Steel pipe annular welding device with welding seam detection function

Abstract

The invention discloses a steel pipe annular welding device with a welding seam detection function, and belongs to the technical field of steel pipe welding. The steel pipe annular welding device withthe welding seam detection function comprises an operation table and a pair of limiting mechanisms installed at the front end and the rear end of the upper side of the operation table, a pair of arc-shaped cavities corresponding to the limiting mechanisms in position are formed in the operation table, the top ends of the pair of arc-shaped cavities penetrate through the upper end of the operationtable, and driving gears are rotationally installed in the pair of arc-shaped cavities correspondingly. By arranging the pair of limiting mechanisms capable of automatically rotating, a steel pipe isarranged in the limiting mechanisms in a sleeved mode, and the steel pipe is fixed through the clamping mechanisms in the limiting mechanisms; the limited steel pipe can automatically rotate, and seam welding after spot welding can be easily completed without manual operation; and after welding is completed, quality detection is conducted on the inner side and the outer side of the welding position of the steel pipe through an inner and outer welding seam detection mechanism, inner and outer synchronous detection of the welding seam position is effectively achieved, the operation is easy andconvenient, and the flexibility is high.

Description

technical field [0001] The invention relates to the technical field of steel pipe welding, and more specifically, relates to a steel pipe annular welding device with a weld seam detection function. Background technique [0002] In the process of construction and use, steel pipes often need to be connected with flanges, and then realize the connection between multiple steel pipes and between steel pipes and other equipment. During the welding process of traditional steel pipes, the flange and the steel pipe are generally spot-welded manually, and then the gap between the flange and the steel pipe is welded. [0003] However, the steel pipe is large in size and heavy. When welding, since the solder joints are in the circular direction, whether it is spot welding or seam welding, technicians are often required to rotate the steel pipe, which is difficult to work. The efficiency is low, and it is difficult to meet the welding of large quantities of steel pipes; in addition, in ...

Problems solved by technology

[0003] However, the steel pipe is large in size and heavy. When welding, since the solder joints are in the circular direction, whether it is spot welding or seam welding, technicians are often required to rotate the steel pipe, which is difficult to work. The efficiency is low, and it is difficult to meet the welding of large quantities of steel pipes; in addition, in the prior art, after the steel pipes are welded, in order to improve the welding quality, it is necessary to detect the welds, and the existing detection equipment needs to be carried out along the circular position of the weld Circular detection, that is, it is necessary to detect the outer end of the weld and the inner end of the weld, often requires step-by-step detection, the operation is cumbersome, and it is difficult to realize the simultaneous detection of the inside and outside of the weld
