In some cases, it might be essential to test the WPS certification by carrying out examinations on weld coupons (examination items). Verifying the base metal and welding consumables compliance with the suitable requirements. Inspecting for joint cleanliness and proper fit-up. Making sure that the joint layout and weld prep work is certified with the WPS and relevant welding standards (ASME, AWS, API).


Sometimes, pre-welding inspection may discover irregularities that are within code constraints yet might position a concern at a later phase in production. That's why it's essential for the welding examiner to be familiar with the whole production process and to be experienced with the bonded tools. Examination during the welding process is necessary for identifying the weld defects and protecting against a wrong welding strategy from creating large weld rejections throughout the entire task.
