Often, it may be essential to check the WPS qualification by conducting examinations on weld vouchers (test pieces). Validating the base metal and welding consumables compliance with the applicable specs. Evaluating for joint cleanliness and appropriate fit-up. Making sure that the joint design and weld prep work is compliant with the WPS and appropriate welding criteria (ASME, AWS, API).
