Abstract: This paper deals with the design and analysis of the welding fixture for the body of a stone crusher. A fixture is a work-holding or support device used in the manufacturing industry. Fixtures are used to securely locate (position in a specific location or orientation) and support the work, ensuring that all parts produced using the fixture will maintain conformity and interchange ability. Locating and supporting areas must usually be large and very sturdy in order to accommodate welding operations; strong clamps are also a requirement. The toggle clamps are generally used. The body of a stone crusher consists of various plates that have to be welded to each other with a specified tolerance and weld quality. The material used in the manufacture of different parts of body of a stone crusher is Mild steel which is one of the most commonly used materials in the field of fabrication. All the welding processes are carried out by CO2 welding to ensure the quality of weld is as per the requirement. We have modeled a weld fixture by using UNIGRAPHICS NX8.0 software which is one of the software used for modeling components in most of the design based industries. While the modeling of the components the material selection is carried out simultaneously based on the design considerations related to loads, etc. Later the stress concentration and deformation on the baseplate of the weld fixture have been found by applying certain load on the baseplate, using the Finite Element Analysis (FEA) by using ANSYS software that provides best output within few seconds. Finally the stress concentration and deformation results are presented in this document
