NDT of Rating Impact of Laser Padding on the Surface Layer

Title variants
Languages of publication
The article presents the problem of quality control the paramagnetic material of weld overlays laser made on ferro- and paramagnetic materials (steels, cast iron). To assess the quality of weld overlays paramagnetic material, and also the impact of overheating, besides laboratory researches on Keyence optical microscope, used measurement of existing magnetization of magnetic field distribution. Examples of test results by magnetic memory of metals are presented. It has been found, that is expedient use magnetic methods to assess the quality the microstructure of laser pad welded surface layer (influence of heat generation, microstructure changes, chemical composition and own stresses).
