The article assesses the strength and ductility of laser welded joints made of steel Strenx S700MC. The assessment was  based on tests results concerning the material structure, hardness as well as quasi-static and dynamic tensile tests. The dynamic tests were performed using the tensile split Hopkinson pressure bar technique and strain rates of 10³ s^-1. The obtained results revealed that the strength of joints under quasi-static and dynamic tensile test conditions were high and similar, yet their ductility significantly deteriorated under the impact load.
