Description

technical field

[0001] The invention relates to welding equipment and a working method, in particular to a universal automatic TIG welding tool for a water pipe robot and a welding method thereof. Background technique

[0002] With the rapid development of the economy, the pipeline transportation of various liquids or gases is more and more widely used. As one of the main functional parts of pipeline transportation, the lifting pipe has high requirements for its tightness and pressure resistance. The butt welding quality of the middle pipe of the water pipe and the flanges at both ends is the key to the quality of the water pipe, and will directly affect the performance of the entire pipeline transportation system. For a single piece of water pipe, in the process of butt welding the round pipe and the flanges at both ends, the coaxiality between the round pipe and the flange needs to be good, that is, the gap between the outer wall of the round pipe and the inner wall of the...

Examples

Embodiment 1

[0049] A general automatic TIG welding tool for a water pipe robot, used for welding a water pipe assembly 5, the structure of the water pipe assembly 5 is as follows Figure 4A , Figure 4B As shown, it is composed of flanges 51 at the upper and lower ends and a round pipe 52 in the middle. 8mm. The welding process of this welding tool is as follows: first weld a flange 51 and a round pipe 52 at one end on a set of this welding tool without a plug-in mechanism to form a semi-finished workpiece of a water pipe assembly 5, that is, the welded flange in the previous process 53, and then the welded flange 53 in the previous process is grasped by a fully automatic truss gripper and rotated 180° in space, and transferred to another set of this welding tool with a plug-in pin mechanism, and placed on the new welding tool The other end flange 51 groups are butt-welded into the finished workpiece of the water pipe assembly 5. The diameter of the center hole of the flange of the wat...

Embodiment 2

[0077] The support plate 17 of the welding table is provided with six mounting holes 171 for flange positioning pins. All the other are with embodiment 1.
