Arc welding processes, such as shielded metal arc (SMAW), inert gas (MIG), and tungsten (TIG), play an important role in industrial applications. To improve the efficiency of exploitation traditional systems, new technologies have been used. Virtual reality technology is one them. The virtual (VR)-based system enables to increase frequency practice help learners obtain experience avoid errors t...

An asymmetric Abel inversion processing system was developed to establish a method for diagnosing arc plasma that has an elliptical cross section and is non-axisymmetric in the direction perpendicular observation during welding process. This applied tilted tungsten inert gas (TIG) As result, when this intensity distribution due integration, it confirmed relative error near central axis edge lar...

Abstract While the application of Smoothed Particle Hydrodynamics (SPH) method for modeling welding processes has become increasingly popular in recent years, little is yet known about quantitative predictive capability this method. We propose a novel SPH model simulation tungsten inert gas (TIG) spot process and conduct thorough comparison between our implementation two finite element (FEM)-ba...

Abstract Inconel 690 has been extensively used in steam generator tubing materials for pressurized water reactors. In order to improve the weld quality of 690, ultrasonic-assisted pulsed tungsten inert gas (TIG) welding is studied. this study, macrostructure, microstructure, and mechanical properties weldments welded by TIG with without ultrasonic assistance were investigated. The microstructur...

Economic welding of thick steel plates is an emerging challenge for various engineering applications. However, tungsten inert gas (TIG) arc welding, as economic and widely used method, not regarded a suitable tool to weld due the shallow penetration in single-pass operation. In this technical progress, joining austenitic high manganese 8 mm thickness was successfully performed using nanowire fl...
