The study of the fusion-welding process covers various
important aspects such as the metallurgical properties
of the weldments, the effect of arc temperature on
the development of post-weld residual stresses, distortion
in the base material, the physics and behaviour of
the arc with the formation and maintenance of the weld
pool. All of these activities are aimed at improving the
integrity of weld and welded structures. The development
of post-weld residual stresses and distortion in a
welded structure and microstructural changes are based
intrinsically on the thermal cycle from the welding
processes. The thermal cycle also provides information
on weld penetration and heat-affected zone geometry.
Therefore, controlling the thermal cycle is critical to
good quality welding. Computer-based simulative
mathematical welding models that can predict process
outcomes without the need for costly pre-production
