15,396. Tunzelmann, G. W. de. June 28. Welding; brazing; working by electricity.-A metallic oxide or oxides, such as the oxides of iron, copper, lead, or manganese, are incorporated or mixed with the carbon to form the electrodes or carbons for use for electric welding, brazing, and like purposes. The object is to reduce the excess of free carbon in the arc, and also to produce an arc in which the heat is more equally diffused owing to the presence of a metallic vapour.
