Problems solved by technology

[0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the single welding method for the wind power tower in the prior art. Because the annulus of the wind power tower is relatively large, the placement position in the conventional welding process is greatly affected by external forces, resulting in The welding quality of the overall weld seam is not uniform, the welding effect is poor, etc., so as to provide a ring welding method for wind power towers that can effectively improve the welding quality and reduce the influence of external factors

Embodiment Construction

[0026] Specific embodiments of the present invention will be described in detail below. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0027] Such as figure 1 As shown, the present invention provides a kind of ring welding method of wind power tower, comprising:

[0028] 1) Beveling: on the end face of the prefabricated ring of the wind power tower, the inner groove and the outer groove are alternately opened in sequence along the direction of the circular extension;

[0029] 2) Butt joint: pair and arrange a group of adjacent prefabricated rings of wind power towers so that the opposite inner grooves and outer grooves are correspondingly aligned;

[0030] 3) Welding: A group of adjacent inner grooves and outer grooves are welded at the same time to complete the sequential welding of multiple groups of inner grooves and outer grooves;

Abstract

The invention discloses a girth welding method for a wind power tower tube. The girth welding method comprises the steps of: (1) beveling, specifically, forming inner bevels and outer bevels sequentially and alternately in the end faces of prefabricated ring pieces of the wind power tower tube in the annular extending direction; (2) abutting, specifically, pairing one set of adjacent prefabricatedring pieces of the wind power tower tube, and thus enabling the opposite inner bevels and outer bevels to be correspondingly aligned; (3) welding, specifically, completing sequential welding of multiple sets of inner bevels and outer bevels by adopting a mode that a set of adjacent inner bevels and outer bevels are welded at the same time; and 4) polishing: specifically, polishing a welded weld joint. The girth welding method achieves the effects that the welding quality can be effectively improved, and the influence of external factors is reduced.

Description

technical field [0001] The invention relates to the field of wind power tower processing methods, in particular to a ring welding method for wind power towers. Background technique [0002] The wind power tower is the tower pole of wind power generation, which mainly plays a supporting role in the wind power generation unit and absorbs the vibration of the unit at the same time. [0003] The traditional welding method is to stack the prefabricated rings and place them horizontally, and then weld along the circular weld. However, this welding method often has a single processing form, and is greatly affected by external factors such as gravity during the processing process, which is easy to cause Poor weld seam welding effect, uneven welding quality, etc. Contents of the invention [0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the single welding method for the wind power tower in the prior art. Because the annulus of ...
