The Penetration Shape Control Based on Dynaimic Energy Equilibrium During Arc Welding-Ⅰ.Analysis of Factors Effect on Penetration shape Following to the Principle of Dynamic Energy Equilibium

Li Liangyu; Geng Zheng; Cheng Shujun; Yin Shuyuan(National Key Laboratory of Advanced Welding Production Technology, HIT)  
The idea of dynamic energy equilibrium of the molten pool in order to achieve stable peneation is put forward, the factors having effect on peneation steadiness is explained with the concept of thermal resistance and thermal capacitance in a similar way of an electricity model.
