In this paper, the structural change in the heat-affected zone during welding of an SUS-304 plate is investigated in relation to the reverse transformation from work-induced martensite to austenite. The transformation occurs in HAZ and affects the mechanical properties of the welded component. The kinetic equations for the transformation are evaluated by comparing the calculated structural change with experimental results. The stress/strain analysis of the welding process is conducted based on the viscoplastic constitutive equations associated with the structural change. Emphasis is placed on the structural change in HAZ and its analysis in the simulation of the welding process, and then the properties of the welded component are also discussed using the calculated results of distributions of stresses and structures.
