Magnatech D-Head 420 GTAW Orbital Pipe, Multi-Pass 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: 25 – 356 mm. The D Weld Head improves productivity by increasing duty cycle, reducing repair rates, and producing welds of consistent quality.
