The increasing demands for material performance and welding productivity have driven new advances in welding process and filler materials. This presentation will showcase some of the main research directions and results that relate to welding of automotive materials and the energy sector such as pipelines and nuclear materials in the past year. For example, the use of laser welding to join advance high strength steels with low melting point braze materials has allowed excellent surface finish to be achieved in thin sheet joints. Also, the use of wobble laser welding was shown to improve alloy mixing in thick section joints. Future research directions will also be discussed as they relate to the nuclear energy sector.
