Coded welding

Complete Coded Welding Solutions

With over 45 years of experience, WEC Fabrication provides a complete coded welding service from state-of-the-art facilities. Our 200 certified welders are skilled in MIG, TIG, MMA and SUB-ARC, applying multi-coded procedures across most projects. Together they hold more than 600 codings and bring over 6,000 years of combined experience. Guided by two CSWIP-certified instructors, our team delivers the highest standards and welds complex structures that others cannot.

Coded Welding

At WEC Fabrication, we provide specialist coded welding services to support a wide range of industries, including oil & gas, nuclear, structural steelwork, and general metal fabrication. Our welders are fully qualified in multi-coded MIG, TIG and SUB-ARC techniques, with all welding procedures assessed and approved by PED-accredited bodies. We maintain an extensive in-house stock of materials including mild steel, stainless steel, aluminium and duplex in various grades, enabling fast response times and flexibility for time-sensitive projects.

Every weld is completed to exacting standards, with fabrications manufactured in line with ASME and BS EN specifications. This ensures full compliance with international codes and guarantees the structural integrity of each fabrication. Whether you require a one-off coded welding solution or ongoing support for large-scale fabrication, WEC Group offers the expertise and capacity to deliver.

Our welding teams are qualified to:

• ISO 9606-1
• BS 15614-1
• ASME equivalents
• BS EN 1090-2
• ISO 3834
• AWS D1.1

CSWIP-Certified Excellence

At WEC Fabrication, quality begins with some of the most skilled welding professionals in the UK, including one of only a few CSWIP Master Welding Engineers in England supported by CSWIP-certified inspectors. This rare expertise ensures every weld meets internationally recognised standards and delivers the highest levels of oversight and quality assurance. We train and upskill our own welders, with every apprentice becoming a coded welder after their first year. With full in-house capability to test and certify our team, we can quickly achieve any client-required accreditation from advanced coding to bespoke procedures.
