When working on pressure vessel processes, how should the process qualification for weld joints be selected?
Thread Content
I would like to ask everyone: when carrying out process development, how should one select the appropriate process evaluation? For example, the thickness of the cylinder is 14 mm, and a manhole with a DN350 diameter is to be created; the thickness of the manhole cover is 11 mm, while the thickness of the reinforcement ring is 14 mm. How should one choose the welding process? From what perspective should this be approached? In addition to considering factors such as the thickness and material of the test pieces, as well as the suitability of the electrodes and fluxes and the heat treatment temperature, what else needs to be taken into account? Please explain, thank you
