Abstract: 648,664. Uniting by fusion. BENSON, L. E., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Nov. 3, 1948, No. 28571. [Class 83 (iv)] The abutting surfaces F of two plates A and B to be welded together are formed with passages G to permit the escape of gases generated during welding without passing through the molten weld metal, said passages being formed by narrow vertical or criss-cross grooves or by small nodules and the grooves or nodules being produced on one or both abutting faces F, prior to the welding operation, by machining, knurling or other means. The passages are directly effective only for the first run of welding metal but by reducing blow-holes and cracks in the first run, they reduce the transference of these defects to subsequent runs. The weld may be completed by another run along the undersurface. In a stepped joint, aligned passages are provided on both the horizontal and vertical steps of the joint and, if grooves for the reception of welding metal are provided both above and below the abutting surfaces, the passages extend between the two grooves.
