Must a welding procedure qualification report be prepared by a qualified organization?
Thread Content
Is the weld evaluation report issued by a third party or by the construction unit?
The evaluation is also carried out by the production or construction unit. However, it should be noted that process qualification must be carried out in accordance with the requirements of relevant **standards (such as standards for pressure vessels, standards for welding of steel structures, etc.). Moreover, the welding conditions used for this qualification (such as welding equipment, welders, joint types, welding materials, etc.) must be consistent with those used in actual production (construction). Furthermore, the test results must be issued by a qualified assessor. Prepare the procedure for welding process evaluation: Determine the main types of joints to be evaluated based on the product → Prepare the \"Welding Process Procedure Sheet\" → Material analysis reports (with certification required) → Preparation of welding test pieces → Preparation of welding equipment and fixtures → Preparation of welders → Welding of the test pieces → Performance testing of the test pieces (with authoritative certification report) → Prepare the \"Welding Process Evaluation Report\"
Reputable construction companies should all have their own welding procedure qualification certificates
