Description：
The wind tower is a conical tube shaped welding structure, each section is around 10 to 40m length. The sections is connected by a connecting flange and the top is installed with a wind generator. The welds of wind tower are mainly circumferential welds and longitudinal welds. Welding process always use GMAW or FCAW on root welding and SAW on fill and gap welding.
