This paper describes the relationships between ultra-violet emission, ozone generation and CrVI production in MIG welding which were measured as a function of shield gas flow rate, welding voltage, electrode stick-out and shield gas composition using an automatic welding rig that permitted MIG welding under reproducible conditions. The experimental results are interpreted in terms of the physic...

Abstract Ferrous alloys are employed in a range of fields, including aerospace, construction, automobiles and chemical processing. One the most used welding processes for fusion ferrous metals is gas tungsten arc (GTA) or Tungsten Inert Gas (TIG) welding. Due to lower amount penetration accomplished using only one pass, less frequent some industrial situations. Fluxes have been discovered impro...

In fusion arc welding the final weld shape is influenced by welding parameters, mode of metal transfer, number of welding wires used and their arrangement in the contact tube, type of material to be welded, type of shielding medium and similar. In some articles, descriptions of investigations on the influence of the kind of material and the type of shielding medium used on the weld shape and si...

Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...

Abstract Hastelloy C-276 is a nickel-based alloy with high strength and corrosion resistance at cryogenic to temperatures. The issue of shallow penetration by Tungsten Inert Gas (TIG) welding was addressed in the current investigation applying A-TIG variable oxide flux. In investigation, constant conditions were used perform TIG using SiO 2 , TiO 50% mixture + weld bead width depth profile meas...

Tungsten Inert Gas (TIG) welding is a widely applied manufacturing process. Angular distortion is a major problem and most pronounced among different types of distortion in the butt welded plates. This angular distortion is mainly due to nonuniform transverse shrinkage along the depth of the plates welded. Restriction of this distortion by restraint may lead to higher residual stresses. However...

Applying non-uniform heat in welding causes residual stress and distortion, which affects the life of components. In present study, distortion Duplex 2205 stainless steel A-TIG were investigated numerically experimentally. The optimal parameters for highest penetration depth welded samples obtained Uncoupled thermal-mechanical analysis using ABAQUS 2017 software has been done. Goldak's measured...
