Development of Linear Automation in Butt Joint Fixture to Enhance Welding Characteristics

Abstract

In today’s global economy, the survival of companies depends on their ability to innovate and improve quickly. Metal Inert Gas (MIG) welding can apply for many kinds of material such as mild steel, carbon steel, stainless steel, aluminum. This paper deals with the fabrication of MIG welding fixtures to clamp work piece and reduce the rejection ratio in production and reduce the welding distortion. The automation is used to welding the work piece for increasing the quality and production. Fixtures are essential components of the manufacturing process because they are required in most automated manufacturing, inspection, and assembly operations. The device is provided to support and control the work area with fixture providing a linear motion by the motor. Using fixing and automation welding often eliminates the need for verification, positioning, personal marking, and the same quality in the manufacturing process. These increase productivity and reduce operating time compared to manual welding. Automation welding process gives a best result compared to the manual welding. Some of the issues are occurred during manual welding (welding distortion, imperfect welding, less quality, and lower production rate). These problems can be solved by using automation welding process. In welding distortion, the automation rate of welding capacity increases 50% compared to manual welding rate. In imperfect welding joint, the fixture setup helps us to weld the work piece with 45% more efficiently.
