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...

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...

Fe-2.25Cr-1Mo a widely used material for headers and steam tubes of boilers. Welding of steam tube to header is required for production of boiler. Heat affected zone of the weld can have poor mechanical properties and poor corrosion behavior leading to weld failure. The cost of material used for steam tube and header of boiler should be controlled. This study propose a new materials design for ...

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...

A comparative study to investigate the influences of single component fluxes on depth-to-width ratio (DWR) oxygen free copper was carried out with novel variants tungsten inert gas (TIG) welding namely Activated TIG (A-TIG), Flux Bounded (FB-TIG) and Zoned processes. The experiments identify delivering higher DWRs in A-TIG among thirteen distinct were followed by trials FB-TIG FZ-TIG employing ...

Welding is the process of coalescence two metals/alloys for creating a seamless joint, quintessential fabrication utilised in almost every manufacturing sector. There range welding processes that are used according to their features and requirement fabricator. The tungsten inert gas (TIG) an extensively owing its inherent characteristics like high weld quality, surface cleanliness, autogenous m...
