埋弧焊磁控电弧焊缝跟踪系统中传感器磁场的ANSYS模拟

imed at the problem of extra transverse field by the magnetic control arc sensor exciting in submerged arc welding seam tracking system, Finite Element Method was adopted, set up the computing model of the transverse field of magnetic control arc sensor, and ANSYS in order to simulate the transverse field in the study. Distribution of longitudinal section of transverse field in magnetic control arc sensor and magnetic density vector were both analyzed; the consistency of simulated value and measured value on magnetic induction density were verified, and the deviation of simulated result were tested; exciting current influenced the welding arc the state of motion also were researched.
