Welding sequence optimisation in the automotive industry: A review

Abstract

Spot welding is the most common technique used to join sheet metals in the automotive industry due to the fast rate of production. Optimising the welding process including the sequence, number and location of the welds would significantly improve the quality of the final product and production cost. This paper presents an overview on the available methods to plan and optimise various aspects of the welding process including welding sequence, weld quantity and location. Firstly, the welding concept in the automotive industry is briefly reviewed. Secondly, the welding process optimisation with emphasis on the welding sequence is discussed. The common gaps and challenges are identified and, lastly, future research to plan and optimise the welding sequence in the automotive body is outlined.

Fabrication sequence optimization for minimizing distortion in multi-axis additive manufacturing

“…These issues have large impacts on the structural performance and dimensional accuracy, e.g., for assembly. In the related field of welding, the sequence of joining is found to significantly influence the development of residual stresses and distortion [12,13]. For instance, depending on the welding sequence, the distortion in pipes can vary by more than seven times [14].…”

Investigation of the effect of different welding parameters on tensile properties and failure modes of non-alloyed steel produced by powder metallurgy

“…14 Welding characteristic is an important subject because automobiles contain thousands of RSW. 15,16 Components' electrical resistance, cause heat generation and combine the workpieces with electrode force (EF). According as the surface situation of the sheets and EF.…”
