The automotive industry requires high precision and dimensional accuracy in Body-in-White (BIW) assembly operations to ensure product quality, structural stability, and manufacturing efficiency. During welding operations, improper positioning and inadequate clamping may lead to dimensional variations, deformation, and welding defects. Therefore, the development of a rigid and reliable welding fixture is essential to maintain assembly accuracy and improve production consistency. The present work focuses on the design and finite element analysis of a Front Floor Body-in-White (BIW) welding fixture used in automotive manufacturing applications. Initially, detailed study of the front floor assembly geometry, welding sequence, locating requirements, and manufacturing constraints was carried out. The fixture design was developed using the 3-2-1 locating principle to restrict all six degrees of freedom of the workpiece and ensure accurate positioning during welding operations. The complete fixture assembly, including base unit, clamp unit, riser unit, pin unit, and support structures, was modeled using CATIA V5 software. During the design process, important factors such as weld gun accessibility, manufacturability, structural rigidity, assembly tolerance, operator safety, and ease of maintenance were considered.
KEYWORDS
In the modern automotive industry, the manufacturing of Body in White (BIW) structures requires high dimensional accuracy, repeatability, and production efficiency. The front floor assembly of a vehicle is one of the most critical structural components because it supports the cabin structure, seat mounting points, and load transfer paths. During welding operations, improper positioning or inadequate clamping of the front floor panel can lead to dimensional deviations, distortion, residual stresses, and assembly errors. These defects directly affect vehicle quality, safety. 2.6. Objective 1. To study the geometry, welding sequence, load paths, and locating requirements of the Front Floor BIW assembly. 2. To design and develop the Front Floor BIW welding fixture and create its 3D CAD assembly in CATIA V5. 3. To perform finite element analysis (FEA) of the welding fixture using ANSYS software to evaluate stress, deformation, and structural rigidity under working conditions.
