Good to know
In resistance welding, it is extremely important to use electrode materials with outstanding hardness and strength at the application temperature. These properties must be retained, even after prolonged exposure to heat. The materials must also have a high softening temperature and tempering resistance. Did you know that tremendous forces of up to 450 megapascals (MPa) can occur between the electrode and the workpieces to be joined when thick sheets or similar workpieces are being welded? It is important for the electrodes to be able to withstand these stresses. This is the only way to achieve reliable welding results.

FAQ
Resistance welding is a joining process in which workpieces are attached to each using pressure and electrical resistance. Due to the high current flow and the resulting heat, the material melts and forms a solid weld seam after cooling It is used in various industries, and has advantages such as efficiency, working speed and the reproducibility of the weld seams.
Resistance welding is used in various industries, particularly ones which make high demands with regard to efficiency, precision and production speed. Industries in which resistance welding is frequently used:
- Automotive industry: Welding of body parts; particularly for welding sheet metal components and manufacturing chassis components.
- Electronics industry: for the manufacture of electronic components, particularly for the manufacture of circuit boards or connecting cables and wires.
- Aerospace: for aircraft structures and engine components.
- Construction industry: Metal structures and steel structures, welding of metal parts for construction projects.
- Household appliance industry: Washing machines, dryers and refrigerators.
- Power generation: Manufacture of components for power plants.
On the whole, back-cast electrodes have a longer service life, better heat dissipation, reduced oxidation and optimal current distribution, which results in improved weld quality and efficiency.
