Abstract
The invention comprises continuously producing a pilot puddle (21) on the surface of the workpiece, spreading the pilot puddle to a preselected width (x) with a high intensity stream of oxygen gas, and impinging a stream of scarfing oxygen gas on the spread puddle the apparatus comprising a pilot oxygen nozzle (14) for producing the pilot puddle, a blowpipe (12) and a nozzle 9 being provided for producing the high intensity oxygen stream and the scarfing oxygen stream respectively. Ports (10, 16) supply fuel and oxygen to provide preheat flames. The invention enables spot scarfing to be effected without stopping the relative movement between the scarfing apparatus and the workpiece.
