AO Series Pipe Heads

 

AO5 pipe welding head

Pipe / pipe weld head series is divided into AO series-opening welding head

In industrial manufacturing welding, there are a lot of the actual needs of orbital welding that the work piece can not be rotated, but by rotation welding torch to achieve, AO series of open type welding head precisely to achieve this purpose.

The main function

  •  The main part of the head made ​​of aluminum, lightweight structure, caliper clamping can be adjusted for different diameters.
  •  Clearance-free gear design, smooth rotation, low inertia and high temperature in a small environment, without jamming.
  •  For AO welding head also increase the arc length and the yaw system, which is important for thick-walled tube welding.
  •  Mechanical cam guide, so that tungsten can be kept constant from the surface of the work piece.
  •  The torch can also weld pipe / flange, tube / welding head, and special pipe / tube butt welding.
