What Is Dissimilar Metal Welding? | Metal Welding

May 19, 2020 · For some metals, buttering the joint edges with a metal that is soluble with the dissimilar metals and the filler could help the process of fusion welding. For example, depositing nickel alloy onto the weld surface of a piece of stainless steel and doing the same on the joint location of a piece of copper creates a surface that will adhere to dissimilar metal welds and weld joint design for duplexWelding metals of dissimilar strengthsCertain joint designs may allow you to undermatch the filler metals strength to the lower-strength material. For instance, some fillet joints created by joining a 100-KSI yield, quench-and-tempered material like A514 to an even higher-strength, proprietary high-strength, low-alloy 130 material can accommodate welds with 70-KSI filler metals.Welding guide Sandvik Materials TechnologyFor dissimilar joint welding (example; Stainless Steel to Carbon Steel) Consideration: Failure can occur as a result of low alloy mixtures if the incorrect filler metal is selected, or if dilution rates are too high. The most common failure mode is cracking but weld embrittlement is also possible.
