Abstract
This paper investigates the repair of damaged gear by using wire arc additive manufacturing. This study focuses on AISI 4340 type gear which is repaired. Single track depositions were used to identify the optimized parameter. The quality of single beads are affected by wire feed rate, current and voltage. The single beads were tested visually, tensile testing and SEM analysis. The AISI 4340 gear has a strength of 900 Mpa [4]. The optimized bead has 690 Mpa (75% of the original gear) from the tensile testing and the bead has shown no sign of cracks and presence of Micro-void coalescence in traces. The damaged part in the gear was rebuilded in the optimized parameter. Then wire cut EDM and grinding operation were done on the rebuilded part in order to get the original geometry [5]. Forvalidation a gear test rig was used to find the performance of gear under various loading conditions wear analysis.
