Weight reduction, improved collision safety, and lower production costs of cars come in lockstep with the current requirements of global environment preservation. Advanced technology has met these demanding criteria with the development of the 'tailored blank', a process that achives weight reduction and higher collision safety by joining steel sheets of different thickness with the help of laser welding. Although laser welding has been in wide use, it is extremely difficult to maintain and improve the accuracy of the tailored blank and its formability which greatly influence processing quality. We count as one among the mere handful of manufacturers worldwide capable of producing engine-supporting structural parts consisting of compounds of different thickness.
Joining different materials by means of welding is another example. A welding technique for joining steel and aluminum, two entirely different materials, is used for the engine push rod: mastering this technique was once deemed impossible. |
