Resistance welding

Resistance welding is the collective name for welding processes, in which the required heat is generated by means of electric current. The welding parts are pressed together using two electrodes. A current flows through the structural parts. As a result of the electric resistance, the electrical energy is converted into heat. This heat causes local melting of the materials. This melting and solidification creates the weld.

The form of the resulting weld is dependent on the resistance welding process:

  • spot welding,
  • projection welding,
  • seam welding,
  • flash butt welding,
  • resistance butt welding.

Feasibility study

BWI can assess the feasibility of this process for your materials or applications. Through our partner network, we can also carry out welding trials with subsequent full weld characterisation. For further questions, please contact Koen Faes.
