ABSTRACT:
Bulkwelding is disclosed in which a consummable electrically conductive electrode is fed to a weld zone, and electric current is caused to flow in the electrode thereby providing a magnetic field about the electrode, particles of magnetically responsive weld material are fed to the electrode which magnetically adhere to it, fluxing materials are fed to the weld zone, preferably in front and in back of the electrode and adhered weld particles, and the electrode with the particles of weld material magnetically adhered to it are fed through the flux to the weld zone where the electrode and particles are melted to form the weld. The rate of feeding the weld particles and the electrode are coordinated to provide any desired ratio of weld particles to electrode in the weld. Both methods and apparatus are disclosed.
The apparatus includes a feeder having a discharge nozzle made of a non-conductive material which includes passage means for the electrically conductive consummable electrode, containers for holding the fluxing material and the magnetically-responsive weld particles, passage means from the weld particle container for feeding them to the electrode while in the nozzle, and passage means for feeding flux to the weld zone about, and preferably in front and in back of, the electrode with the weld particles magnetically adhered to it. Means are provided for coordinating and varying the rate of feeding the weld particles with respect to the electrode for varying the ratio of weld particles to electrode and thus the composition of the weld. A number of other features are disclosed.
