Influence of Process Parameters on Weld Width of Tungsten Inert Gas Welded Joints for Low Carbon Steel AISI 1010 Plates

Abstract

The present work deals with the investigation of effect of input welding process parameters on weld width in tungsten inert gas welding process. The important input welding process parameters considered are as welding voltage, welding current, speed of welding, and the feed rate. The plates having dimensions of 75 mm × 50 mm × 5 mm from the material of low carbon steel AISI 1010 are used to obtain the weld. A total of 16 pairs of these plates are required to be welded to have 16 different welds using tungsten inert gas welding process. Welding voltage, welding current, rate of feed, and speed of welding are considered as input welding process parameters, and the weld width is selected as output parameter. Three input welding parameters are kept at constant at a time by varying the fourth parameter to investigate the effect of fourth parameter. In this way, the effect of all input welding parameters on weld width are obtained. And recorded in table number 1 and shown in Figs. 1, 2, 3 and 4. Generally, the weld width increases with increase of current, feed rate, and welding voltage but decreases with welding speed in the present work.
