REDISTRIBUTION OF ELEMENTS IN STEEL LASER WELD JOINT STUDIED WITH LASERINDUCED BREAKDOWN SPECTROSCOPY
Annotation
Redistribution of elements in joints of steel plates after laser welding is studied. Laser emission spectral analysis (LIBS) reveals the following trends of horizontal and vertical migration of alloying elements: Mn towards the front side of the weld joint, Al towards the back side with concentration at the central line. Dependences of the redistribution on welding type and parameters are studied.
