Parametric Study of Automatic Welding to Control Hot Cracking Susceptibility in Dissimilar Metal Joints: Application to Stainless Steel/Copper Assemblies.

The joining of copper and stainless steel is crucial due to their complementary properties. The excellent thermal conductivity of copper, combined with the high strength and mechanical resistance of stainless steel, enables the creation of joints that efficiently manage heat while maintaining structural integrity. This combination is particularly advantageous in heat exchangers, fusion reactors, electronics, batteries, chemical processing, and nuclear engineering, where effective heat management and corrosion resistance are essential. However, the heterogeneous nature of these materials presents significant challenges, primarily due to differences in melting points and thermal expansion coefficients.
