Welding Wind Turbine Towers

Steel Sections are Powder Welded
Powder welding outside Each tower section is welded with a seam lengthwise, plus a circular welding seam to connect to the next section of the tower. This is done by placing the tower sections on a rolling bed which slowly rotates the tower, while an operator with a powder welding machine welds the sections from the outside...

Powder welding inside ...and another operator welds a corresponding set of seams on the inside.

Checking Welding Seams for Safety
Welding seams in towers are checked using ultrasonic or x-ray devices. Important seams are checked 100%, while other seams are checked on a sample basis.

Notice: The Guided Tour on Wind Energy is mainly from the Danish Wind Industry Association Web Site: www.windpower.org , and we provide it here just for your reference,hoping you can get some useful information on wind energy!
