Difficulties of welding copper with steels

• Copper has a low value of the coefficient of gas absorption, so it is necessary to block access to the welding zone of oxygen and other active gaseous oxidants;
• The difference in melting temperatures of steel and copper cause phase heterogeneity of the resulting melt;
• The low heat capacity of copper requires constantly high temperatures in the welding area.

The only technology that is able to overcome these problems is the electric arc welding. The supplier Evek GmbH offers to buy welded copper of domestic and foreign production at an affordable price in a wide range. Provide product delivery anywhere in the continent. The price is optimal.

Location of the welding electrode

In the location of the welding electrode and the subsequent excitation of the arc the electrode is not symmetrical to the axis of the weld, but at a distance inversely proportional to the heat capacity of the metals. Thus, the electrode should be closer to the steel workpiece.

Gas shielding

The process is carried out in a stream of inert gas (argon or nitrogen), using welding fluxes. They reliably isolate the junction area from possible oxygen penetration in the air. Argon compresses the arc and thus increases the thermal power density of the arc discharge. To ensure the structural uniformity of the junction zone, argon flow rate is tried to maintain the maximum possible: at least 12...15 l/min. For the same reasons, it is less effective to use such inert gases as nitrogen or carbon monoxide. The electrodes used are either copper filler wire or tungsten electrodes.
