Copper to Stainless Steel Welding | EB Industries

An important aspect of welding stainless steel to copper is the physical design of the joint. Problems occur if the joint is designed where the weld energy comes through the copper first. Copper, being a great conductor of heat, tends to require a significant amount of welding energy before it melts. The high amount of energy causes two problems.
