A timely inspection might prevent a whole set of bad welds resulting from bad joint cleanliness or fit-up.




Occasionally, it may be needed to test the WPS certification by carrying out examinations on weld coupons (test items). Validating the base metal and welding consumables compliance with the suitable requirements. Examining for joint tidiness and correct fit-up. Guaranteeing that the joint design and weld prep work is certified with the WPS and relevant welding standards (ASME, AWS, API).




Occasionally, pre-welding examination may find irregularities that are within code restrictions however could present a concern at a later phase in manufacturing.
