The effect of various welding process parameters on the weld ability of stainless Steel specimens of grade 312 having dimensions 75mm× 55mm× 6 mm, welded by plasma arc 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. The main motivation of this project is to increase the welding depth. Next thing is to improve the welding quality and decrease the production cost of the stainless steel. But it is not improved at all sides, till now welding depth is below 3mm. So our particular aim is to improve the welding depth and also to establish the perfect method for welding in stainless steel materials
