Abstract

An experimental investigation into the cutting of mild steel up to 20 mm thick was carried out using a 2.5 kW CO₂ laser with a good quality T.E.M. 00 mode. The results show that cutting was possible in sections up to 20 mm although the quality of the cut edge decays between 15 and 20 mm. Explanations of this decay in quality and of the reduction in cutting efficiency with increasing thickness are put forward concerning the effect of the cut slot depth on the action of the oxygen jet. The technical and commercial possibility of cutting a stack of two or three layers of steel at once was investigated. This method was found to be less efficient than single sheet cutting.
