Welding is a joining or fabrication or structural process that joins materials, usually metals or thermoplastics, by causing merging of base metal with filler material. In “Design, analysis & manufacturing of Torch Rotary Welding SPM”, Gas Metal Arc Welding (80% argon and 20% CO2 as inert gas) is used. The main role of Automation is in cost saving and to maximize the productivity of the system. Basic requirement for any manufacturing company is to have effective work output. Circular welding is one of the most critical welding processes carried out manually, to fulfill that requirement we have used automated torch rotary welding process. In our project we have to weld two circular welding points in an automobile component. The finish component is muffler assembly. It has two points on two faces of the muffler. These two points are located at two different points in horizontal plane. Onto these two points it has the input and output pipes. To weld these two pipes with assembly we have to use fixture for avoiding the mistakes of misalignment of locations, we have design and manufacture a SPM which must carry an automate drive for uniform and precise welding. SPM1: Rotate work-piece around the welding torch. SPM2: Rotate welding torch around work- piece (muffler). Rotating the whole work-piece around the welding torch is not feasible due to the misaligned welding points along vertical axis on horizontal plane. Hence, it is not possible to construct the SPM1.Instead of SPM1, we can use SPM2 design which will allow us to manipulate the machine components as require with the (muffler). This Torch Rotary Machine is used for the welding of the muffler using the GMAW process with the help of torch. A fixture is provided on the machine for this operation. Welding torch rotates around the pipe and flange during welding. Necessary settings and adjustments are provided on this SPM to ensure smooth and safe operation of the system.
