CRAWLER RUNNING TYPE AUTOMATIC WELDING EQUIPMENT

PROBLEM TO BE SOLVED: To automatize the overhead position welding for a huge object. SOLUTION: Running crawlers 2A, 2B capable of respectively sucking to the outer plate of a hull and moreover respectively controlling the running speed are arranged in both sides of a running body 1, the welding torch 3 freely shiftable in the left and right directions is equipped in the middle part of the running body 1, sensors 21A, 21B detecting the weld line are arrange in the forth part and back part of the running body 1, the inclined angle of the weld line to the running body central line of the running body 1 and the shift quantity of the welding torch 3 from the running body central line are operated based on detecting signals from the forward censor 21A and the backward sensor 21B, and the main controller 5, controlling the position of the welding torch 3 and controlling the running speed of the left and right running crawlers 2A, 2B so that the inclined angle and the shift quantity become zero respectively, is provided.
