Abstract
Abstract A method for processing materials with laser beams. A laser beam is directed against the object which is to be cut, welded or joined. A generated stream of air is directed over the object so that cooling air passes over the immediate area or location at which the laser beam strikes. The combination of the directed laser beam and the air stream is such that the cut or welded joint is left free from scorching or surface deformation due to overheating and burning.
