Description

technical field [0001] The invention relates to the field of welding technology, in particular to a flux bracket for submerged arc welding of pile pipes. Background technique [0002] In the offshore construction of the pile pipe, due to the thick wall and large diameter of the pile pipe, the welding workload is huge. However, at present, no matter at home or abroad, the welding of the pile pipe of the offshore oil platform jacket has been using manual arc welding for many years. Therefore, low-efficiency welding methods have restricted the development pace of the rapid growth of offshore oil platforms. [0003] As one of the important links in the fabrication of offshore steel structures, pile pipe construction is mainly affected by three factors: first, manual or semi-mechanized operation, which not only has low work efficiency, but also has high labor intensity. Second, because the offshore construction is greatly affected by the natural climate, the effective time of th...

Problems solved by technology

[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, it has increased labor intensity, production costs, and reduced the automation technology level, welding quality and efficiency of pile pipe welding.
