What must a welder perform to qualify for thermite welding?

To qualify for thermite welding, a welder must perform direct examination welds. This involves subjecting the weld to thorough testing and inspection to ensure its integrity, quality, and adherence to safety standards. Direct examination allows for the evaluation of not just the visual aspects of the weld, but also its structural soundness and performance characteristics under expected service conditions. This step is critical in establishing the competency of the welder in executing the thermite welding process correctly.

In thermite welding, the weld must be able to withstand the stresses it will encounter, and the direct examinations help to identify any potential defects before the weld is put into actual service. This focus on rigorously tested and assessed welds ensures that the overall welding practices meet industry standards and safety requirements.
