Resistance welding
Resistance welding is one of the oldest types of welding. Heat is generated by the
passage of an electric current through the resistance formed by the contact between two
metal surfaces. The current density is so high that a local pool of molten metal is formed,
joining the two parts. The current is often in the range 1 000-100 000 A, and the voltage
in the range 1-30 V.
We usually distinguish between five different types of resistance welding:
1.spot welding
2.seam welding
3.projection welding
4.resistance butt welding
5.flash welding
Resistance welding methods are generally fast, efficient and low-polluting. No filler
materials are required. The drawbacks can be high capital cost and a somewhat limited
range of applications. In principle, each machine can be used for only one type of
welding.
