Abstract
966,207. Welding by fusion. H. ROSORIUS, [trading as HERMAN ROSORIUS INGENIEURBURO]. Oct. 29, 1962 [Oct. 28, 1961], No. 40806/62. Heading B3R. An expanding mandrel for welding operations comprises two sets of guide rails which are movable radially of the longitudinal axis of the mandrel, the welding position being between the two sets of guide rails, and a shaft on which a sleeve is displaceable longitudinally to expand a set or sets. Rails 8 are moved out radially, to engage the inside wall of a tube, by withdrawing a shaft 1 into a sleeve 2 by turning a hand wheel 4 on a threaded section of the shaft 1. The rails 8 are connected by links 7 to a member 5, fast with the shaft 1, and by links 10 to a member 13 fast on the sleeve. Rails 24 are similarly connected by links 21 to a member 15, fast on the sleeve 2, and by links 26 to a member 16 slidable on the sleeve 2 and abutting a tubular member 17 itself slidable on the sleeve 2 and bearing, through a ring 19, against the hand wheel 4. The rails 24 are held fast while the rails 8 are expanded. When the rails 8 have engaged a tube, the rails 24 are allowed to move out radially to engage and centre a flange to be welded to the tube, continued rotation of the hand wheel 4 moving the tubular member 17 axially to effect such expansion. Both sets of rails 8 and 24 may be expanded simultaneously if neither set is held.
