| Abstract | The manufacturing activity as an industry is always the key parameter for the development of any nation. The large-scale lucrative businesses of fabrication of vessels for oil and gas, automotive and its ancillaries, aerospace sectors, etc. are always critical and challenging task to perform. A considerable amount of research, care, and inputs are required for the successful delivery of the component. Thus, welding is one of the most challenging tasks that needs special attention in the manufacturing sector. The successful welding now calls for optimum quality, reduced cost, and faster completion. Number of conventional welding processes exist are in operation since long; however, while selecting the process, a careful consideration is needed on the final application of the component. Several applications require very high-quality joints such as pipes and components for oil refining such as pressure vessels and boilers (Dhandha and Badheka 2015). These components operate at high pressure and temperatures, and hence any predicament on its safe working will be fatal. In general, tungsten inert gas (TIG) welding process is a widely accepted welding process wherein high-quality joints are intended. However, the major disadvantage of the TIG welding process is its relatively low penetration 238capability, particularly in single-pass autogenous (without filler metal mode) operations. The maximum weld penetration with the autogenous TIG welding is restricted to 3.0–3.5 mm in a single pass, making the welding of components of 6 mm or higher impossible to weld in a single pass (Vasantharaja and Vasudevan 2012, Naik et al. 2017, Vaishnani et al. 2017). The manufacturers hence resort to either double-sided welding which is not possible every time due to accessibility issue from the other side, design constraints, and challenging component handling (for reversing) in over dimensional vessels or carry out the welding from one side by adding filler metal into the groove which involves implications of cost, time, and energy. Thus, a need for devising a variant of TIG welding which can solve the problem was sensed. |
