Objective
Coming from automotive applications, the potential for high strength steel grades to be applied in lightweight construction are more and more required in many industrial sectors as construction, agricultural machinery or shipbuilding industry. However, fundamental metallurgical facts cause these steels to be relatively difficult to weld.
The existing limitations, as insufficient fatigue strength caused e.g. by an extreme martensite formation, can be overcome by the use of appropriate welding methods combined with induction heating. Thus, an adaptation of weld seam properties to the base materials properties will be enabled. The project results are expected to lead to an increased use of high strength steels and to gain benefit of both cost saving and raw material saving aspects.
