Abstract

A laser beam, in combination with a stream of oxygen, is directed at the surface of the insulation covering a conductor wire. The insulation is ignited and the subsequent combustion removes the insulation from the required area of the wire. The laser can be pulsed to provide the correct amount of heat energy. By moving the laser beam within the envelope of the gas stream, different areas of the insulation can be removed. Two alternative arrangements are shown. In drawing 1 the laser beam is outside the gas envelope except in the region of the surface of the insulation. In drawing 2 the laser beam extends fully within the gas envelope. The method can be used to remove any combustible material from a noncombustible substrate.
