基于动态能量平衡模式的弧焊熔透成形控制──Ⅰ.动态能量平衡模式的弧焊熔透成形影响因素分析

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

提出了控制熔池动态热输入与热输出的能量平衡以保证熔透成形稳定的思想，引入热阻与热容等概念，应用类似电模型的方法，较好地解释了焊接过程中影响熔造成形的因素，对熔透成形的控制具有一定的理论价值．

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.
