Dross is one of the common problems in the plasma cutting process. It refers to the residue formed by solidifying in the cutting gap because the molten metal is not completely removed. During the plasma cutting process, due to the influence of cutting parameters, equipment quality, material surface conditions and other factors, the phenomenon of slag hanging may occur.
If there is too much slag or it cannot be removed, it will affect the cutting quality and even lead to cutting failure. Therefore, in practical applications, corresponding measures need to be taken according to specific conditions, such as adjusting cutting parameters, cleaning cutting tools, replacing cutting nozzles, etc., to reduce the occurrence of slag hanging.
