磁控电弧传感器的细丝埋弧焊熔宽建模

In this paper, Based on magnetic control arc sensor model, established the mathematical model of magnetron arc sensor pool width which based on the Magnetic-controlled arc seam tracking system for submerged arc welding. Using the mathematical model to study the change rule of the pool width which was under the lateral alternation magnetic field. The main parameters in the model have been selected to be done experiment, and got the influence law of the pool width curve affect by excitation frequency and excitation current. The simulation results and actual welding test results are basically identical, the model which established in this paper is certain directive significance to the Magnetic-controlled arc seam tracking system for submerged arc welding.
