Laser Welding of EK-61 Powder Alloy Parts Produced by Direct Laser Growth
摘要
Abstract
The effect of laser welding conditions on the physicomechanical properties of parts made by direct laser growth from an EK-61 powder alloy is studied. The results of metallographic studies of the weld and the near-weld zone are presented. The possibility of formation of a high-quality weld by laser welding of such products is shown. The number of passes is found to affect the weld quality.
