Verifying the base metal and welding consumables compliance with the applicable requirements. Making certain that the joint layout and weld prep work is certified with the WPS and relevant welding criteria check my blog (ASME, AWS, API).




In some cases, pre-welding evaluation might discover irregularities that are within code constraints however could posture a problem at a later phase in production. That's why it's vital for the welding assessor to be knowledgeable about the whole production procedure and to be experienced with the bonded devices. Evaluation throughout the welding process is crucial for identifying the weld problems and protecting against an inaccurate welding approach from creating enormous weld rejections across the entire task.
