The aim of this study is to investigate the optimization process parameters for Metal inert gas welding (MIG). In the present work, bead-on -plate welds were carried out on MS 5986 Fe 410 carbon steel sheets using Gas Metal Arc Welding (GMAW) process. In this present investigation ER70S-6 solid wire having 1.2 mm diameter was used as an electrode with direct current electrode positive polarity....

Abstract Residual stresses and strains, distortions, heat-affected zone (HAZ), grain size changes hardness variation during gas metal arc welding (GMAW), are fundamental aspects to study control processes. For this reason, numerical simulations of the processes represent more frequently used tool better analyse several characterizing joining process with aim reduce lead time production costs. I...

Numerous GMAW processes have appeared for one-pass welding of medium to high thickness. This concept originated in the 1980s with T.I.M.E. technique and 1990s 2000s saw emergence Rapid Arc, Melt Buried Arc techniques. These did not include any special control features, but rather parameter combinations improve bead geometry. A new interpretation factors that are critical achieving performance (...

The use of the welding process on an industrial scale has become significant over years and is currently among main processes for joining metallic materials. Along weld, structural changes occur in vicinity joint. These thermal stresses geometric distortions are mostly undesirable complex to predict with precision. Using S235JR steel as base material, laboratory experiments were carried out usi...
