Embodiment Construction

[0015] Such as figure 1 , 2 As shown, it is a structural schematic diagram of a pipe welding machine. The pipe welding machine is characterized in that it consists of a base plate 1, a rotating mechanism 2, a positioning plate 3, a vertical positioning device 4, a cable 5, a welding machine 6, a welding head 7, and a winding Line column 8, clamping device 9, handle 10 are formed.

[0016] Two positioning plates 3 are installed on both sides of the base plate 1 respectively, and two vertical positioning devices 4 are respectively installed on the upper ends of the two positioning plates 3. When the clamping device 9 clamps the pipe, the two vertical positioning devices 4 can clamp The female pipe at the lower end of the pipe is positioned to make the pipe more fixed.

[0017] The rotating mechanism 2 is installed on the bottom plate 1, the rotating mechanism 2 and the bottom plate 1 are in the shape of concentric arcs, the welding machine 6 is installed on the rotating mechan...

Abstract

The automatic welding process for long pipe joint in boiler pipe header seam features that the welding process includes the first manual argon arc welding for 2 or 3 dots each joint; subsequent fixing the long pipe welding machine head outside the joint with fixture; and automatic rotating welding with welding head aligned obliquely to the seam. The long pipe welding apparatus for the said technological process consists of base plate, rotating mechanism, positioning board, vertical locating unit, cable, welding machine, welding machine head,wire winding pin, fixture and handle. The present invention has the advantages of automatic operation, raised welding quality and high production efficiency.

Description

technical field [0001] The invention relates to an automatic welding process and device for long pipe joints of boiler headers, which can be used for welding long pipe joints of improved full-penetration grooves in the boiler manufacturing industry and other industrial production, and belongs to the field of welding technology. Background technique [0002] The welding technology and equipment level of power plant boiler components are relatively backward for the welding technology of the header, and the fillet welds of the long pipe joints of the header are welded by manual arc welding (SMAW). Because manual welding is greatly affected by human factors, the welding quality of fillet welds is unstable, and leakage accidents often occur. Contents of the invention [0003] The purpose of the present invention is to invent an automatic welding process and device for long pipe joints of boiler header. In order to achieve the above object, the technical solution of the present...
