ABSTRACT:
A steel material is treated by laser beams, in such a manner that the laser beams and a gas jet are concurrently projected to a working point of the steel material to produce a plasma around the working point and another gas jet is ejected to the working point at an oblique angle to the projecting direction of the laser beams so as to press the plasma against the steel material surface, whereby the form of the plasma can be controlled by changing the oblique angle of the another gas jet ejection.
