Qualified welders, accepted on site
A welder may only work on code jobs when the qualification matches the process, material, thickness and position of the weld. We organise the test, witness the welding, have the coupons examined, and issue the record your client or third-party inspector asks for.
Our service supports [oil and gas, pipeline, power, marine and fabrication] contractors in Tanzania, Kenya, Zambia and Rwanda.
