Occasionally, it might be required to check the WPS credentials by conducting tests on weld promo codes (test pieces). Verifying the base metal and welding consumables conformity with the suitable requirements. Inspecting for joint tidiness and correct fit-up. Ensuring that the joint design and weld prep work is certified with the WPS and suitable welding criteria (ASME, AWS, API).




In some cases, pre-welding inspection might discover irregularities that are within code constraints however might position an issue at a later phase in production. That's why it's vital for the welding examiner to be accustomed to the whole manufacturing process and to be experienced with the bonded devices. Evaluation throughout the welding process is essential for identifying the weld problems and avoiding a wrong welding technique from causing substantial weld beings rejected throughout the entire task.
