| The Autocar. 15. x. 12. Soldering Aluminium. 1091 A special flux and solder for use with aluminium has been brought forward by the Alu-sol Manufacturing Co., Worcester Street, Wolverhampton. The solder and flux are made up and supplied together in the form of a paste, which is applied to the parts to be soldered after they have been cleaned by scraping. Heat is then applied by means of a spirit lamp (for small work), a blow lamp, Bunsen burner, or an acetylene and oxygen welding flame. The melting point of the composition is about half that of aluminium, and it is said that the process may be more correctly described as an autogenous weld. It is claimed that an aluminium alloy, or aluminium to any other metal, can be dealt with. Several samples of work by this flux and solder have been submitted to us, and in each case the joins appear to be very effective, and we are informed that joints made in October, 1910, which have been exposed to all weathers, are still intact. For repairing castings a special solder is supplied, the method of use being to apply flux and filings of the solder to the parts and then to pour molten aluminium into the cavity with a ladle. | ||
