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.The entry side of the sample refers to the side which corresponds to point where the beam first interacts with the sample or the start of the weld. The exit side of the sample conversely refers to the side which corresponds to point of lastanbsp;...
