Abstract:

Tungsten Inert Gas (TIG) welding is widely used in fabrication industries. Distortion is major problem due to which reworks and time, cost gets affected. So it has to be controlled. The main objective of this research is to optimize the TIG welding parameters to reduce distortion in plate to plate butt weld joint of material SA203 GRADE –E. An experiment is conducted to study the effect of three TIG welding control parameters as welding current, WEP angle, preheat temperature on welding distortion. Here root gap is taken constant and welding position is same through the experiment. The Experiments were planned using the strategy of DOE. The levels of input parameters were selected and experiments were carried out. The results obtained under the combination of these parameter were analyzed by using ANOVA (analysis if variance), statistical method to investigator the critical parameter affecting the distortion in welding and their contribution.
