The use of new advanced high-strength (AHSS) steels is often constrained by the state of the art in related processing and fabrication technologies. These technologies are only beginning to encounter the requirements that these advanced materials bring. Typical examples are joining and, in particular, welding. The latter has a major effect on microstructure evolution and, in turn, on mechanical properties. A common concern is that welding is not at all suitable as the joining technique for a particular application. This is why an experiment has been carried out which involves laser welding of a high-strength Q-P-processed AHS steel. Its results suggest that, by combining these technologies, very good results can be achieved, particularly in components under dynamic loading.
