Destructive Testing (DT)
Chisel Test for Resistance and Projection Welds
Evaluating weld integrity and nugget quality of spot welds by forcing a chisel between the sheets, in the field or laboratory.
The chisel test evaluates resistance spot and projection welded joints by driving a chisel between the sheets to load the weld and assess its integrity. Whether the weld nugget pulls out of the sheet as a button (plug failure) is examined, providing rapid information about weld quality.
