摘要
薄板焊接是一种重要的焊接技术,焊接温度场分析是焊接数值模拟的重要内容。运用有限元方法对薄板焊接温度场进行数值计算,并分析焊接速度和焊接电流对温度场分布的影响。研究结果表明:随着焊接速度的增加,温度场最高温度降低,而随着焊接电流的增加,温度场最高温度升高。
The welding of steel sheet is an important kind of welding technique.The temperature field analysis of welding is the important content in welding numerical simulation.The temperature field of steel sheet welding is calcuated by finite element method,and the effect of welding velocity and welding current on temperature field distribution is analyzed in the paper.The results show： the highest temperature in the temperature field decreases with the increasing of welding velocity, and that the highest temperature in the temperature field increases with the increasing of welding current.
