAG, MIG, TIG or MMA fusion weld	Correct location, size, length, profile, continuity, dimensional accuracy, controlled distortion and imperfection limits from the specified acceptance document	BS EN ISO 5817 quality levels apply only where the job specifies them and within the standard's scope
Brazed joint	Correct location, evidence of wetting and filler flow, clean finish, dimensions, no damaging overheating or unacceptable residue	Acceptance depends on the joint design, process specification and service requirements
Riveted joint	Correct rivet, seating, head form, alignment, tightness, no cracking, no unacceptable damage to surrounding forged work	Decorative symmetry does not replace structural or conservation requirements
Bolted or screwed joint	Correct grade and finish, washer or locking arrangement where specified, alignment and tightening method	Torque or preload must come from the job requirement, not a generic value

Visual Inspection and NDT

Visual inspection is usually the first inspection method because it is fast, inexpensive and can be applied before, during and after joining. It can identify many surface imperfections and dimensional problems. It cannot reliably reveal every internal discontinuity.

BS EN ISO 17637:2016 provides a framework for visual testing of fusion-welded joints. Other NDT methods include magnetic particle testing for suitable ferromagnetic materials, penetrant testing for surface-breaking discontinuities, ultrasonic testing and radiographic testing. Method selection depends on the material, joint geometry, likely flaw type, access, acceptance standard and required competence.

Do not treat NDT as a do-it-yourself extension activity. Penetrant and magnetic-particle consumables require chemical controls, ultrasonic inspection requires trained interpretation, and radiography requires specialist radiation controls.

Authentic Workshop Examples

Example: Forged Garden Gate

A gate may combine forged tenons, collars, rivets and MAG welds. QA starts with the setting-out dimensions. The shop checks stile and rail alignment, repeatability of scrolls, fit of forged elements, weld or rivet quality, gate squareness, hinge position, distortion and the final finish. A weld that passes its local visual check can still be unacceptable if the gate has twisted and will not fit the opening.

Example: Heritage Railing Repair

A conservation repair may require retaining as much original wrought or mild steel as possible. The quality criteria can include matching historic section, forge texture, tool marks and fixing details as well as structural function. A modern visible weld bead or aggressive grinding may be unacceptable even when mechanically sound. The conservation specification and responsible heritage professional control the decision.

Example: Sculptural Mild-Steel Frame

For an indoor sculpture, the designer may require visually clean transitions and tight dimensional control so panels align. A jig, planned weld sequence and early checks can prevent cumulative distortion. The QA record may include a reference photograph and measured datums before surface finishing hides the joints.

Sustainability and Resource Efficiency

Quality assurance reduces rework, scrap, unnecessary grinding, repeat heating and wasted consumables. For a blacksmithing or artistic-metalwork workshop, good sustainability practice includes planning stock sizes before cutting, nesting parts efficiently, reusing suitable offcuts, choosing repair over replacement when it is technically and ethically appropriate, avoiding over-welding, maintaining equipment for efficient operation, segregating recyclable metals, and controlling hazardous residues from coatings, fluxes, cleaning products and filters.

Heritage work adds another sustainability principle: retain useful original material when the conservation brief allows it. Preserving an existing component can conserve both embodied energy and cultural value.

Do not compromise safety or required joint performance to save material or energy. A failed joint creates more waste than a correctly specified process.

Reflection

Think about one joined object you have made, repaired or inspected. Separate what you judged by appearance from what you actually measured or verified. Consider which requirement should have been written down before work started, which process variable had the greatest effect on quality, and what evidence would allow another craftsperson to repeat or audit your decision.
