Occasionally, it may be needed to examine the WPS qualification by carrying out examinations on weld coupons (test pieces). Validating the base steel and welding consumables conformity with the appropriate specs. Examining for joint cleanliness and proper fit-up. Ensuring that the joint design and weld prep work is certified with the WPS and relevant welding standards (ASME, AWS, API).




In some cases, pre-welding examination might discover irregularities that are within code limitations yet might position an issue at a later phase in production. That's why it's vital for the welding assessor to be aware of the entire manufacturing procedure and to be experienced with the welded tools. Assessment during the welding process is vital for spotting the weld issues and stopping an incorrect welding strategy from triggering massive weld denials throughout the entire job.
