摘　　要：钨极氩弧焊接中,焊枪起夹持钨极、输送氩气和传导电流的作用。焊接时,电弧、熔池的温度辐射以及电流的电阻热导致焊枪温升,影响了焊接质量、焊接效率以及焊枪的使用寿命。对管板焊接过程中焊枪的散热进行的数值模拟及对宽间距厚翅片与窄间距薄翅片两种结构的散热效果进行的对比分析,找出二者散热效果的差异,确定窄间距薄翅片的散热结构和散热效率方面更好。In the process of TIG welding,the torch is used to hold the tungsten electrode,transport argon and conduct current.During welding,the temperature radiation of arc and molten pool and the resistance heat of current lead to the temperature rise of welding gun,which affects the welding quality,welding efficiency and the service life of welding gun.Numerical simulation of heat dissipation of welding gun in tube-sheet welding process and comparative analysis of heat dissipation effect of wide spacing thick fin and narrow spacing thin fin are carried out to find out the difference of heat dissipation effect between the two structures,and it is better to determine the heat dissipation structure and heat dissipation efficiency of thin fin with narrow spacing.
