ABSTRACT:
A method of simultaneously cutting and welding metal, especially relatively thin sheets of metal, utilizing laser energy. The invention uses surface tension in the globule created at the site of the impingement of the laser beam on the work to form finished edges on both sides of the line of cut. A laser beam surrounded by a thin shield of inert gas is used, the gas removing some of the molten metal but leaving sufficient to form the beads which comprise the finished edges on both sides of the cut, and also preventing oxidation of the beads.
