A laser assisted welding technique has been used to repair failures that are representative of the cracks formed on die casting dies. Welding parameters and conditions were optimized to prevent longitudinal center fine cracking. The processed region was characterized for hardness, microstructure, composition and mechanical properties.Laser Welding: Is the process where a laser beam is used to fuse two materials in contact to form a bond. ... substrate properties are modified by melting or heating the surface and introducing appropriate alloying elements into the melt pool.
