Abstract
A soldering technique was developed for titanium and titanium alloy.As a heatsource, infrared radiation from a halogen lamp was used.Titanium, gold and silver base solders were evaluated.The conditions studied were;ambience, gap distance, heating time, location of solder, investing method, pre-heating temperature and wrought or cast test metal.The ultimate tensile strength of each soldered joint was evaluated with a universal testing machine.Under flushing argon gas ambience, titanium, gold and silver base solders were successful.However, only silver base solders were successful in atmospheric ambience.The gap distance was not significant up to 300μm.To ensure the solder joint, the investing method required pre-heating to 500℃ and pickling by acid.There was no significant difference between wrought and cast metal specimens.
