Abstract

1417328 Door panel HARRIS PREBLE CO 20 Feb 1973 [18 Dec 1972] 8343/73 Heading E1J [Also in Division B3] A panel for the door of a lift comprises a metal plate 112 at least 0.09 inches thick welded to a rectangular frame of angle metal, the frame including two reinforcement members 124, 126 of angle metal extending between the longer sides of the rectangle and stiffener members 128-132 fixed between the reinforcement members and the other sides of the rectangles The welding is preferably MIG welding and is carried out in a specified order to avoid problems produced by differential expansion of the plate 112 and frame. The frame is initially clamped to the plate 112 and then spot welded thereto at the points 1-32 in that order; next, the reinforcements are arc welded to the frame A-D and then spot welds 33-44, arc welds E-H and I-N and tack welds 45-62 are carried out. The face plate is preferably in contact with a heat sink, e.g. of copper or aluminium, during welding and may be further cooled by water or carbon dioxide. The inert gas may be 75% argon and 25% carbon dioxide.
