D-Head Weldhead

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.



Orbital Welding Features:
