Design and Analysis of Welding Fixture for Elementary Weld Joints

Abstract

Fixtures are tools and contributes to increasing manufacturing efficiency and productivity. They are utilized in various manufacturing processes to rest, support and locate the workpiece. Welding fixtures are utilized in fabrication shops.  They are specifically utilized to hold and locate the metallic plates and piece parts for permanent joining. They appear simple in construction but to develop an effective welding fixture, deep knowledge of design and manufacturing is required. Welding fixtures can be under static load from the workpiece they are supporting as well as under thermal stresses due to heat liberated by the particular welding process. The purpose of this paper is to provide a model and analyze a compact welding fixture and to illustrate few weld joints for small metal plates. The same model can be utilized efficiently to weld metal plates with variations in dimensions within some range. Software used for modeling of parts is CATIA V5R20 and that for the analysis is ANSYS 16.0
