The development and fabrication of fusion reactor components utilize different grades of stainless steel materials and different welding techniques. Major candidates are TIG welding, Laser welding and Electron beam welding and Narrow Gap TIG welding. The weld joints quality evaluation and their mechanical properties are to be analyzed for performance of these developed components. The welded jo...

Gas tungsten arc welding is a popular process in those applications requiring a high degree of quality and accuracy. However, this process has a big disadvantage against the substantially high productivity welding procedures. 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...

The fatigue fracture of structural details subjected to cyclic loads mostly occurs at a critical cross section with stress concentration. The welded joint is particularly dangerous location because of sinergetic harmful effects of stress concentration, tensile residual stresses, deffects, microstructural heterogeneity. Because of these reasons many methods for improving the fatigue resistance o...

Different post-weld treatment methods are used to strengthen welded joints that subjected cyclic loading. Combining High-Frequency Mechanical Impact (HFMI) with Tungsten Inert Gas (TIG) remelting is rather a new concept. In this paper, the fatigue lives of transverse attachments treated by HFMI-treatment, TIG-remelting, or combination both estimated using damage modelling and finite element del...

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, ...

Tungsten Inert Gas welding (TIG) process is an important component in many industrial operations. The TIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. This paper presents the influence of welding parameters like welding current, welding speed on strength of low carbon steel on AA1050 material during welding. A plan of experiments bas...

Plates of 3–5 mm in thickness were extracted from an AZ91D ingot and then butt joints of the plates were produced using tungsten inert gas (TIG) welding method. The TIG arc was also used to deposit welding beads on some of the thin plates. No cracking was found in the butt joints. However, hot cracking was always observed to propagate from the heat affected zone (HAZ) under the welding bead int...

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...

Plate bending fatigue tests were conducted for the Mg-9mass%Al-1mass%Zn-2mass%Ca alloy joints prepared by friction stir welding under two different conditions of stress ratio 0 and -1. The limit FSW was above 80% that base metal all test conditions. Fracture origin observed at thermo-mechanically affected zone (TMAZ) in joints. higher than inert gas (MIG) tungsten (TIG) fused (FZ) both MIG join...

The dyeing of textile materials is the most critical process in cloth production because of the strict technological requirements. In addition to the technical aspect, there have been increasing concerns over how to minimize the negative environmental impact of the dyeing industry. The emissions of pollutants are mainly caused by frequent cleaning operations which are necessary for initializing...
