T-Head Model 419

  • Function: multi-pass orbital GTAW pipe-to-pipe, pipe-to-fitting
  • Materials: carbon-based and exotic alloys
  • Power supply compatibility: Pipemaster 515 and Pipemaster 516

The Magnatech T-head 419 welding head is designed to make pipe-to-pipe and pipe-to-fitting welds. Its full function capabilities allow it to replicate all the motions of a skilled manual welder.

The T-Head 419 welding head is used for larger diameter/ heavy wall applications, requiring GTAW process. Interchangeable guide rings provide mounting on the pipe, allowing the welding head to cover a broad size range.

Mounting the head on an oversize guide ring with adaptor feet allows use on materials requiring preheat. In addition to welding pipe, the T Head 419 is also used for ID and OD welding on larger tanks, vessels, and ductwork. This versatility is made possible by a patented flexible track system, enabling stable installation on complex, curved surfaces.

The T-Head 419 welding head improves productivity by increasing duty cycle and reducing repair rates.

Designed for Demanding Applications
Whether you’re welding preheated CrMo pipes or performing complex welds on large tanks and ductwork, the T-Head Model 419 ensures consistent results with superior adaptability. Its customizable adaptors, heat-resistant design, and FLX-TRACK™ technology make it an essential tool for precision welding in challenging environments.

The Magnatech T-Head Model 419 redefines versatility and reliability in orbital welding, providing advanced solutions for projects requiring preheat resistance, curved surface adaptability, and high-precision performance.

REQUIRED ACCESSORIES

The guide rings are used to fix the welding head around the pipe and to allow accurate rotation of the head around it. Rotation of the welding head around the pipe is accomplished by a friction drive system, consisting of the powered V-rollers driving against the two V-belts, which are attached to the guide ring surface. Guide rings consist of two identical half sections that hinge open. They are available in 38 standard sizes.  Guide rings may be used on a smaller pipe diameter than what they are designed for by using adaptor foot kits (see the section below on adaptor foot kits).
