Environmental Criteria for Shielding Gas Selection during Arc Welding of Stainless Steels

Abstract:

Gas-shielded arc welding of stainless steels belongs to processes which are characterized by the highest concentration of chromium (VI) and nickel in welding fume. These substances are carcinogenic to humans. Material and technological conditions of gas-shielded arc welding of stainless steels influence fume emission rates and chemical composition of welding fume. This fact creates the possibility of process optimization in aspect of emission rates and chemical composition of welding fume including carcinogenic compounds. This paper presents the correlation between shielding gas compositions and fume emission rates and carcinogenic substances contents during gas-shielded arc welding of stainless steels using MIG/MAG, Cold Arc and CMT methods.
