Abstract

In a welding process (see Group XXII) the weld metal is provided by an aluminothermic composition containing aluminium and an oxidizing agent in substantially stoichiometric proportions, the oxidizing agent including iron oxide, for example:- .Iron millscale.74% .Aluminium (turnings).23% .Fluorspar.3% The crucible is lined with an alumino thermic mixture such as described in Specification 627,678, of which the following is an example:- ..Parts by wt .Aluminium.20 - 50 .Nitrate or chlorate.0 - 12 .Iron oxide or manganese di-. .oxide.0 - 15 .Fluoride.0.1- 10 .Binder.1 - 5 .Refractory filler.Balance to make 100 ..parts by wt The fluoride may be Na, K or Al fluoride, Na3AlF6, K3AlF6 or a complex fluoborate fluosilicate or fluotitanate, and the filler grog, sand, zircon or chamotte.
