Welding fixtures are designed for the components which are difficult to weld in a normal way or without any holding unit, because fixtures have a direct influence on product quality, productivity and cost of a component to be manufactured in the industry. This paper investigates about the fixture design for restraining the angular distortions during butt welding within supplementary angles of joints by considering all the welding factors like easy access to its welding area, cycle time, and availability of space for fixture and materials are selected as per functional requirements and based on design by considering the technique of DFMA (Design For Manufacture And Assembly) by providing proper provisions for swiveling of the fixture accordingly to fix jobs for required angles of welds of high precisions. And conclusions on various aspects about the welded joints (i.e. distortion, material properties, strength, productivity, safety etc.,) were obtained by carrying the welding process with and without fixture.
