Developments in hybridisation and combined laser beam welding technologies

The laser welding process is the most flexible fusion welding process industrially available. The degree of flexibility is further enhanced and process limits are expanded if hybridisation or combination techniques are applied. After a general introduction of various related concepts, the enhancement of welding capabilities is illustrated in more detail by the state-of-the-art and latest advancements in laser-MAG (metal active gas) hybrid welding of up to 25 mm thick high-strength steel components. In addition, the manufacturing benefits of integrated cutting and welding with a multifunctional laser combi-head are described.
