Embodiment Construction

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below.

[0015] According to the welding process of three-dimensional segmentation of pile legs provided by the present invention, the three-dimensional segmentation of the pile legs is large closing; the above-mentioned welding process includes the following steps:

[0016] (1) Weld the butt weld between the rack plates at the same time;

[0017] (2) Weld the butt welds between the four side plates at the same time;

[0018] (3) Weld the butt welds between the stiffeners on the rack plate.

[0019] The mechanical strength and precision of the pile legs can be improved by adopting the welding process of three-dimensional segmented and large closing of the pile legs provided by the invention.

[0020] Pay attention to the following welding work:

[0021] (1) Each welding seam should be welded continuously as much as possible. If it is necessary to stop midway, ...

Abstract

The invention discloses a welding process for pile leg stereo sectional erection, comprising the following steps: (1) welding butt welds between the rack plates at the same time; (2) welding butt welds between four side plates at the same time; and (3) welding butt welds between stiffeners of rack plates. The welding process for pile leg stereo sectional erection, provided by the invention, can improve the mechanical strength and the precision of pile legs.

Description

technical field [0001] The invention relates to a welding process, in particular to a welding process for three-dimensional segmented and large closing of pile legs. Background technique [0002] The offshore windmill installation ship is a new ship designed with the concept of turning conventional ship transportation, self-propelled and offshore platform jack-up, crane ship lifting and other multi-ship functions into one ship independently, and is mainly used for offshore wind turbines. Transportation and hoisting. That is, the ship is loaded with wind power generation equipment, sailed to the operating sea area, and completed precise positioning. The leg control system lifts the hull into an offshore working platform, which is lifted and installed by two cranes on the deck. [0003] When the offshore windmill installation ship is working, it is necessary to insert the legs of the windmill installation ship into the seabed. The stability of the legs of the windmill instal...
