Other AbstractThe invention relates to an arc oscillation-based gas shielded welding arc tracking method which comprises the following steps that after the welding is started, a welding gun starts doing a periodic oscillation along a direction vertical to a weld joint a current sensor carries out real-time sampling on a welding current sampled data is filtrated filtered data is subjected to deviation judgment and converted into deviation data and the deviation data is converted into a movement command, and a weld joint track is compensated in real time through a deviation rectifying device. Because sampled signals are filtered by adopting software, the arc oscillation-based gas shielded welding arc tracking method is high in response speed and tracking precision and due to the adoption of a dual-filtering mode, the signal mutation caused by instable arc is reduced, the deviation compensation dosage is calculated by using known welding parameters, the support of a database or expert system is not needed, the requirement of a welding device on a weldment processing precision is lowered, and thus the arc oscillation-based gas shielded welding arc tracking method is an effective means for realizing the flexible automatic welding.
