Abstract

In recent times, manufacturing industries have shown more interest towards Automation. In other words, the industries today emerge with evolving technology. It is obvious that Industrial Automation streamlines the operations in terms of speed, reliability and product output. In this thesis, welding fixture for two wheeler steering handle is modeled using CATIA software, forces are calculated, and an analysis has been carried out in the precisions placing of one circular component over another circular component during the welding process. Welding circular rod over another circular rod, the possibility of maintaining the accuracy in placing of curved surfaces is very less in the mass production. Here the difficulty is overcome by the new design of the fixture, and the angle as well as the linear movements is maintained in the accuracy of 0.1 mm without any robots. In the field of welding engineering where a consistently good quality, low cost with a maximum productivity is a must, this accuracy canbe done by without automation. Welding fixtures are available in different size, shapes, materials and mechanisms based on their need of operations. The precision of the fixture play a major role in the manufacturing component. Batch production is the commonly used method in various small and large industries. Welding a curved surface over an another curved surface is very challenging so is positioning the components. In mass production, positioning a job takes significant amount of time due to manual process. To overcome this challenge, theoretical approach has been carried out on the fixture like design fabrication and analysis.
