Gas-Shielded Tungsten Arc Welding (GTAW) was modified to a Flux-Cored-Double-Wire GTAW (FCDW-GTAW); in this technique, wires of different compositions are used simultaneously obtain microstructures. In the GTAW, automatic flux-cored double-wire with combination four deposited AISI1020 steel, allowing Pin-on-disk wear tests described by ASTM G99 evaluate coefficients hardfacing materials combini...

Process This chapter presents the principle of tungsten inert gas (TIG) welding process besides important components of TIG welding system and their role. This process is also known as gas tungsten arc welding (GTAW) process. Further, fundamentals of heat generation, arc stability and arc efficiency have also been described. Additionally, comparison of argon and helium as shielded gases has bee...

Visual sensing technology is widely used in welding practices because visual devices are decreasing in price, increasing in reliability and improving in image processing hardware and software. As the most studied welding sensor, CCD(Charge Coupled Device) is more suitable for quality control of welding process than other means of sensing devices because it can obtain both two dimensional and th...

Offshore building construction is inseparable from the fabrication process. Fabrication process that has an important role in terms of engineering, material repair and welding In offshore construction, a precise method needed on A36, where A36 steel one main materials buildings. this study comparison results GTAW, GMAW, FCAW against Tensile Test Macrostructure Test. The research show best tensi...

Tungsten metal arc welding (GTAW) is a highly popular technique in manufacturing. The factors such as current, voltage, speed, and gas flow rate play significant role determining the quality. This study discusses effect of GTAW on mechanical properties commercial steel welding. Base thickness, current are to be optimised for maximum tensile strength hardness by Taguchi design (TD). analysis sho...
