Weld Procedure Development
Custom welding procedures (WPS) development and qualification to AS/NZS, ASME and ISO standards.
Overview
Weld procedures are the foundation of compliant, high-integrity welding. MW John Welding Services assists with developing and qualifying Welding Procedure Specifications (WPS) to meet AS/NZS, ISO and ASME code requirements.
We work across a wide range of materials – including carbon, stainless, duplex, and exotic alloys – to produce project-specific procedures that address essential variables, material compatibility, and joint performance.
Finalised procedures are documented in full and can be tested and qualified under our supervision, ready for client or QA submission.
This service is ideal for fabricators and contractors needing third-party support for documentation, testing, and pre-production planning.
