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...

BACKGROUND Metal Inert Gas (MIG) welding and Tungsten Inert Gas (TIG) welding are widely used for mild steel segments in basic metal industries. Pulmonary problems such as asthma, pulmonary inflammation, hyper-responsiveness of airways and higher susceptibility to infections are reported as the result of occupational exposure of welders to ozone and nitrogen oxides. Potent oxidizing agents like...

A plasma arc welding (PAW)-tungsten inert gas (TIG) hybrid welding process is proposed to weld pure nickel. In PAW-TIG welding, the arc of the PAW was first to be ignited, then TIG was ignited, while in PAW welding, only the PAW arc was launched. This paper investigated the effect of different welding processes on electrochemical and corrosion performance of between a pure nickel joint and a ba...

gas tungsten arc welding is a popular process in those applications requiring a high degree of quality andaccuracy. however, this process has a big disadvantage against the substantially high productivity weldingprocedures. hence, many efforts have been made to improve its productivity. one of these efforts is the use of activating flux (a-tig welding). in this study, the performance of a-tig w...

This work focusses on analysing mechanical properties and microscopic assessment into Inconel-718 plates in welded unwelded conditions. Welding was performed by tungsten inert gas welding technique. Two tests such as tensile test hardness were both the types of to compare joint plate. Although Inconel 718 possesses good weldability, strength, ductility, reported lesser than these Unwelded The m...
