Method of making welded joints between metals of different heat conductivity, and which have a tendency to form intermetallic phases when contacted at high temperatures, such for example as titanium and copper, and titanium and iron. The metal of the better heat conductivity is preheated and the other metal is protected from premature heating by an inert gas stream. Both metals are separated from each other during preheating and that portion ahead of the welding zone. |
