Confirming the base metal and welding consumables conformity with the applicable specifications. Examining for joint cleanliness and correct fit-up. Making certain that the joint design and weld preparation is certified with the WPS and relevant welding criteria (ASME, AWS, API).




Occasionally, pre-welding evaluation may locate irregularities that are within code limitations yet can position a concern at a later phase in manufacturing. That's why it's vital for the welding inspector to be knowledgeable about the entire manufacturing process and to be experienced with the welded devices. Assessment during the welding procedure is vital for finding the weld defects and stopping an inaccurate welding approach from triggering massive weld rejections throughout the whole task.
