Verifying the base metal and welding consumables compliance with the suitable requirements. Ensuring that the joint design and weld preparation is compliant with the WPS and suitable welding criteria (ASME, AWS, API).




Sometimes, pre-welding examination might discover irregularities that are within code constraints however might position an issue at a later phase in production.
