Carbon electrodes

When using carbon electrodes, there are sharp temperature differences between individual sections. Due to the high thermal conductivity of copper, this causes significant stresses, which may result in cracks after welding. Therefore, welding with graphite electrodes is only suitable for joints of significant thickness.

Electrode wire

Arc welding of copper using electrode wire gives more stable results, but for this purpose, the composition of the sheathing must be fully consistent with the copper grade. Otherwise, other elements may be present at the weld edges/boundaries, which will also cause residual stresses. The binder usually contains a dry charge, which is mixed with sodium silicate. The disadvantage of the method is the presence of pores in the finished weld.

Flux

The best results are achieved by flux welding with a non-consumable tungsten electrode. High-temperature ceramic compounds are added to the flux. Supplier Evek GmbH offers to buy welded copper of domestic and foreign production at an affordable price in a wide range. We provide delivery of products anywhere in the continent. The price is optimal.

The sequence of arc welding

The filler material is put in the joint between the parts to be welded;
The electrode is sharpened in the form of a spatula, in order that the heat spreading from the arc was more uniform;
The welding area is covered with flux;
Turn on current (process polarity - reversed), then first heated welding area briefly touching the electrode, and then increase the current on the basis: 1 mm of thickness products need 75 ... 100 A;
Adding wire is fed. To maintain the required structural homogeneity, it should be copper wire of M0 or M1 grades. The speed of the electrode on the surface should be the maximum possible, and not less than 1 mm / s.
