Technical Field
The invention relates to the technical field of welding parts, in particular to a welding gun stabilizing structure and an all-position automatic welding machine.
Background
In conventional welding processes, when referring to round tubes, particularly large diameter round tubes, conventional methods typically accomplish the weld by securing a welding gun and manually rotating the round tube. However, for large diameter round tubes, manual rotation can become difficult, and it is difficult to ensure consistency of the weld quality by manually welding the weld bead throughout the circumference.
In order to solve this problem, a new type of welding part has been developed on the market, which is provided with a rail outside the pipe, on which the welding part is mounted, and which can be welded around the pipe for one revolution. This design appears to solve the problem of manually rotating the tube, but in practice it exposes some problems.
In particular, since the weld itself is heavy, when it moves on the endless track, in particular to the side or bottom of the pipe, the track is liable to be deformed because it is not subjected to such weight. Once the track is deformed, the position of the end of the welding gun is shifted, resulting in a change in the distance between the welding gun and the weld. Such changes may directly affect the welding effect, may cause problems such as discontinuous weld, unevenness or even incomplete welding, and seriously reduce the quality of welding.
Thus, although such an apparatus for welding around pipe elements improves the degree of automation of welding to some extent, how to ensure stability of the rail and accuracy of movement of the welded portion on the rail remains a problem to be further studied and solved.
