Seam welding

Seam welding is a process that produces a serial of welds between two metals. The seam may be a butterfly joint or an overlap joint. Seam welding can be as roll spot welding whereby there is a certain distance between the welding spot or as a continuous weld whereby the single spots overlap each other (producing a closed weld). The process differs from spot welding by using welding wheels instead of welding electrodes, produced out of bars.

Welding wheels according to drawing

We are able to offer you machined welding wheels in different alloys according to your drawing or sample.

Laminated shunts

We produce laminated shunts and water-cooled cables for all type of welding machines, according to drawing or sample.

Contact pick up shafts and housings

Beside welding wheels, we also produce contact pick up shaft as well as shaft housings.
