In numerous applications, contradictory properties are demanded from welded joints; for example, high seam strength and good formability or high hardness value and wear resistance with the highest possible toughness. Controlling the solidification behaviour by means of seeding the molten weld metal represents a very effective method of fulfilling such contrary demands. For this purpose, seeding methods were modified for welding technology in such a way that microstructures can be specified. The choice of seeding materials is based on a theoretical model which describes the functioning mode of complex inoculants in a melt. The effectiveness of the procedure was investigated on ferritic chromium-steels by using various seeding methods and complex inoculants. Moreover, pronounced seeding effects were verified on nickel based superalloys and titanium. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
