The new technology in the automotive industry by using tailor welded blanks YAN Qi Abstract: Tailor welded blanks are defined as two or more sheets of blanks with equal or different thickness, strength, or surface coatings welded together before forming process in the automotive workshop. Using tailor welded blanks in the body-in-white structure can obviously reduce the weight of the car and reduce the material scraps in the workshop. Compared with the traditional cars, the energy consumption of cars with tailor welded blanks is reduced. The application of tailor welded blanks in the automobile industry has brought more chances for the car manufacturers and more benefits for the customers. In this paper, the history and benefits using tailor welded blanks in the automotive industry are discussed in details. Keywords: Tailor welded blanks, Energy consumption, Automotive industry 0 Introduction With the improvement of the living standard, more and more people are using cars as their traffic tools, so more cars are manufactured in the world and as a result, a lot of problems are generated thereafter. Energy consumption is becoming the top one problem. The more weight of the car, the more energy is consumed. Therefore, the automotive industry is consistently striving for new ways to reduce the weight of car bodies but without weakening structural stability. One of the most successful approaches to achieve significant weight reduction, while improving the structure safety, is the application of tailor welded blanks. During the period of 1993 ～1997, ULSAB (Ultra Light Steel Auto Body) project organized by 35 steel plants and automobile manufacturers just promoted the application of tailor welded blank in the BIW (body-in-white) structure parts.
