Influence of scanning speed and defocus distance on laser welded PA6GF30/SUS444 dissimilar lap joints

•The weld seam of PA6GF30/SUS444 lap joint by laser welding was composed of melted zone and glass transition zone.•The tensile-shear force of the joint can be determined by the undecomposed zone width in the melted zone.•Mechanical anchorage and chemical bonding were the key factors for the joining...
