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,...

Abstract Tungsten inert gas (TIG) welding is frequently used to fabricate super duplex stainless steel weldments due its superior mechanical qualities and attractive appearance in contrast with other arc techniques. The broad use of TIG remains constrained despite all advantages. Thus, the process activated flux tungsten (A-TIG) created. In current study, ATIG different oxide fluxes execute bea...

Fluid flow motion controls energy transfer in the weld pool and drives solidification process. Experimental investigation of fluid during welding is made particularly difficult by unsteady movements molten pool. In this paper, proper orthogonal decomposition (POD) based on images gas tungsten arc (GTAW) thin plates used to investigate coherent structures revealed thermal field The POD method fl...
