Lasers in Automotive Industry

The automotive industry has always been one of the driving forces behind innovative laser applications. Continuous further development of automobiles with special regard to performance, reduced fuel consumption and improved environmental friendliness employs millions of people around the world. Coherent-ROFIN has gained an outstanding reputation as a supplier of laser systems for the automotive industry. This is based on active support for our customers with regard to the optimization of existing production processes and the processing of new materials. Applications areas include material processing in high-tech segments such as Formula 1 as well as mass production of series vehicles. The automotive industry has stringent requirements regarding the quality and reliability of beam sources. In conjunction with cutting, welding and marking, lasers offer considerable benefits compared to conventional techniques. Improved flexibility and ease of automation, meet the central requirements of this sector.

The first lasers were used to weld simple cylindrical parts, such as the components of an automatic transmission. The use of a CO² laser minimized distortion allowing highly compact and affordable gear trains. Today, lasers are used to process complete vehicle bodies. Our solutions for connecting rods scribing to create notches or for microprocessing of fuel and air filters are used by the majority of leading automobile manufacturers and their suppliers. Roof seam, door welding, three-dimensional cutting of hydroformed parts, annealing of door springs, welding of cylinder head sealants or marking of day & night panels are only a few examples out of a wide range of applications.
