Abstract
Abstract A welded corner construction for e.g., an assembled open frame comprising end and side members, e.g., angle-irons, said corner including a bracket comprising a pair of generally flat plates in general triangular form. The plates are welded together by means of welding projections which enter slots in the ends of each angle iron. In a modification, there is an upstanding flange on one of said plates at the exterior surfaces of said angle-irons, said flange covering the corner rendering the same rounded.
