| Abstract: | The oxygen-natural gas cutting and welding technique for metal material were studied in this paper.The result indicated that the high cutting quality and high welding quality and efficiency can generally be obtained by means of designing high speed cutting spray nozzle and double-deck separate flow oxygen welding torch and adopting suitable cutting and welding process parameter and measure,and the cost is so lower that the method of oxygen-natural gas has a wide developing prospection in the future for the application comparing the technique of the oxyacetylene cutting and welding. |
