概要
- 論文の詳細を見る
A novel freeform fabrication method for metals, named 3D Micro Welding (3DMW), has been developed. It is a combined process of the freeform fabrication system with TIG (Tungsten Inert Gas) welding. The formation of titanium micro beads was investigated with respect to the diameter, height, and contact angle on the titanium substrate as functions of arc discharge current and two different shielding gases. The Ar-4% H_2 gas was more effective in preventing oxidation of beads than Ar gas. Simple 3D titanium objects with arch, number and pyramidal shapes were formed. Needle form crystals of β-phase titanium precipitated in the α-phase titanium matrix doing bead formation by rapid cooling. The interface between a titanium bead and titanium substrate were joined well without cracks or pores.
