Online nugget diameter control system for resistance spot welding
The International Journal of Advanced Manufacturing Technology, 2013The aim of this paper is to provide an integrated real-time control system for resistance spot welding (RSW), which is capable of producing welds with predetermined nugget diameters. Nugget diameter is a commonly used criterion for estimating the weld quality; thus, the system can be used for online quality control of RSW.

Abstract Liquid metal embrittlement induced cracking of zinc-coated twining induced plasticity steels was investigated during their resistance spot welding. Crack resistance of steel was investigated in relation to liquid metal embrittlement phenomenon. It was found that there are supercritical area and critical nugget diameter for cracking the welds.

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 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 Resistance spot welding (RSW) is applied extensively by automotive manufacturers for assembling the structural and body components of vehicles. The current method of welding quality inspection is off-line inspection after welding, which cannot provide real-time feedback on welding quality and cannot meet the rhythm of modern ...
