Abstract

This paper describes the weldability of JIS S45C medium carbon steel (same material with KS SM45C and SAE 1045) for machine structural use by Nd:YAG laser. This material have a limitation to the industrial application in spite of good mechanical characteristics. This is due to its difficult welding work from high carbon contents. We therefore have investigated laser weldability of this material to extend the application of medium carbon steel. The results of this study provide application possibility of Nd:YAG laser welding for medium carbon steel.
