PURPOSE:To make easy the brazing of titanium materials to each other by subjecting the titanium material parts to heating and vacuum treatment then brazing the parts in a gaseous argon atmosphere and subjecting further the brazed parts to a strengthening treatment in gaseous hydrogen, nitrogen, etc. CONSTITUTION:The titanium material parts formed to the shape of spectacles are subjected to the vacuum treatment under heating at 300-1,000 deg.C in a furnace. The titanium parts are put into another vacuum chamber and gaseous argon is filled therein where the joint parts of the parts are brazed. The brazed titanium spectacles are subjected to the strengthening treatment at the joint parts by heating at <=500 deg.C in the furnace filled therein with the gaseous mixture composed of hydrogen, oxygen, argon, nitrogen, etc. or the single gas. The joining of the titanium material parts to each which is heretofore difficult is made easy by the above-mentioned method.
