Laser Welding Of Dissimilar High Carbon Content Materials

The difficulties encountered in welding two high carbon content materials are well known. If used properly, laser technology may provide new approaches for their solution. Due to persistent difficulty in welding C-43 shafts and C-33 wings, in particular, research was extended to determine the feasibility of these parts being laser welded. The troublespots were soon found to originate in a number of basic phenomena, as illustrated in this paper. Findings so far have been encouraging and, we feel, throw new light on both welding procedure and associated laser welding phenomena.
