The welding use correct process parameters will produce joint with optimum in mechanical properties. current is a very important parameter welding. Gas Tungsten Arc Welding carbon steel A53 Gr B uses variations can be an option to get the best quality joints. purpose of this research properties and microstructure by varying current. experimental method GTAW A 53 using single V butt 5G position,...

A smart, bi-directional model has been developed to determine three-dimensional temperature profiles, weld geometry and the transformed phase fraction during gas tungsten arc (GTA) butt welding. The model is capable of estimating input parameters such as the net input power, welding speed, effective thermal conductivity, and, activation energy, preexponential factor and exponent in JohnsonMehl-...
