Abstract

1463630 Thermo-aluminic reactions; welding by fusion ELEKTRO-THERMIT GmbH 14 Nov 1975 [15 Nov 1974] 47124/75 Headings B3R and B3V [Also in Division E1] In a railway crossing-point frog an outwardly curved wall 4, Fig. 1, at the end of a longitudinal seam 3 between main and auxiliary members 1, 2 of the frog is performed by a thermo-aluminic process. The longitudinal seam 3 is welded by an automatic machine using a protective gas (CO 2 ) process. The curved part 4 is surrounded by mould halves 5, 6 each having a riser 7 and an air pipe (8), Fig. 2 (not shown). The parts 1, 2 are pre-heated before the thermo-aluminic reaction is started in a crucible 9.
