    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 alloys.
