Wind tower manufacturing can be so perfect and efficient

With the continuous deepening understanding of environmental issues and improvement of renewable energy comprehensive utilization technology, wind power generation has become a new trend in electric field construction due to its high power generation capacity, large installed capacity, and stable operation.

Welding and cutting is the main factor affecting the production of wind tower section

These tasks occupy the most of the production time. In the process of striving to improve the productivity of wind tower manufacturing, how to improve productivity and welding and cutting quality has becomes the most concerned by all wind tower manufacturers. There are several important steps in the manufacturing process of the wind tower section shown below:

1.1 Cutting

In the process of manufacturing the wind tower, first of all, the steel plate should be cut according to the requirements of the tapered section, and then the edge portion is cut according to the welding requirements. The traditional cutting often has many steps with high cost and low efficiency.

1.2 Longitudinal girth welding

Considering the shape of the welding seam and the welding speed, SAW submerged arc welding with higher deposition rate has become the first choice for the process used in the manufacture of wind towers. SAW (Single Wire Submerged Arc Welding): The traditional process of longitudinal and girth welding of towers, with a deposition rate of<15kg / h, has been gradually replaced. Tandem SAW (double electric double wire submerged arc welding): In double electric double wire submerged arc welding, two welding wires are simultaneously connected to their respective welding power sources, and are simultaneously fed to the welding wire by the wire feeding device, and the high deposition rate reaches 18- 22kg / h. Although the goal is to obtain a fairly round welded tank, the wind tower section usually has a slight deviation from the ideal shape, and this deviation will cause the tank to slide horizontally when rotating. Since the welding equipment is generally kept stable by the welding crane, a welding seam tracking system must be used to measure any movement of the workpiece and automatically adjust the welding.

1.3 Team-up Turning Roll

In the field of wind tower manufacturing, Fengwei Machinery has the world's leading equipment technology and high experience in producing tank turning rolls, which can be described as the preferred partner of wind tower manufacturers.
