Seam welding

Seam welding

With seam welding, the electrodes are two round copper alloy rollers. The rollers run at a specific speed over the work piece and project the desired welding current onto the work piece. It is possible to make a continuous weld with seam welding.

 

Seam welding is a process where two parts are welded together by two rotating electrodes. The required heat generation is obtained from the electric current and the transfer resistance between the parts to be joined.

Principle of the resistance welding process

With resistance welding, two or more plates are pressed against each other by copper alloy electrodes. The copper alloy electrodes are cooled by water. Either DC or AC can be used to weld.

During welding a resistance is created that generates heat. The greatest heat generation is located where the resistance is highest. This is between the plates to be joined. The force of pressure forces the material together into a single join/weld. The electrodes are cooled in order to reduce wear on them.

With seam welding the electrodes are two round copper alloy rollers. The rollers run at a specific speed over the work piece and project the desired welding current onto the work piece. It is possible to make a continuous weld with seam welding. It is also possible to produce a continuous row of spot welds. This process is normally used for producing oil drums and radiators. In ISO 4063 the process is referred to as process number 22.
