Abstract

543.532. Uniting by fusion. LINDE AIR PRODUCTS CO. March 14. 1941. No. 3484. Convention date, June 20. 1940. [Class 83 (iv)] In electric fusion welding by passing a current between the work and a fusible electrode having its end inserted into a mass of granular fusible mineral material, a column of this material is maintained above the welding puddle and surrounds the electrode so as to force the fused slag to flow radially outwards. Overheating of the electrode above the welding zone due to the tendency of the molten slag to build up around the electrode is thus avoided. An apparatus for making a rivet weld at C comprises a cylindrical casing D having an apertured horizontal plate 14 to which is secured a conical hopper 18 and an inner apertured cylindrical member 12, the plate 14 being spaced above the work so as to allow the molten slag S formed by melting the granular material to be pushed out radially by the column of granular material G which is continually supplied to the hopper. The member 12 is provided with a cap having a guide hole for the metal electrode E or an elongated slot so that the electrode may also be manipulated laterally of the weld. In a line welding apparatus the casing D is replaced by a pair of plates 52 provided with horizontal plates 56 and inclined hopper plates 60 and a pair of apertured members 54 on which may be secured a slotted horizontal plate to guide the electrode along the welding groove. Specification 433,723 is referred to.
