Material combinations in stud welding

Material combinations in stud welding for the capacitor discharge process largely determine the load-bearing capacity of the subsequent joint. Which materials can be joined reliably depends on their metallurgical properties. In this overview, Bolzenschweißtechnik bsk + BTV GmbH provides an overview for designers and production planners. For welding onto sheets of various thicknesses, all combinations such as steel, stainless steel, aluminium or brass are clearly summarised in our chart. To monitor these industrial processes in accordance with standards, all welds must meet strict criteria. The detailed regulatory requirements can be found on our information page about DIN standards in stud welding . The table is provided below as a practical document.

The alloying constituents of the base materials also play a key role in arc-based processes such as conventional drawn arc welding (ARC) and fast short-cycle drawn arc welding. Not every material combination behaves identically with longer welding times, so current, time and lift parameters must be coordinated precisely. Reproducible weld quality requires the guidance for the respective process and the requirements applicable to the application to be taken into account. Thermal effects depend on materials, geometry and welding parameters. Use our overview table for daily planning of series production on workpieces of various thicknesses.
