Abstract

An automatic submerged arc welding machine for the inner circular seam of a boiler, including a welding trolley, a welding power source, an electric control box, a welding wire reel, a flux tray, a welding cable and a control cable, the welding trolley is put into the boiler cylinder, and the welding trolley includes a welding torch, a wire feeding machine, flux hopper, horizontal adjustment slider, longitudinal adjustment slider, welding seam tracking device and walking trolley; the welding wire reel, welding power supply and electric control box are placed on the ground outside the boiler shell, and the welding wire in the welding wire reel passes through the boiler drum The small hole on the head is guided into the wire straightening mechanism on the wire feeder; the welding power supply passes the welding wire through the small hole on the drum head to connect with the welding wire terminal board on the welding torch, and the electric control box passes the control wire Pass through the small hole on the head of the drum and connect with the welding trolley. The invention can solve the problem that the last inner circular seam of the boiler shell assembly cannot be automatically welded.

Description

technical field [0001] The invention relates to a submerged arc automatic welding equipment, in particular to a submerged arc automatic welding trolley. Background technique [0002] The boiler shell is mainly composed of a cylindrical steel cylinder and two welded heads similar to spherical segments. The welding of the inner and outer ring seams of the combination of the first head and the cylinder can be completed with the help of the submerged arc welding operation frame and the rotating tire, while the inner ring seam of the combination of the second head and the cylinder can be completed with the submerged arc welding operation frame Automatic welding cannot be implemented because of the inability to reach into the barrel. For a long time, this inner ring seam can only be completed by manual manual arc welding. The disadvantage of manual welding is multi-layer and multi-pass welding, large welding deformation, long time consumption, low efficiency, and difficult to gua...
