Confirming the base metal and welding consumables compliance with the appropriate specs. Guaranteeing that the joint style and weld preparation is compliant with the WPS and appropriate welding standards (ASME, AWS, API).




Occasionally, pre-welding assessment may find abnormalities that are within code restrictions but could pose a concern at a later phase in production. That's why it's important for the welding inspector to be acquainted with the entire manufacturing procedure and to be experienced with the welded tools. Assessment during the welding procedure is necessary for identifying the weld problems and avoiding a wrong welding technique from causing huge weld denials across the whole job.

An additional example would be not evaluating for too much distortion, which would cause weld being rejected and expensive rework if done on pricey equipment like heat exchangers, purification columns, and central heating boilers. Several of the common high quality control checks during welding are: Confirmation of pre-heat and interpass temperatures and making certain that they are within restrictions defined in the WPS.


Confirm the securing gas and change are as instructed in the WPS. Examining sequencing procedures for distortion control. Tack weld high quality inspection. Confirming a proper fit-up before welding. Evaluating the origin pass and successive weld passes. Examining the root problem before welding the opposite. Making certain that slag, silica, and other contaminants are eliminated in between passes.
