T Head 419

Orbital Weld Head For Multipass GTAW Pipe Welding

 

The Magnatech T model weld head is designed to make pipe-to-pipe and pipe-to-fitting welds. It is “full function� – with the capability of reproducing all the motions of a skilled manual welder. The T Head is used for larger diameter/
heavy wall applications, requiring the precise weld process control of gas tungsten arc welding. Interchangeable guide rings provide mounting on the pipe, and allow the T Head to cover a broad size range. The T model weld head improves productivity by increasing duty cycle and reducing repair rates.

 FLX-TRACK™
In addition to welding pipe, the T Head is also used for ID and OD welding on larger tanks, vessels, and ductwork.

  • Flexible track allows mounting on complex curved surfaces
  • Standard 2.3m (7.5') Track sections bolt together for longer lengths
  • Magnetic or Vacuum attachment
