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.

Options
- TILT AVC (Adjustable) allows torch to be pivoted up to 60° for socket/fillet welds. Maintains arc length correction motion along tungsten electrode axis.
- GUIDE RING ADAPTOR KITS allow Guide Rings to be used on smaller pipe sizes. Use with oversized Guide Rings on preheated pipe to prevent heat damage.
- VIDEO ARC MONITORING Various configurations allow remote operation
- LOW PROFILE SPOOL KIT reduces radial profile of D Weld Head to 50mm (2”); Low Profile Wire Spool 0.5kg (1lb.) required.
