Whatever form the semi-finished product takes, be it a rivet, a tip or a wire, several techniques exists to assemble a contact on its support.
- Riveting consists of mechanically fixing a rivet on its support. No external material is required for this process. The shank of the rivet is distorted to produce a coherent, stable assembly (detailed information on the subject of riveted assemblies).
- Flame brazing is used with wide-diameter tips in the presence of an additional metal (in the form of brazing blanks or paste). A flame melts the brazing material producing a metallic bond between the tip and its support (further information on brazing).
- Electric brazing also requires the use of an additional metal (brazing blanks or paste) but in this case an electrode provides the energy to melt the brazing material and create the metallic bond between the tip and the support (further reading on tip welding).
- Assembly by induction once again requires the use of an additional metal. A small inductor provides the energy (induction) to melt the brazing material. The size of the inductor depends on the size and geometry of the tip (more on brazing).
- Direct electric welding results in a tip or wire being welded onto the support without the use of any brazing material (detailed information on welded products).
