Abstract

1,268,044. Seaming. BRITISH OXYGEN CO. Ltd. 22 May, 1969 [29 May, 1968], No. 25742/68. Heading B5K. [Also in Division B3] In continuous seam or spot, T-joint or, as shown, lap joint, continuously-energized laser beam welding of metal or non-metal workpieces 4, 6, the power density of the beam 2 at the area of incidence on the first encountered workpiece 4 is arranged to be above a threshold level at which it heats the workpieces primarily by conduction and to be below a ceiling level at which it vaporizes the workpiece metal to such an extent that there is insufficient of said metal left to form a weld. The depth of the molten pool 8 produced is greater than the thickness of the workpiece 4 so that the pool extends into the workpiece 6. The width of the pool is less than its depth. The power density is determined by laser power output and/or beam focusing. In an example, a continuously-operated carbon dioxide laser of 400 W. output is used for continuous lap joint welding of two steel plates, each of 0.015 inch thickness. The pool 8 has a depth of three times its width. The incident power density exceeds 1 x 10<SP>4</SP> MWm-<SP>2</SP>.
