What is BIW? BIW stands for Body in White. It is the stage in automobile manufacturing in which a car body's frame has been joined together, i.e. before painting&before motor, chassis sub assemblies or trim have been integrated to structure. Assembly involves variety of techniques: welding- spot and MIG MAG or friction, stir, riveting, clinching, bonding&laser brazing. The term "body in white" is thought to have originated from practice of painting car bodies white before they were fitted with the final trim. This was done to protect metal from corrosion & to make any defects in the finish more visible. BIW is a critical stage in the manufacturing process, as it determines the overall shape & structure of the car. The accuracy of the BIW assembly is essential for ensuring that the car is safe &performs as designed. In recent years, there has been a trend towards light weighting of BIWs. This is being done to improve fuel efficiency and reduce emissions. Some of the ways that BIWs are being made lighter include using high strength steels, aluminum &composite materials. BIW fixture design is the process of designing &manufacturing fixtures that are used to hold &locate car body components during welding, assembly &other manufacturing operations. Fixtures are essential for ensuring that car bodies are assembled accurately & consistently & they can also help to improve productivity and quality. I hope this helps!
