Verifying the base metal and welding consumables conformity with the appropriate specifications. Making certain that the joint layout and weld preparation is certified with the WPS and appropriate welding criteria (ASME, AWS, API).




In some cases, pre-welding assessment may find irregularities that are within code limitations but might posture a concern at a later phase in manufacturing. That's why it's vital for the welding examiner to be acquainted with the whole production process and to be experienced with the bonded equipment. Assessment during the welding process is important for identifying the weld issues and protecting against an incorrect welding approach from triggering substantial weld rejections across the entire job.

An additional instance would certainly be not inspecting for extreme distortion, which would cause weld being rejected and costly rework if done on costly equipment like warmth exchangers, distillation columns, and central heating boilers. Several of the standard quality assurance checks throughout welding are: Verification of pre-heat and interpass temperature levels and ensuring that they are within limits specified in the WPS.


Verify the shielding gas and flux are as instructed in the WPS. Evaluating sequencing treatments for distortion control. Tack weld quality evaluation. Validating an appropriate fit-up prior to welding. Evaluating the origin pass and successive weld passes. Checking the origin problem before welding the other side. Making sure that slag, silica, and various other contaminants are gotten rid of in between passes.
