The Effect of Electrode Tip Diameter on Indentation Feature and Nugget Diameter of Resistance Spot Welded Automotive Steel Joint

2021
Resistance spot welding, which is the dominant welding process with high productivity for manufacturing car body and other components, is widely used to weld various steel sheets in automotive industry. However, electrode indentation affects both the surface quality and mechanical property of resistance spot welded lap joint.

Ultrasonic Evaluation of Spot Welding Nugget Diameter with a Line-Focused Probe

Welding in the World, 2009
Resistance 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.

Study on Nugget Diameter and Joint Strength of Dissimilar Metals in Capacitor Charging Projection Welding

Key Engineering Materials, 2011
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.

Study on real-time measurement of nugget diameter for resistance spot welding using a neuro-fuzzy algorithm

Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat. No.04CH37510), 2004
Resistance spot welding (RSW) is still the most successful sheet metal joining method in the automobile industry. However, an effective quality evaluation method has not yet been developed. Real-time quality inspection of RSW is necessary in order to deal with all kinds of problems during welding.

Investigation of the correlation between dynamic electrode force signals and nugget diameter in resistance spot welding

Measurement Science and Technology
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.

Multi-objective optimisation for indentation rate, nugget diameter and tensile load in resistance spot welding using Taguchi-based grey relational analysis

International Journal of Materials and Product Technology, 2021
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.
