Underwater welding work expands at TWI North

The increasing variety of underwater projects in TWI North's unique tank facility included a survey of commercially available underwater welding consumables.

The project was carried out in a depth of 6.5m on 8mm thick plate in vertical down and overhead positions. Rigorous testing simulated welding required in repair of offshore structures, ship repair or harbour sheet pile work. The welding and evaluation of electrode handleability was carried out by qualified experienced welder divers.

TWI North are running an underwater welder training programme, which conforms to the American Welding Society Standard AWS D3.6 weld class B coding.

Eligibility criteria would be that all students have a commercial diving background and basic knowledge of welding procedures.
