Good castability, machinability and a favourable damping capacity make cast iron materials most suited for car industry applications. Especially when welding high quantities or complex structures, these advantages are obviously, therefore cast iron materials are used mainly for producing parts for moving mechanisms, driving elements, gear-box components etc. Due to the good ductility properties of spheroidal graphite cast iron (GGG) and malleable cast iron (GTS), these materials are used especially for producing dynamically high-stress-resistant parts. In view of an appropriate material selection, the combination of the above-mentioned materials with steel components is increasingly gaining importance. One example is the use of weldable white-heart malleable cast iron (GTW-S) for welding structures, that are subject to high dynamical stress, e.g. a car tilted-shaft front axle. However, welding the clearly lower-priced spheroidal graphite cast iron (GGG) and black-heart malleable castings (GTS) also entails problems, so precautionary measures have to be taken. Especially when welding high quantities or when applied into automated production, laser beam welding features high potentials in regard to process speed and weld quality. The described investigation are about the suitability of the laser beam welding process for joining GGG- and GTS-materials with steel.
