Abstract
The present invention relates to a method and device for cutting a workpiece made from a high chromium material such as stainless steel. The device comprises a processing head to irradiate and focus a laser beam onto a workpiece, a nozzle connected to the processing head for spraying and assisting gas onto the workpiece, a storage tank for storing a carbonate, and an orifice device for drawing carbonate from the storage tank so that it may be fed into the nozzle and sprayed onto the workpiece with the assisting gas. The addition of carbonate to the assist gas prevents excess dross from adhering to the cut surface of the workpiece.
