| Abstract: | The welding characteristic of Ti/Al dissimilar alloy by laser welding-brazing with assistant current was investigated. The experiment results indicate that laser power has a significant influence on mechanical properties and interfacial microstructures. The assistant current effectively decreases laser power required for joining Al alloy to Ti alloy, and significantly enhances the melting of filler wire and Al substrate as well as the wettability of liquid metal on Ti substrate. In addition, the interfacial reaction is improved by increasing assistant current to some degree. |
| Keywords: | laser welding-brazing assistant current Ti/Al dissimilar alloy interfacial reaction |
