Abstract: The paper presents the evaluation of weldability of unalloyed high
strength heat-treated steels using of a laser beam welding robotic station. The
key factors and properties affecting the usability of the aforesaid welding technology
when welding the above-named steels were identified on the basis of the
assessment of the microstructure and the measurements of hardness distribution
in the related butt welded joints.
