The invention belongs to the technical field of a
welding machine, and particularly relates to a creeping-type automatic tracking
seam welding machine, which is characterized in that: a
slide plate which can move transversely along a base is arranged on the base, a compression spring is arranged between the
slide plate and the base, the
slide plate is provided with a slide platform which moves longitudinally along the slide plate, a compression spring is arranged between the slide plate and the slide platform, the slide platform is provided with a
cantilever, one side on the outer end part of the
cantilever is provided with a roller which rolls along an annular seam of a work-piece to be welded, a
welding torch is arranged on the
cantilever at one side of the roller, a
joint line of centers of the
welding torch and of the roller is parallel to a
central line in the length direction of the cantilever, and one side of the line of centers of the
welding torch and the roller is provided with a press block or a press wheel for pressing one side welding element or an outer layer welding element. The automatic tracking
seam welding /
cutting manipulator has beneficial effects that: the automatic tracking
seam welding /
cutting manipulator has a simple structure and low production cost, is convenient to install, repair and use, can automatically track a seam trace to realize the movable welding, has high welding quality, and is suitable for seam welding annular weld seams.
