Abstract
The paper gives results of investigations of the effect of some techniques on iron content of the weld metal in copper to steel joints made by submerged-arc welding. A new method was developed for welding of copper to steel by using a split electrode consisting of different-diameter wires. The method allows controlling heat input into the copper and steel edges, simplifies the process of tracking the weld line by electrode, and provides the required quality of the welds.
