Title: Improvements in or relating to welding
IPC: B23K11/11
Filed: 1932-03-14
Abstract: 381,471. Welding parts of road vehicles. BUDD INTERNATIONAL CORPORATION, 25th Street, Philadelphia, U.S.A.-(Assignees of Paugh, J. J. ; 2500, Hunting Park Avenue, Philadelphia, U.S.A.) March 14, 1932, No. 7495. Convention date, April 6, 1931. [Classes 83 (ii) and 83 (iv).] In a method of electric resistance welding overlapped metal sheets, such as the outer flanged panel of a sheet-metal door to flanges on the door rails, the electrodes are applied to the sheets in close proximity but under differential pressure so that the weld is effected in the vicinity of the electrode under the lower pressure. The weld is thus made without heating the metal of the outer side of the panel to fusing temperature and weld marks on this surface are thus avoided. In spot welding the flange a of the outer door panel b to the flange c of the door rail d, the parts are placed on a copper or like block 19 which rests on a rubber block 21 and is universally mounted by means of U-shaped copper or like strips 22 on a copper or like block 20 carried by a rod 23 adjustable in an extension 17 of a vertically adjustable arm 14. On the arm is pivoted at 26 an electrode 25 with a forked end 28, 29, between the forks of which moves the co-operating electrode 13, both electrodes engaging the same side of the work. The electrode 13 is adjustably secured in one of a pair of plates 32, 33 carried by a hollow slide 31. The slide is suspended from a headed rod 36, a spring 39 being mounted between the head of the slide and an adjustable nut 40 on the rod. The upper end of the rod is secured to a head 45 which is pivotally connected to a lever 42 pivoted at 43 and normally held in inoperative position by a spring 451. The electrode 13 is pressed down when the lever 42 is operated by a cam 46 rotated through reduction gearing and one revolution clutch from a motor 48. When the electrode 13 engages the work the welding pressure is obtained by the spring 39. Prior to effecting the weld the electrode 25 is pressed down with a pressure from two to six times that on the electrode 13 by springs 59 engaging between a cross-bar 56 secured to the electrode 25 and nuts 57 on links 52, which pass through the cross-bar and are connected to levers 51 having a cross-bar 55 resting on the lever 42 above the cam. When, as in Fig. 3, the panel flange a<1> is narrower than the rail flange c<1>, the forks 29 of the electrode 25 engage the rail flange directly.
