外加磁场对激光焊接熔深的影响

Effect of outer magnetic field on laser beam welding penetration depth

摘要: 研究了外加磁场对激光焊接熔深的影响,结果表明,外加磁场对熔深存在一个最佳值,外加磁场达到该最佳值时,激光焊接熔深大大增加,当外加磁场过强或过弱时,熔深都有显著下降。

Abstract: The effect of outer magnetic field on the penetration depth during the process of laser beam welding has been studied. The results show that there is an optimal value of the outer magnetic field when the weld penetration depth reaches its maximum value.The penetration depth decreases obviously as the outer magnetic field is excessively strong or weak.
