Pressure vessel, in English: pressure vessel, refers to the enclosed equipment that contains gases or liquids and carries a certain pressure. equipment to carry a certain pressure.
1, pressure vessel manufacturing process can be generally divided into: raw material acceptance process, scribing process, cutting process, rust removal process, machining (including edge shaving, etc.) process, rolling process, grouping process, welding process (welded product test plate), non-destructive testing process, opening and scribing process, the general inspection process, heat treatment process, pressure testing process, corrosion protection process.
2, different welding methods have different welding processes. Welding process is mainly based on the material of the welded workpiece, grade, chemical composition, type of weldment structure, welding performance requirements to determine. First of all, to determine the welding method, such as hand arc welding, submerged arc welding, tungsten argon arc welding, fusion electrode gas shielded welding, etc., the variety of welding methods is very large, can only be selected according to the specific circumstances. Determine the welding method, and then develop the welding process parameters, welding process parameters of different kinds, such as hand arc welding mainly includes: electrode type (or brand), diameter, current, voltage, type of welding power supply, polarity connection, the number of layers of welding, the number of channels, inspection methods and so on.
