Double-rail welding system

Abstract

The invention discloses a double-rail welding system which comprises a first rail, a second rail, a third rail and a fourth rail. The second rail is detachably mounted on the second side of the welding seam of the workpiece; the first track and the second track are both installed on the fixing support, and the fixing support can drive the first track and the second track to move; the first track and the second track are each provided with at least one welding trolley. The image acquisition component is used for acquiring an image of the to-be-welded part; the welding seam scanning device is used for obtaining welding seam morphology; and a control system. According to the double-rail welding system, the welding efficiency can be effectively improved, automatic identification, automatic planning and automatic welding of the welding seams are achieved, the automation degree is improved, the labor intensity is effectively reduced, and the welding precision is improved.

Description

technical field [0001] The invention relates to the field of pipeline welding equipment, in particular to a double-track welding system. Background technique [0002] With the peak period of oil and gas long-distance pipeline construction and the advent of the era of intelligent welding of long-distance pipelines, the transformation and upgrading of pipeline welding systems is very important. [0003] In the prior art, when welding long-distance pipelines, the procedures used include: opening a groove; welding the root of the groove; heat welding the groove; filling the groove three times; butt welding The seam surface is covered by welding; in the prior art, the time required for each process is long, and if each process needs to be heated, the welding efficiency is further reduced. [0004] In addition, in the existing technology, the external welding equipment for on-site construction requires artificial auxiliary operations during welding, such as wire cutting before we...

Problems solved by technology

[0003] In the prior art, when welding long-distance pipelines, the procedures used include: opening a groove; welding the root of the groove; heat welding the groove; filling the groove three times; butt welding seam surface for cover welding; in the prior art, the time required for each process is long, and if each process needs to be heated, the welding efficiency will be further reduced

[0004] In addition, in the existing technology, the external welding equipment for on-site construction requires artificial auxiliary operations during welding, such as wire cutting before welding, gas testing, orbiting, heating, fine-tuning during welding, and grinding of upper and lower joints. The requirements are relatively high, the workload is heavy, and the efficiency is low; at the same time, the pre-weld heating and temperature measurement of the pipeline before welding and during the welding process need to be manually operated, and it is easy to be negligent and inactive, resulting in a decline in welding quality
