The essence of the technology of welding copper with argon
Copper is widely used in the electrical industry as a metal with high thermal conductivity and low electrical resistivity. For the non-detachable connection of individual elements of copper structures, conventional welding can also be used. However, it is most effective to weld copper in an inert gas environment, in particular, argon.
Features of welding copper with argon (often the process is also in a mixture of argon with nitrogen) are:
- The need for preliminary heating of surfaces up to 350… 400C, which is essential for copper with low heat capacity;
- The need for stabilization of the arc discharge itself, for which coal or graphite billets are used;
- Use only direct polarity of direct electric current;
- Application of non-consumable tungsten electrodes (TIG method).
Welding of copper has a number of technological limitations. It is not recommended to conduct the process with the horizontal position of the parts to be joined, and also to refuse preliminary cutting of the edges of the parts if their thickness exceeds 5… 6 mm.

Sequence of welding of copper by argon
The surfaces to be joined are cleaned of dirt, and for parts with a thickness of 10… 12 mm, edge cutting is performed (products with a larger thickness are inefficient in this way, since in this case it is necessary to implement significant technological currents).
In the presence of an increased amount of technological impurities (for example, for copper grade M4) filler wire is used. With its help it is also possible to more reliably isolate the welding zone from the oxygen of the air. The filler wire must be made of copper with a higher chemical purity (for example, M2 and higher).
The choice of the diameter of the electrode depends on the thickness of the welded copper elements and the current of the welding arc. The more current, the longer the welding arc should be.
Approximate indicators of copper welding by argon are:
- Thickness of the electrode: graphite — from 6… 8 mm, tungsten — from 3… 4 mm;
- The magnitude of the current, A — 150… 500;
- Voltage on the arc, V — 12… 30.
The presence of an inert gas prevents the oxidation of the metal in the weld zone, as a result of which it turns out to be strong and uniform.
