Welding Wind Turbine Towers

Steel Sections are Powder Welded
Powder welding outsideEach 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.
