Abstract
A spiral steel silo has become the preferred choice for building steel silos because of its short construction period, low cost, and high strength. Owing to the harsh outdoor welding conditions of the spiral steel silo and the high risk of manual welding, in this paper, an automatic welding robot is proposed, and its key technology is studied. The welding process parameters consisted of welding voltage, current, and the distance between the conductive nozzle and the base material, which were determined through experiments. The key technology of seam tracking on the roof of a spiral steel silo was studied. Finally, a weld bead tracking experiment and prototype welding experiment were carried out. The results suggest that the prototype can track the weld bead stably and accurately, and the welding effect can meet welding process requirements when the welding current is 200 A, the voltage is 20 V, and the distance between the welding nozzle and the base material is 12 mm.
