Advances in Dissimilar Welding of Steel to Copper

Nowadays, welding of dissimilar metals benefits from the highest levels of welding technology. In the welding of dissimilar metals, considering parameters such as electrode type, welding amperage, preheating temperature and welding speed possesses higher necessity comparing with other similar metals. The use of welding methods by Shielded Metal Arc Welding and Gas Tungsten Arc Welding are practical methods in dissimilar welding of metals. The welding of 304L stainless steels to pure commercial copper has various applications in melting and casting industry; therefore, the purpose of performing dissimilar welding of 304L stainless steel to pure commercial copper is to solve the problems faced in the welding of oxygen blowing lances and copper water-cooled molds. In order to present the results of welding 304L stainless steel to pure commercial copper which was performed with the cooperation of MesParang company, this book contains an introduction to the fusion welding methods such as GTAW-SMAW hybrid welding and the electrodes used in dissimilar welding of steel to copper and its alloy. This book investigates the effect of alloying elements on the weldability of steel and copper.
