The new diode-pumped disk and fiber lasers found much attention, recently. Both combine the main advantages of the conventional workhorses for laser welding: high efficiency like CO2 and short wavelength like Nd:YAG (enabling beam guiding through fibers). With these configurations solid state lasers with more than 1 kW of mean power reach to the focusability level of CO2 lasers, now. This contribution presents first results of welding metal sheets with these lasers. The advantages of strong focusability will be discussed in detail. Special attention will be given to high speed welding up to velocity values of more than 50 m/min.
