Influence Of Laser Hardening By Round, Profiled And Oscillating Beam On The Increase Of Service Life Of Machine Parts The developed technology of broadband laser hardening with a fibre laser beam using IPG 2D scanners will allow expanding the range of parts. The width of the hardening zone of 15–50 mm in one pass allows processing the seats of the centre shafts of various mechanisms and machines for rolling and sliding bearings. In addition, this technology can be used to strengthen bending and other dies with a depth of the hardened layer of 2.5 mm.
