    Some found information:
    The tower of a typical American-made turbine is approximately 80 feet tall and weighs about 19,000 pounds.
    A typical nacelle for a current turbine weighs approximately 22,000 pounds.
    The sections they build up here are for turbines that are well over 200ft tall, with cells that weigh 120-140,000lbs.

    Call 1.800.real.welder to find a qualified professional.
    There is one for a home about 2 miles from my house, it is about 20 feet tall and is 12" sch 80 pipe, is one 20 foot piece of pipe. There are 3 props 10 foot long.
    Looks like the base is plate welded with 7024 jet rod, same with the slip-on flange at the top.
    Hope this helps out and this has been 1.800.real.welder at your service.
    Sincerely,

    Here is some info on the first wind farm in the Abilene, TX area. This farm was built 15 or more years ago. Since then, literally hundreds of towers have been built around here.

    Exactly. A new member (1st post) asks a stupid question and all kinds of answers are put forth. He is just a troll. His screen name alone was enough for me not to answer.

    Default How they weld wind turbines

    Funnily enough i used to weld them together, here is how it was done:

    1) Sheet steel would be placed into giant hydraulic rollers and rolled up to form a "can" that was tack welded along the lengh and then a root weld put in it once it was checked, that weld was with a Mig welder.

    2) Once we had 2 "cans" you would already have 1 can on a set of wheels that turn both ways and was controlled with a pendant. We would have the 2nd can on a "c" hook on an overhead crane, it would be lowered into place. The fitters would then use heavy duty hydraulic jacks and also weld grips onto the can in order to have something for the jacks to push against. Pretty much the can were pushed by the jacks into place and also you could turn the wheels the can were resting on to manipulate these into posistion.

    3) Once the cans were together correctly (4mm fault tollerance) a root weld was put on the inside.

    4) The wheels the cans were resting were below a giant welding machine called a "sub-merged" arc welder. These would have 8mm wire and weld at 650-700amps. So the cans would sit on the wheels and turn and then once ready you start the sub arc, obvious the circle welds would be done first and on the outside.

    5) After a couple of sections were completed the weld would be tested by ultra sound equipment, issues would have to be air arced out or grinded out and redone by usually hand held mig.

    Some of the thicker cans had to be preheated before welding as the heat would dissipate too quickly. I think that there is more modern equipment available now to do this but this was back in 2005 when i welded my last turbine.
