Polycrystalline silicon project, the process pipeline of liquid argon and liquid nitrogen system, the process design temperature is -196℃, the pipeline material is 304 stainless steel, the working medium is liquid nitrogen and liquid argon, what kind of welding method is used for welding this kind of low-temperature working medium pipeline? Can the welding process at normal temperature be used for such low-temperature working medium pipelines?
