Abstract

The invention discloses a welding process applying submerged automatic arc welding to a wind power generation tower foundation seat, belonging to the technical field of a wind power generation tower processing technique, comprising the following implementing steps: a, opening a K-shaped groove on the cylindrical section of a wind power generation tower, the groove angle outside the cylindrical section is 40-50 degrees, and the groove angle inside the cylindrical section is 30-40 degrees; b, assembling a flange of the cylindrical section and the wind power generation tower, forming an external circular seam at the groove between the external side of the cylindrical section and the flange, forming an internal circular seam at the groove between the internal side of the cylindrical section and the flange, and pointing welding the external circular seam; c, back welding the internal side circular seam for one time by utilizing carbon dioxide solid welding wire; d, welding the external circular seam by submerged automatic arc welding; and e, welding the internal circular seam by submerged automatic arc welding. The welding process of the invention solves the technical problems of large material consumption and low production efficiency when the wind power generation tower foundation seat is welded, and can be widely applied to the machining process of the wind power generation tower.

Description

technical field [0001] The invention relates to the technical field of wind power generation tower processing technology, in particular to a welding process applied to welding the base of a wind power generation tower. Background technique [0002] In recent years, with the continuous development of our company's wind power tower market, the wind power tower project has gradually become one of the pillar industries of our company. Submerged arc welding has been widely used in the construction of wind power towers and played an important role. The base of the wind power tower is made by butt-welding the cylinder joint and the flange. Since the weld joint is in the form of a T-joint, the traditional welding method is as follows: figure 1 As shown, a single-sided V-shaped groove is made on the inner side of the barrel section of the wind power tower, and the groove angle is 50 degrees. Then, the barrel section and the flange are assembled by submerged arc automatic welding. The...
