摘要
Abstract
Keyhole gas tungsten arc welding torch was chosen as the studied object. A 3 -D mathematic model was developed according to the theory of magnetic fluid dynamics,the K-T1G welding arc and the protecting gases in the K-T1G welding torch was stimulated and analysed using FLUENT software. The temperature,velocity of the plasma,potential and arc pressure distributions of K-TIG welding torch were obtained. The results can be used to guide K-TIG welding torch design,welding process control and welding quality evaluation ,etc.关键词
