Code for fire protection: Does the stainless steel pipe of proportional mixer cause argon arc welding?

Of course. According to the specification, stainless steel pipes must be welded by argon arc welding. According to the fire protection requirements, the steel pipes of the pipeline system should be welded by gas welding, argon arc welding and carbon dioxide gas shielded welding. For pipelines with pressure greater than 0.2MPa, argon arc welding or carbon dioxide gas shielded welding should be adopted to prevent leakage and fire accidents.
