Destructive and non-destructive weld testing
When testing welded materials for defects there are two main types of test that can be carried out. Destructive (breaking the weld appart) and Non-Destructive (not breaking the weld appart)
Below is a short description of some of the available techniques.

Common defects in welding:
Resistance welding
Resistance welding is conducted as follows:
Apply force and current through electrodes in contact with metal parts to be welded; resistance heat is generated at the interface of metal parts and makes a nugget, resulting in melt joint.
Though a large current flows, there is no danger of an electric shock because only low voltage is impressed.

- ISO 10447: - Welding - Peel and chisel testing of resistance spot, projection and seam welds.
