Engineering and Technical Investigations Welded Notch Toughness Test

The welded notch toughness test determines the actual toughness of a welded joint by joining two beveled base plates with a small land area (4 mm typical) of similar or dissimilar metals. When welded together in a rigid fixture, they form a natural, sharp notch. Welding conditions can be controlled to measure the effects of voltage, amperage, travel speed, electrodes, different welding processes or various combinations of base metals. Beveling 30 deg on each plate results in a 60° included angle, providing a CVN-style weld joint; or, if one plate has a 45° bevel and the other is square-cut, the toughness of the HAZ can be found. Test fixture is portable, and provides high shrinkage restraint for welded plates.
