Occasionally, it may be needed to examine the WPS qualification by conducting tests on weld promo codes (examination pieces). Confirming the base Welding Inspection Service steel and welding consumables conformity with the relevant specs. Evaluating for joint cleanliness and proper fit-up. Guaranteeing that the joint style and weld preparation is certified with the WPS and relevant welding criteria (ASME, AWS, API).




Often, pre-welding evaluation may discover irregularities that are within code constraints however might position an issue at a later phase in manufacturing.
