Failures in Spot Welding

Abstract

Resistance spot welding is an extensively used welding process for joining thin metal sheets in
automobile, rail and aircraft industries. Research on resistance spot weldability of stainless steel attracts more and
more attention with the increasing usage of various types of stainless steel in industries.Resistance spot welding is
used to join two or more metal sheets together, and the technique is used widely in theautomotive industry, for
example. Furthermore, other metal-to-metal connections, such as wire-to-wire joints inthe electronics industry, are
accomplished by resistance spot welding. In this paper, a review of works done on failures arrive in resistance spot
welding is presented.The areas chosen for most of the works by researchers in the past have been found as process
modelling and finite element analysis, dissimilar metal welding, failure mode analysis, parametric optimization and
characterization of resistance spot welds. The information presented in this report may definitely give the fresh
researchers, a view of the research work done in the past, in this field, and is expected to provide them the right
direction for the future research work, in this area.
