Features and the difficulty of welding copper with stainless steel
The main problem of strength of a welded joint formed by these metals is the large difference in conductivity. To overcome these difficulties, the weld area is necessary to introduce a significant density of thermal power. The most accessible of such sources is the plasma formed by the burning of electric arc. However, the usual heat of the arc dissipated in the arc column, and the remaining heat for welding is not enough. Output is to further localize the zone of connection, for example, flux. And in order to exclude ingress of oxygen through the relatively porous layer fluxes, in addition to the treatment area serves under the pressure of the inert gas is carbon dioxide, or — more likely — argon.
The welding parameters of stainless steel with copper by this technology are as follows:
- Current, A — 200…280;
- Arc voltage, V — 20…25;
- The argon consumption, l/min — 12…15.

The sequence of welding of copper and stainless steel
First, in the area of the weld formation moves in argon, then excited by an electrical arc and a filler rod is introduced. In it should be composed of chemical elements contained in welded components: copper and Nickel, the presence of which improves the melting process.
Argon flow is controlled at the maximum level. As heavier density gas, it provides a reliable isolation of the weld zone from the surrounding environment, thereby eliminating the penetration of oxygen into the finished seam. With the increase of pressure reduces the metal sputtering. Process energy consumption is reduced if the welding is to implement a pulsed current source.
