DESIGN AND FABRICATION OF WELDING FIXTURE FOR A SINGLE DOORFRAME

ABSTRACT

Mass production aims at high productivity to reduce unit cost and interchangeability to facilitate easy assembly. This necessitates production devices to increase the rate of manufacture and inspection devices to speed up the inspection procedure.

Production devices are generally work holders with / without tool guiding / setting arrangement. These are called jigs & fixtures. The advantages of welding fixtures in production are that increase in productivity, inter–changeability, operator fatigue reduction and cost reduction.

Fixtures hold the work pieces securely in correct position with respect to the welding / machine / cutter during operation. The effect of the clamping element – an integral part of the fixture gets a gets importance while implementing it in an operation.

Welding fixture that can serve better technically as well as economically will make a significant difference in production processes.
