In this paper, 8 mm thickness 2205 duplex stainless steel (DSS) plates were successfully welded using keyhole tungsten inert gas welding (K-TIG) welding, and numerical simulations performed applying the finite element method. Three models of combined heat source adopted to verify accuracy experiment. The process under different speeds simulated, temperature field, molten pool shape, thermal cyc...

Abstract The friction stir processing (FSP) technique was employed on the AA6082-AA8011 TIG-welded joints to investigate contribution of conditions microstructure and mechanical properties processed joints. were subjected FSP under normal submerged conditions. tests conducted included microstructural analysis, tensile, Vickers hardness fracture surface analysis. analysis showed minimum average ...

The aim of this study is to fabricate in-situ TiC particle reinforced Fe matrix composites via volume combustion synthesis (VCS) through heating by two different sources. One group reactant pellets was ignited in an induction furnace (IF). other using a tungsten inert gas (TIG) torch. Thus, the differences microhardness and microstructure obtained could be compared. Fe, C Ti elemental powders w...

Abstract. It is possible to assess the thermal efficiency of welding shielding gases by means of the arc temperature field analysis. Since this approach opens a remarkable study field to assess different shielding gases, giving support for dealing with advantages and disadvantages of commercial gas mixtures, there is a research line under development, which goal is to find techniques to measure...
