Validating the base steel and welding consumables compliance with the applicable specifications. Making sure that the joint style and weld preparation is compliant with the WPS and appropriate welding requirements (ASME, AWS, API).




Occasionally, pre-welding assessment may find abnormalities that are within code limitations yet can present a problem at a later stage in production. That's why it's vital for the welding assessor to be knowledgeable about the whole manufacturing procedure and to be experienced with the welded tools. Inspection during the welding procedure is essential for finding the weld defects and protecting against a wrong welding technique from causing massive weld denials throughout the entire project.

Another instance would be not checking for extreme distortion, which would cause weld rejection and pricey rework if done on expensive equipment like warm exchangers, distillation columns, and central heating boilers. Some of the typical quality assurance checks throughout welding are: Verification of pre-heat and interpass temperatures and ensuring that they are within limits defined in the WPS.


Validate the shielding gas and change are as instructed in the WPS. Assessing sequencing procedures for distortion control. Tack weld high quality assessment. Validating a proper fit-up prior to welding. Evaluating the root pass and successive weld passes. Checking the origin problem prior to welding the opposite.
