We studied on the high temperature brazing process of the titanium frame of spectacles using the tensile test apparatus. The titanium rods, 50 mm in length and 3 mm in diameter, were polished with #2000 emery paper and brazed using the high frequency induction brazing method. Morphologies and chemical compositions of pure titanium surface were observed using SEM and EDX. The chemical compositions were observed using AES in the brazed seam, brazed interface, base metal. The results obtained from this study were sumrnarized as follows. The tensile strength of titanium frame was measured 392.25 MPa at the brazing temperature 96o·c. The tensile strength of titanium frame was measured 398.65 MPa at the Ar gas injection speed 25 Q/min, temperature 96o·c. AES data for the brazed interface region showed that the diffusion of Ag, Cu and Zn occurred to the titanium.
