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.
