Abstract

Dissimilar welding offers exiting benefits for a wide range of
engineering applications, such as automotive bodies, piping systems of
nuclear power plants, health equipment. The main advantages of
dissimilarwelding applications areweight reductions, lower costs, unique
properties combinations, and improved energy-efficiency. The properties
of dissimilar weld depend on the type of welding process used, the
accuracy of the process parameters control, the characteristics of the
base metal and the heat treatment procedures. The current study reviews
the scientific literature on the topic of thermal analysis of dissimilar
high-strength steels (HSS) welding. The review of experimental data was
carried out to analyze the variable heat input effect on dissimilar
welds. The results indicate the welds mechanical properties irregularity
and reduction in toughness and tensile strength due to uneven changes
in the microstructure. Furthermore, postweld heat treatment (PWHT) often
resulted in the formation of intermetallic compounds whose properties
are dependent on the duration of treatment. The research results can be
used to optimize the heat input of the HSS welding process.
