Problems with ASME product impact test plates
Thread Content
Currently, the base material of the company’s products requires impact testing at -40 degrees Celsius. For the circumferential welds specified in UG84(i), there is a gasket used; the welding methods are GTAW+SAW, while for categories A and B, the methods are SMAW+SAW. Therefore, it is necessary to create impact test plates for these circumferential welds. But how should such test plates be made? According to ASME requirements, welding should be carried out under the same conditions as those used for manufacturing the container – with the same parameters and using the same equipment, either simultaneously or at an earlier stage. Is this a simulation test plate? Should it be welded in the same manner as the ring welds, with gaskets used? ? ? ?
If there is someone to witness it, then weld with padding. . . Welded it, then removed it. . No one is witnessing it; you decide how to weld it. .
OK, the AI has the witness points; I’ll bring the padding then
