Abstract
409,631. Making boiler drums &c. MANNESMANNROHREN-WERKE, 1B, Berger Ufer, D³sseldorf, Germanv. Dec. 15, 1933, No. 35384. Convention date, Jan. 27. [Class 83 (ii).] In making fusion welded hollow bodies, particularly of large diameter and with thick walls such as boiler drums and other pressure vessels, the sheets are first bent and the edges, which remain straight during bending, Fig. 4, are fusion welded by autogenous or electric welding with welding rods or electrodes and are then heated and the edges rounded and the burr reduced by hammering or pressing into the form shown in Fig. 5. The parts may be heated in a gas fire and hammering or pressing effected intermittently or continuously. A water gas roll welding machine may be used to heat and press the edges.
