Ultrasonic Evaluation of Spot Welding Nugget Diameter with a Line-Focused Probe
Welding in the World, 2009Resistance spot welding has been widely used for the construction of thin sheet metal structures. The structures’ reliability depends upon the weld quality as well as the weld size. Therefore, various non-destructive inspections have been applied to the spot welds.

Abstract Resistance spot-welded tensile shear specimens with three nugget diameters— 5 t , 6 t and 7 t —were prepared with low- and high-strength cold-rolled 301L plates. Static overload and fatigue examinations of the spot welds were conducted to investigate the effects of the nugget diameter on their mechanical ...

Abstract As a process signal in resistance spot welding, dynamic electrode force more prominently reflects the nugget formation process. To quantify the correlation between dynamic electrode force and nugget diameter, a non-destructive measurement method based on dynamic electrode force is proposed.
