Hybrid Products from Laser Powder Bed Fusion Manufactured Inconel 718 and 316L Utilizing Laser Welding

Abstract:

Additive manufactured (AM) 316L and Inconel 718 (IN718) parts using laser powder bedfusion technique and the weldability of the mixed pair by laser welding was investigated in this paper.The effect of prior heat treatment of the materials was also taken in to consideration. The motivationbehind this work was to investigate if hybrid products could be manufactured from these materials formore costefficient production of AM products. The results showed good reliability of the welds asthe tensile results were on par with the 316L base material. The hardness of the weld fusion zone was50 HV lower compared to the 316L base material hardness at 225 HV. In general, the results showedlaser welding is a very promising method for joining these printed materials and can be utilized asanother tool when integrating these materials into a design.
