| 摘 要： | 针对奥氏体不锈钢ＴＩＧ焊接时，与电极同轴的单个轴对称空心圆柱线圈在双向脉冲矩形励磁电流作用下产生的间歇交变纵向磁场，采用无瑕点单积分磁场的数学模型，对ＴＩＧ焊外加间歇交变纵向磁场进行了数值计算，该方法具有模型简单，计算速度快和精度高等优点，在此基础上，讨论了该间歇交变纵向磁场的分布，磁场的均匀性及其纵向分量与横向分量的比率等规律，为深入研究外加磁场对ＴＩＧ焊的影响奠定了良好的基础。

| Abstract: | A non singular single integral mathematical model is applied to calculate the external intermittent and alternative longitudinal magnetic field induced by a single axisymmetrical and cylindrical hollow coil. The coil is coaxial with the reference electrode and excitated by a revisable pulsed current of square wave. Austenitic stainless steel is used for the TIG welding. Numerical calculation are made to obtain the magnetic field distribution and equalisation and ratio of traverse and axial branch of the external magnetic field. |
