Cold cutting is a cutting method. It adopts technical means or methods that do not generate high temperature during the cutting process, so that the material to be cut maintains the original material characteristics, and the temperature during the cutting process does not change sharply. Generally, the temperature rise does not exceed 40 degrees Celsius.Friction cutting method: Generally use abrasive wheel saw blade to cut, the cooling process is used to reduce the temperature to achieve the effect of cold cutting; Cpld cutting method: cutting is used to perform the cutting operation, and the cooling process is used to reduce the temperature to achieve the effect of cold cutting; such as blade cutting.

There are many kinds of cold cutting tools, such as water-cooled saw blade cutting machine, water-cooled cutting saw, hydraulic water-cooled cutting saw, water cutting, wire cutting, etc. Many cutting tools can achieve the purpose of cold cutting operation; Contor welded tube cold cutting flying saw is a safe cutting using high speed steel or TCT saw blade. At present, it has become the mainstream product of sawing equipment on welded pipe production line. The sawing process is non-sparking, low noise and safety.
