What precautions need to be taken when installing low-temperature dual-grade stainless steel pipes that need to be answered urgently?

Welding method GTAW, welding material selection refers to NB/T47015 "Pressure Vessel Welding Regulations". Double argon protection (argon filling in the pipe) is used when welding if possible, and welding parameters are selected according to the welding process evaluation.

Previous projects used GTAW+SMAW, which was fine for filming, but the efficiency was too low!
