Verifying the base steel and welding consumables conformity with the suitable specs. Ensuring that the joint style and weld preparation is certified with the WPS and suitable welding standards (ASME, AWS, API).




Sometimes, pre-welding evaluation may discover abnormalities that are within code constraints however could posture an issue at a later stage in production.
