Investigation On the Effect of Process Parameters On Weld Bead Geometry in TIG Welding

Abstract

TIG welding is most vital and common operation used for joining of two similar or dissimilar parts with heating the material or applying the pressure by using the filler material for increasing productivity with less time and cost constrain. When changing the welding parameters, the quality, strength and weld bead geometry also affected. The TIG welding is done on the aluminium 5052 material by varying the welding parameters like welding current and welding electrode diameter. The effect on the weld bead geometry is studied and the changes made on the weld bead are noted. To analyse the strength of the weld joint or any deviation in their strength we should test the weld joint. We tested the weld joint by tensile and microscopic test. The tensile test gives any deviation in their strength and the microscopic test give the material structural changes.
