Problems solved by technology

With the development of offshore oil development, the construction of offshore platforms has increased significantly, and with the extensive application of low-alloy high-strength steel, the requirements for welding quality have become higher and higher. Traditional welding methods are increasingly unable to adapt to this high-speed growing development needs
[0003] As one of the important links in the fabrication of offshore steel structures, pile pipe construction is mainly affected by three factors: one is manual or semi-mechanized operation, which not only has low work efficiency, but also has high labor intensity
Second, because offshore construction is greatly affected by the natural climate, the effective time of construction operations is very short. At the same time, various engineering ships are required to cooperate in the construction, and the project cost is very high.
[0004] Although the automatic welding currently used has replaced the original welding method and improved the welding efficiency of thick-walled pipes, however, with the rapid development of industrial production, the constraints of this link on production have gradually emerged. Welding quality and efficiency are low

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an automatic submerged arc welding device for pile pipes. Background technique [0002] With the rapid growth of my country's energy demand, the development of offshore oil and gas resources is becoming increasingly urgent. The development of offshore oil fields is inseparable from oil platforms. The current oil platforms are mainly jacket platforms, and the offshore installation of jackets is inseparable from piling and welding of pile pipes. Among them, due to the thick wall and large diameter of the pile pipe, the welding workload is huge, and the progress of the installation work mainly depends on the welding time. However, at present, no matter at home or abroad, for many years, due to the special offshore construction conditions and high technical quality requirements, the welding of offshore oil platform jacket pile pipes has been using manual arc welding. With the deve...
