Regarding welding procedure qualification
Thread Content
For the installation and welding of pressure pipelines, a welding procedure qualification is required, but there are numerous standards for such qualification, including GB50236, JB4708, SYT0452, as well as ASME standards. Are there any standards that can be unified across the board? Otherwise, won’t the construction party have to prepare numerous welding process evaluations that meet various standards? It represents a huge waste of human and material resources. Does anyone have any good solutions to this problem?
Reply to 1# xuming135: We use the ASME pressure vessel code, which seems to be more authoritative. ;P
The welding procedure qualification is prepared by the factory; when you place an order, the factory will provide it to you. The content of the WPQ varies depending on the standards and materials used
