Welding of Low-Alloy Steels with Fiber Laser in the Mode of Beam Scanning

Аннотация

Metallographic studies and mechanical tests of welded joints formed by a fiber laser in the mode beam scanning in two passes are performed. The laws of formation of the joint, the process of laser beam welding in the mode of scanning, and the effect of the thermal action of the second welding pass on the metal of the weld are described. The process of laser welding with beam scanning is shown to have advantages.
