轴向外磁场作用下钨极氩弧焊电弧温度场的研究

摘要

The research object is TIG model in ex ternal longitudinal magnetic field. It solved mass e-quations, momentum equations, energy equations, electric current equations and magnetic field equations. Arc temperature distribution in external longitudinal magnetic field presented the hollow bell type. The an-ode was the double peaked temperature distributions.%以轴向外磁场作用下的钨极氩弧焊模型为研究对象，通过求解质量方程、动量方程、能量方程、电流连续方程和磁场方程，得到轴向外磁场作用下的钨极氩弧焊电弧温度场呈现中空的钟罩型，阳极表面呈现双峰温度分布。
