What standards are used to determine the welding methods and welding materials for pipes and equipment?
NBT47015 has recommended welding materials; conventional ones can be used as a reference. Welding methods and materials require to be planned by specialized material engineers
NB/T47015 seems to have a 2015 version; for regular Q235B, E4316 is used
What about the welding materials for pressure vessels?
It depends on the material of your container; different materials require different welding electrodes, so you’d better take a look at that first
