Abstract

An in-process method for controlling welding distortion in fillet welds is developed. It particularly reduces angular distortion by performing reverse-side Tungsten inert gas (TIG) heating of the weld line at a fixed distance ahead of metal inert gas (MIG) welding during the weld process. Various heating conditions are examined by experiment and by the finite-element analysis in order to determine appropriate conditions and to study the mechanism by which welding distortion is reduced. It is consequently found that this mechanism is a result of two main effects: TIG heating effect on the reverse side, which produces the opposite angular distortion, and preheating effect.
