Preparation, Application Status and Development Trend of Titanium-based Brazing Filler Metals

Titanium-based filler metal has now become the preferred materials for brazing joining of titanium alloys or special superalloys. The application, welding methods of titanium alloys, technical advantages of brazing and research status of main brazing materials were systematically introduced. The development history of titanium-based filler metals and the advantages of titanium-based amorphous foil ribbon filler metals were summarized in detail. The preparation method of titanium-based powder filler metal and the preparation principle and process of amorphous foil ribbon filler metal were mainly analyzed. The application status of titanium-based filler metal in the field of titanium alloy heat sinks was listed. The development trend of new titanium-based filler metals was prospected.
