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.

 

  1. BS1140: - British Standard specification for Resistance spot welding of uncoated and coated low carbon steel.
  2. ISO 10447: - Welding - Peel and chisel testing of resistance spot, projection and seam welds.
