Abstract
960,397. Making beams; welding by fusion; curving. BRODERNA HEDLUND A.B. Feb. 11, 1963 [Feb. 27, 1962; Dec. 13, 1962], No. 5540/63. Headings B3A, B3E and B3R. In a machine for welding one or more flanges to the web of a beam comprising supports for the web and flange and pressure means holding the flange against the web as the web and flange are fed to a welding zone, the pressure means is adjustable to vary the angle between the flange and the web. In this way the web and flange may be presented to the welding zone at such an angle that after the weld has cooled they are perpendicular. The web 34, Figs. 1 and 3, is supported on each side by a series of lower rollers 72 mounted in fixed bars 74 and a series of upper rollers 76 mounted in bars 78 movable vertically by fluid pressure rams 82. The flanges 32 are supported on vertically adjustable rollers 56 and are held down by rollers 92 controlled by fluid pressure runs 98. The flanges 32 are pressed inwardly by rollers 52, 54 driven by variable speed motors and inclined in the direction of feed to hold the flanges on the rollers 86. The rollers 52, 54 on each side are journalled in a common bracket 44, 46 each adjustable about a horizontal pivot 66 by a hand wheel 70 to vary the angle of the flanges 32. The brackets 44, 46 are pivoted to carriages 22, 24 running on transverse guides 18, 20 and moved towards and away from each other by a fluid pressure ram 36. Welding current is fed to the work by brushes 56 and the rollers 52, 54 nearest to the welding zone S. In a modification, Fig. 4, for welding beams having webs with non-parallel straight or curved edges one or more of the pressure rollers 52, 54 on one or both sides of the machine (as shown the end rollers 54a, 54b on one side of the machine) are journalled in mountings 100 pivotally attached to the brackets 44, 46. Fluid pressure rams 106 adjust the position of the rollers 54a, 54b to suit the profile of the web and the fluid pressure ram 36 is actuated to move the carriages 22, 24 as required.
