BIW (Body in White) is the stage in automobile manufacturing in which a car body's frame is attached together, in other words before painting and before the motor, chassis subassemblies, or trim (glass, door locks and handles, seats, upholstery, electronics, etc.) have been integrated into the body's structure. To assemble an item, there are different techniques that can be used, including welding (spot, MIG/MAG), riveting, clinching, bonding, and laser brazing. The term is derived from the practice of manufacturing automobiles before the development of steel monocoque structures - when automobile bodies were made by outside firms and attached to There is a separate chassis with an engine, suspension, and bumpers attached to it. A wooden frame would be bolted onto a wooden body (with a thin layer of non-structural metal on the outside) which was built by the manufacturers. Prior to the final colour being applied to the bodies, the bodies were painted white. There is a folk etymology for the phrase "body in white" which refers to the appearance of a car body after it has been dipped in a white bath of primer (undercoat paint) in spite of the primer's actual gray colour. In addition to this, BIW could also refer to when a car body is made out of wood - all timber products, such as furniture, etc., are considered to be "in the white" when they are at the raw stage before they are finished or varnished. It is in the "body in white" phase of car design that the final contours of the body of the car are worked out, in preparation for the ordering of the expensive production stamping die, which is the last step in the design process. Before a clay model from the design studio can be turned into a vehicle ready for production, extensive computer simulations of crashworthiness, manufacturability, and automotive aerodynamics are required in order to prove its crash-worthiness. A factory can sell BIW cars to racers, who can then replace up to 90% of the parts with aftermarket parts. Niche manufacturers like Automobile start their cars with BIWs from other manufacturers. The BIW Welding Fixture Design is frequently used in the automobile industry for welding purposes. It refers to the body or shell of a vehicle before adding components. Our range is highly demanded because of superior quality materials.
BIW Fixtures:
The Body in White refers to the welded sheet metal components which form the vehicle's structure to which other components will be attached. For example, the engine, chassis, exterior, and interior trim.

Welding Machines
Metals and thermoplastics are joined by welding by melting them together and allowing them to cool, causing fusion. The base metal (parent metal) does not melt during welding, unlike brazing and soldering.
A filler material is usually added to the joint along with the base metal. This forms a pool of molten material that cools and forms a joint that can be stronger than the base material, depending on the weld configuration. A weld may also be produced by using pressure as well as heat, or by using pressure alone if heat is not available. It is also necessary to use a form of shield during welding to prevent the filler metals or melted metals from being contaminated or oxidized as a result of the welding process.
Gas flames (chemical), electric arcs (electrical), lasers, electron beams, friction, and ultrasound can all be used for welding. A welding process can take place in a variety of environments, including open air, underwater, and in outer space. The welding process is undertaking. Precautious be taken to avoid burns, electric shock, vision damage, poisonous gases, and ultraviolet radiation exposure.
Prior to the 19th century, the only welding process was forge welding, which blacksmiths have used for millennia to join iron and steel. Later in the century, arc welding and oxy-fuel welding were invented, followed by electric resistance welding. In the early 20th century, welding technology advanced rapidly with the advent of world wars. It was during these wars that several modern welding techniques developed, including shielded metal arc welding, one of the most popular, and semi-automatic and automatic welding processes like gas It is possible to weld metal arcs, submerged arcs, flux-cored arcs, and electros lags using metal arc welding.
Later in the century, laser beam welding, electron beam welding , magnetic pulse welding , and friction stir welding were introduced. Researchers are developing new welding methods and understanding weld quality as science progresses, and robot welding is commonplace in industrial settings.
