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
Applications
- Fossil Power Plant Construction/Maintenance
- Steam Generation Equipment Fabrication
- Nuclear Power Plant Construction/Maintenance
- Chemical Facility Construction/Maintenance
- Shipyard Construction
- Gas Transmission Pipelines
- Process Piping
Features
- WELD HEADS 800 SERIES 805, 810, 820, 830, 840, 860
- Collets for all tube sizes / fitting geometries
- Waterproof carry case standard
- Bench mount bracket
- Internal weld head cooling standard
- Convenient flip-up view port allows final inspection before welding
- Encoder motors provide precise, repeatable speed regulation
- “Jam� detection/protection. If rotation stops for any reason, it is instantly sensed and power to the motor is immediately interrupted.
- No more damaged motors or drive trains
- Standard 8 m (25’) hose pack length
- New rotation drive design tolerant of metal debris
- “Home� position switch automatically readies the head for removal following weld completion, and never requires adjustment
- Simple assembly makes field service straightforward
