Abstract

1364892 Casting processes; welding by fusion LA SOUDURE ELECTRIQUE AUTOGENE PROCEDES ARCOS SA 16 July 1971 [24 Sept 1970] 51396/73 Divided out of 1364891 Headings B3F and B3R A method of making a wall for a pressure vessel comprises attaching a reinforcing sheet of metal 20 to a first layer 21 of metal and adding a second layer of metal to the surface of the reinforcing sheet by a welding process, the said second layer being added in a series of welding passes which are rectilinear and juxtaposed. In the embodiment shown in Fig. 2, a water-cooled copper bar 40 is placed against the surface of the metal plate 20 and a first bead 24 of metal deposited on the surface of the plate 20 by electroslag welding using a movable L-shaped mould 28, the arm of the mould over-lapping the bar 40. After completion of the first bead 24, further beads are deposited in a similar manner until a layer of metal of the required dimension has been built up. During the deposition of each bead the arm of the mould overlaps the previously deposited bead. Instead of using a starter bar 20, a channel shaped mould having a detachable side (41), Fig. 3 (not shown), maybe used. After the first bead has been deposited, the side 41 is removed to leave an L-shaped mould and the process continues as before. The length of each bead may be such that a layer of approximately circular shape is formed, copper bars (37) being placed at each end of each bead to prevent run-off of the molten metal, Fig. 4 (not shown). Instead of electroslag welding, submerged arc, plasma arc, metal arc inert gas or tungsten arc inert gas processes may be used to build-up the second metal layer. The bimetallic material forming the reinforcing sheet 20 and said first layer 21, may be roll-clad, explosion clad, vacuum brazed or otherwise mill clad.
