Resistance spot and roller welding

Resistance welding is used to weld sheet metal, thus with applications in any sector

This process allows better control over the precision and pressure to be applied.
Resistance welding involves a thermoelectric process of creating heat by passing electric current between electrodes. It is an autogenous welding method, in which a fusion of the parts to be joined takes place.

The most common techniques are:

Resistance spot welding
Roller resistance welding

Spot welding can be manual, through the use of resistance welding machines, or automatic, with the insertion of spot welders into robotic resistance welding systems.

Roller resistance welding involves the use of copper discs that make spots in succession on overlapping metals.

Micro spot welding

Micro welding heads are used for precision spot-welding and welding of micro-components. These small machines have great power and a very high degree of precision.
We have designed and produced the Tecsal TM10-S, a compact, motorised head that makes the operator’s job much easier.

Resistance spot and roller welding

Spot-welding electrodes are the fundamental part of any machine.
These copper tips (or copper alloys) must be carefully chosen on the basis of shape, taper and size in order to be able to perform spot welding correctly. Using the wrong electrode can result in poor quality spot welding, both in terms of aesthetics and mechanical strength.

This is why Tecsal pays the utmost attention to electrodes. We recommend the best solutions based on the material to be welded and the type of result to be obtained.

We are also specialised in the production of electrodes for welding, both based on designs or samples.
