About The Pressure Vessel Manufacturing
- Dec 16, 2016 -

1, pressure vessel manufacturing process generally can be divided into: raw material acceptance process, line process, the cutting process, cleaning process, machining (including edge planing, etc.) work procedure, groups, and rolled to work procedure (product welding test plate), welding, NDT process, opening line process, the general inspection procedure and heat treatment process, pressure test process and corrosion process.

2, different welding methods have different welding process. Welding process is mainly according to the welding workpieces material qualitative, brand, chemical composition, weldment structure type, welding performance requirements to determine. Must first determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on, are very many different kinds of welding methods, can only be chosen according to specific situation. Determine the welding method, and then make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand), the diameter, the type of current, voltage, welding power source, polarity connection, welding layer number, number, inspection methods and so on.
