A good CWI understands and recognizes the specs and code. After that, he or she sees to it that the WPS and welder certifications comply with those requirements. Before welding, CWIs check both base metals and filler metals, noting that they comply with the WPS and task requirements.


Throughout construction, CWIs examine a variety of products to make sure that the WPS and project specs are being correctly followed. These products consist of interpass temperature levels, sufficient combination, cleansing, travel speed, and weld deposit dimension. Examination during welding is in some cases ignored, but it is an important component of guaranteeing weld high quality.

Sometimes, it may be required to check the WPS credentials by conducting tests on weld discount coupons (test pieces). Confirming the base steel and welding consumables conformity with the applicable specs. Checking for joint sanitation and correct fit-up. Ensuring that the joint design and weld preparation is compliant with the check my blog WPS and applicable welding requirements (ASME, AWS, API).




In some cases, pre-welding inspection might discover irregularities that are within code limitations yet could posture a problem at a later stage in manufacturing.
