In recent years, cutting the development and application of technology has been developed by leaps and bounds, cutting technology has shifted from the traditional oxyacetylene flame cutting into the development of new industrial gas flame cutting, plasma arc cutting, laser cutting, water jet cutting, and other energy sources, a variety of Methods of modern technology, cutting technology, modern control technology at the same time again and cutting technology to combine research and development of a new generation of automated cutting machines.

近年来，切割技术的开发和应用取得了长足的发展，切割技术已经从传统的氧乙炔火焰切割发展成为新型工业燃气火焰切割、等离子弧切割、激光切割、水射流切割等多能源、多种工艺方法在内的现代化切割技术，与此同时又将现代化控制技术与切割技术想结合，研究开发出新一代的全自动切割设备。

14 If using oxyacetylene flame to cut welded fixture on alloy steel pipeline, shall cut at the point 3mm away from surface of the pipeline, and then grind the surface with grinding wheel.

7.2.14 当采用怕氧乙炔焰切割合金管钢管道上的焊接卡具时，应在离管道表面 3mm 处切割，然后用砂轮进行修磨。

When compressed air as plasma gas enthalpy value of the high arc voltage than 100V, power supply voltage of 200V or more30mm thickness of the cut the following materials, have been replaced by an oxyacetylene flame cutting trend.

压缩空气作离子气时热焓值高，弧压100V以上，电源电压200V以上，在切割30mm以下厚度的材料时，已有取代氧乙炔焰切割的趋势。

The artical puts forward the corresponding technical transform of the Oxygen-acetylene cutting and welding equipment-with liquid gas instead of acetylene.
