Abstract
A method is provided for teem-welding metals, preferably light metals, particularly aluminium and its alloys, in which the metal, during its introduction into a casting mould, is caused to form one or more metal jets which are directed as far as possible at right-angles to and concentrated against the surfaces to be melted of the workpiece or workpieces. There is used a mould of such volume and with such an arrangement of the workpiece or workpieces therein, that the desired melting is achieved with that quantity of metal which, as the process proceeds, accumulates in and fills the mould, which quantity constitutes all the metal introduced into the mould.
