Welding Guidelines for Stainless Steel and Nickel Alloys

Stainless steels have a rate of thermal expansion 50% greater than carbon steels. Nickel alloys expand to a lesser degree. Use frequent tacks, or skip welding to reduce stresses. Minimize weaving techniques which result in slower travel speeds and higher heat input. Stringer beads are most desired when welding on stainless steel or nickel base Welding classifications:Carbon and low-alloy steels AWS Mar 18, 2020 · The compositions of carbon steels typically include weight percentages of up to 1.00% carbon, 1.65% manganese and 0.60% silicon. Steels identified as low-carbon steels contain less than about 0.15% carbon; mild steels contain 0.15%-0.30% carbon; medium-carbon steels contain 0.30%-0.50% carbon and high-carbon steels contain 0.50%-1.00% carbon.
