D-Head 420
Orbital weld heads for seamless multi-pass GTAW pipe welding connections
Orbital Weld Head for Multipass GTAW Pipe Welding
The Magnatech D 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 welder. The D Weld Head is used for applications with radial and axial clearance constraints. Interchangeable guide rings provide mounting on the pipe, and allow the D Weld Head to cover a broad size range: 1�? - 14�?. The D Weld Head improves productivity by increasing duty cycle, reducing repair rates, and producing welds of consistent quality.
