[Also in Division F2] A method of making bimetallic tubing comprises providing a ferrous base tube 10, alloying a layer of metal selected from zinc, tin, silver or aluminium on to a surface thereof, engaging a copper base tube 20 therewith with a surface of the copper tube adjacent the layer, mechanically altering the dimensions of the copper base tube so that the adjacent surfaces of the tubes abut and thereafter inductively heating the tubes to a temperature below their melting points and above that of the layer, whereby the metal of the layer alloys with the copper base tube and solidifies. The copper tubing 20 is fed with a ferrous strip 70, having a galvanized zinc layer in contact therewith, to forming rolls 72. The composite tubing thus formed is drawn by rollers 94, 96 or by clamps 52, 54 and puller 56 through a welding station including an induction heater 90 where the abutting edges of the strip are welded together leaving a small clearance between the tubes 10, 20. The tube 20 is drawn over a mandrel 32, which expands it into tight engagement with the tube 10, and an induction coil 40 heats the tubes to melt the zinc layer. The heated copper tube expands more than the steel tube to exert a high pressure thereon and as the zinc layer liquefies the copper starts to dissolve therein. In an alternative embodiment the copper tube is positioned over the coated ferrous tube and both tubes are pulled through a sinking die (110) prior to passing through a heating inductor (112), Fig. 4A (not shown). The alloying characteristics between the layer 12 and the sleeve 10 are enhanced if a fine powder of copper formed in a slurry is coated on the outer surface of the sleeve.
