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...

Many applications have stimulated the recent surge of interest single-chip parallel processing. In such machines, it is crucial to implement a high-throughput low-latency interconnection network to connect the on-chip components, especially the processing units and the memory units. In this paper, we propose a new mesh of trees (MoT) implementation of the interconnection network and evaluate it...

Throughout the GTA welding (GTAW) process, bead width (Bw), height (Bh), penetration depth (Dp), and metal transfer modes change in accordance with current wire feeding speed. Various processes employing GTAW include text marking systems that have as main management items, some such require sufficiently complete penetration. It is judged there will also be a type advantageous for first layer of...

Sustainability scores can be used to assess manufacturing strategies, going one step beyond a standard economic assessment. This work uses previously proposed methodology evaluate two of the most common welding processes for aluminium alloys that are specifically in fabrication components transport industry based on their advantages generating lightweight and dimensionally efficient parts. For ...

this paper deals with the investigation of the microstructure and hardness of steel samples cladded with satellite 6-wc composites by using gas tungsten arc welding (gtaw) process. for this purpose, steel samples were coated with unreinforced and reinforced stellite (by 20, 30 and 40 wt.% wc). the cladded samples were evaluated by metallographic studies, microhardness measurement and x-ray diff...
