Evaluation of the Effect of Focal Plane Position on the Penetration Depth in Laser Welding of High-strength Steel
DOI: 10.22184/1993-7296.FRos.2025.19.7.524.543
The article presents the results of laser welding of steel using the lenses with a focal length of 300, 500, 700 and 900 mm. The effect of focal plane position of laser radiation relative to the work surface of the welded plate on the weld penetration depth has been evaluated. The research is based on a series of experimental welding samples using the lenses with various focal lengths and controlled changes in the focal point relative to the welded plate surface. The results can be used to select the process modes for laser welding of thick high-strength steels and to develop recommendations for the equipment adjustment.
