Assessment of nugget diameter of resistance spot welding using pulse eddy current thermography
Thermosense: Thermal Infrared Applications XL, 2018This paper deals with the use of eddy current thermography for spot weld nugget diameter assessment. As a nondestructive testing method, eddy current thermography is successfully used to give an estimation of the nugget diameter of resistance spot weld.

The purpose of this study was to investigate the effect of operating conditions on nugget diameter and joint strength of KOVAR alloy and SPCC steel in projection welding of dissimilar metals. All projection welds were produced with a capacitor charging power supply. Harris and Riley type projection was embossed on SPCC steel sheet.

Abstract In this work, a systematic research was undertaken to predict the nugget size of the welding joints in real time through monitoring the dynamic power signature for TC2 titanium alloy. The welding current in the welding process was measured by a Rogowski coil and the welding voltage was obtained by means of clipping two leads onto the upper ...

Abstract This paper presents an experimental study on the fatigue strength of resistance spot welded galvanized steel sheets and austenitic stainless steel (AISI 304) sheets. The sheet materials were joined by using resistance spot welding as a lap joint. Material combination and nugget diameter were selected as experimental parameters.

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.

In this study, a multi-objective optimisation method based on grey relational analysis with weighted responses is conducted to optimise the RSW parameters of electrode force, welding current, and welding time. Three objectives, such as indentation rate, nugget diameter, and tensile load, are simultaneously optimised.

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 ...
