INFLUENCE OF PROCESS PARAMETERS ON DEPTH OF PENETRATION OF WELDED JOINT IN MIG WELDING PROCESS

Abstract

The effect of various welding process parameters on the weldability of Mild Steel specimens of grade EN-3A having dimensions 150mm 100mm 6 mm, welded by metal inert gas welding were investigated. The welding current, arc voltage, welding speed, are chosen as welding parameters. The depth of penetrations were measured for each specimen after the welding operation is done on closed butt joint and the effects of welding speed, current, voltage parameters on depth of penetration were investigated.
