Coded welder and boilermaker visas
Coded welders and pressure boilermakers brought into Australian shutdowns or fabrication campaigns generally come in on a Subclass 400 Temporary Work (Short Stay Specialist) visa where the work runs to a defined end date. The strength of the application rests on the welding procedure qualification, which is objective, documented, and precisely the kind of evidence a 400 case needs. Resource Visa prepares these applications for Australian employers and fabrication contractors.
What the role covers on Australian sites
Welding on pressure equipment, pipework, structural steel and specialised alloys, qualified to a specific welding procedure specification and a recognised code. “Coded” means qualified to a procedure — position, process, material, thickness range and consumable — not simply that the person can weld.
Boilermakers and pressure welders are concentrated in shutdown work, where the welding is on plant that has to go back into service under an integrity regime.
What the application has to evidence
The welder qualification record and the procedure it sits against. Which code — AS/NZS, ASME IX, ISO 9606 — and which materials and positions. Where exotic alloys, dissimilar metals or difficult positions are involved, say so, because that is where the available pool narrows sharply.
The specialised-skills argument here writes itself when the coding is specified and is weak when it is not. “Welder” is a trade. “Welder qualified to ASME IX on duplex stainless in the 6G position” is a specialist.
Certification and licensing — the clock nobody counts
The trap on this role. Welder qualifications are procedure-specific and often need to be verified, and in many cases requalified, against the procedure being used on the Australian job. An overseas coding does not automatically transfer to your WPS.
Requalification takes time and a test facility. It runs after arrival unless someone plans it, which means a welder can land in Australia legally and still be unable to start.
Confirm what your fabrication or integrity team actually requires before the welder is engaged.
What usually goes wrong
Coding assumed to transfer. The single most common problem on this role, and it is discovered on site.
Described as a trade rather than a coding. Weakens the application unnecessarily.
Requalification not scheduled. The visa is not the last constraint.
Frequently asked questions
For a defined campaign of up to three months, generally a Subclass 400, which requires no sponsorship.
Not automatically. Welder qualifications are procedure-specific and frequently require verification or requalification against the procedure in use on the Australian job. Confirm with your integrity or fabrication team before engagement.
Substantially. The procedure, code, materials and positions are what convert “welder” into a documented specialist skill.
Each welder needs their own application, but the business case is shared and the work runs as a batch.
