AS/NZS 1796 purpose

It sets requirements for qualification and certification of welding supervisors, inspectors and coordinators, so that welding in Australia and New Zealand is controlled by personnel with verified competence.

Who certifies welding supervisors

A recognised independent certification body assesses the candidate and issues the certificate; the employer cannot self-issue certification, though the employer verifies experience and employment history.

Competency-based certification

Certification requires both a knowledge examination and documented practical welding-related experience, rather than experience alone or a qualification test piece alone.

Supervisor core duty

The certified supervisor verifies that production welding follows an approved WPS, uses qualified welders within their qualified range, and that records are completed and retained.

Welding Procedure Specification

A WPS is a written, qualified document specifying joint preparation, process, consumables, parameters and technique, which the supervisor must confirm is available and current at the workface.

Procedure qualification record

The record of the test assembly and mechanical results that supports a WPS; the supervisor checks it exists and covers the production thickness, material group and process.

Welder qualification range

A welder's qualification is limited by process, position, joint type, consumable group and thickness; the supervisor confirms these limits cover the production joint before welding begins.

Certification levels and authority

Different certification levels carry different scopes of supervisory authority and document countersigning rights; the holder must work only within the scope of the level held.

Renewal of certification

Certification is time-limited and renewed on evidence of continuing welding supervision practice plus current knowledge; a lapsed certificate removes authority to supervise certified work.

Supervisor record set

Typical records include WPS, procedure qualification records, welder certificates, consumable certificates, inspection and test reports, and non-conformance reports, all controlled and retrievable.

Welding metallurgy knowledge

Supervisors must understand how heat input, cooling rate, preheat and hydrogen affect microstructure and cracking, so they can judge whether parameters and controls are appropriate.

Consumable control duty

The supervisor ensures consumables are stored, dried and issued per manufacturer requirements, and that electrode or flux condition does not compromise the qualified procedure.

Preheat verification

Where the WPS specifies preheat or interpass limits, the supervisor confirms measurement with suitable equipment and records the values before and during welding.

Inspector versus supervisor

The inspector performs and reports inspection and testing against criteria; the supervisor organises and controls the welding activity, including ensuring inspection occurs at required hold points.

Hold and witness points

Hold points require inspection sign-off before work proceeds; witness points require notification and the opportunity to observe. The supervisor enforces them in the inspection plan.

Unqualified welder action

If a welder's qualification does not cover the joint, the supervisor stops the work, arranges qualification or reassignment, and records the action taken.

Welding coordination definition

Welding coordination is the assigned organisational function that integrates contract review, design, purchasing, production and inspection so welding quality requirements are met consistently.

Designated welding coordinator

A named person with defined authority and competence is responsible for coordinating welding activities; the role and its limits are documented in the quality management system.

Quality management system

A documented system of procedures, responsibilities and records that plans, controls, verifies and improves welding quality in a repeatable, auditable way.

Plan-do-check-act

Quality objectives are planned, work is executed to qualified procedures, results are checked by inspection and testing, and deviations drive corrective action and improvement.

Document control rule

Only the current revision of WPS, qualification records and inspection plans may be used at the workface; superseded copies are withdrawn and clearly marked.

Material traceability

Heat or batch identification of base metal and consumables is recorded against the joint, so failures can be traced to material certificates and the procedure used.

Non-conformance steps

Identify and record the nonconformity, segregate or mark the item, decide disposition (rework, repair, concession or reject), verify the disposition, then close the record.

Concession or deviation

Acceptance of nonconforming work requires documented approval from the customer or design authority before release, and the item must still be fit for purpose.

Corrective action

Action removes the cause of a detected nonconformity, not just the symptom; effectiveness is verified and the change is reflected in procedures and training.

Skills matrix

A register listing each welder's qualified processes, positions, materials and expiry dates, used to plan requalification and prevent assignment outside qualification.

Calibration requirement

Measuring, testing and monitoring equipment used for acceptance decisions must be calibrated against traceable standards, with calibration records retained and status identified.

Internal audit purpose

Internal audits verify that welding activities conform to the quality plan and standard; findings feed corrective action and management review.

Management review inputs

Review considers audit results, defect and repair trends, customer feedback, nonconformance data and resource needs, and outputs decisions and actions for improvement.

Purchasing controls

Base metal and consumable purchases specify required standards and certificates; incoming verification confirms grade, condition and documentation before release to production.

Subcontractor welding control

Subcontracted welding is controlled by the same requirements: approved procedures, qualified welders, specified records and verification before acceptance of the work.

Inspection and test plan

The plan lists operations, inspection stages, acceptance criteria, hold and witness points, and record requirements, forming the basis for verifying welding quality.

Repair welding control

Repairs use a qualified procedure and qualified welders, are recorded with location and extent, and are inspected to the same acceptance criteria as the original weld.

Record retention

Welding records are kept for a defined period to allow later verification of procedure, personnel and material; retention time is stated in the quality system.
