The 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.
