How does stud welding work?

During stud welding, an arc is ignited between one end of the stud and the workpiece. Both joining partners are melted and then joined under low contact pressure. The stud welding process usually takes less than a second.

Stud welding can be used for both round and rectangular cross-sections. In addition to the stud welding which is widely used and standardised in DIN EN ISO 13918, a large number of welding elements according to customer-specific or factory standards can be found in the various metal-processing industries.
