By comparing backgouging of plasma arc with carbon arc to the weldedjoint of 13-5 martensitic stainless steel, the backgouging of plasma arc is proved feasible for the full penetration weld.
The national standard is suitable for weldedjoint of carbon steel and low alloy steel with gas welding (being used for sheet metal), manual arc welding and gas - shielded welding.
本标准适用于气焊(用于薄板)，手工电弧焊及气体保护焊焊接的碳钢、低合金钢焊接接头。
