Pulsed TIG Welding, Mechanical Properties, Tailored Welded Blanks.Abstract
The present paper reports experimental results on enhancement in mechanical properties of tailored welded blanks due to Pulsed TIG welding. Experimental evaluation of various mechanical properties has been made under the influence of varying peak current, pulse frequency and pulse width. The resulting welds have been checked for ultimate tensile strength, % elongation, hardness, toughness and fatigue life. The mechanical properties of Pulsed TIG welded tailored blanks have further been compared with that produced by conventional TIG welding. It has been observed that the Pulsed TIG welding can successfully be employed to improve the mechanical properties of tailored welded blanks. The results of experiments have been analyzed and related discussion has been presented.
