摘　　要：针对铝合金薄板对接焊,采用双椭球热源分布模式,基于ANSYS软件平台,建立了运动电弧作用下焊接过程的有限元数值分析模型。在模拟的过程中,利用ANSYS软件的APDL语言,较好地模拟了焊接时焊接电弧移动加热过程以及整个温度场的瞬态变化,实现了参数化编程。对模拟的动态过程进行分析,得到了焊件温度场的分布规律,为以后焊接应力应变的准确分析奠定了基础。A double elliptic distribution model of moving heat-source was used to TIG welding of thin plato with aluminum alloy, and a 3-D non-linear FEM analysis model was established based on ANSYS software. Using APDL language of ANSYS software, the moving and heating course of welding arc and instantaneous change of the whole temperature field were simulated better on butt joint welding. The regulation of temperature field distribution was obtained by analing of the dynamic process simulation. Research resuRs are good for the analysis of welding stress and strain field further.
