Occasionally, it might be needed to check the WPS credentials by performing examinations on weld promo codes (test pieces). Validating the base steel and welding consumables conformity with the suitable requirements. Checking for joint cleanliness and proper fit-up. Ensuring that the joint design and weld prep work is certified with the WPS and suitable welding criteria (ASME, AWS, API).




Often, pre-welding examination might find abnormalities that are within code restrictions however can pose a concern at a later stage in manufacturing.
