This study investigates the combined effect of Tungsten Inert Gas (TIG) and Metal (MIG) arcs in achieving improved mechanical microstructural properties compared with standalone TIG MIG based on optimum parameters setting for welding processes. Miller machines a maximum capacity 400 A were used as heat source. The welds produced by TIG-MIG, processes characterized via tensile hardness testing, ...

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...

This research paper presents hardness, structure and tensile strength analysis of 1460 alloy Al-Cu-Li system, welded joints made by Tungsten Inert Gas (TIG) welding Friction Stir Welding (FSW). Characteristics acoustic noise at the operator workplace during mechanized TIG FSW aluminium-lithium with purpose to develop recommendations for improvement health safety processes were studied. Analyzin...

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...
