T Head 419

The T Weld Head 419 is capable of reproducing the precise motions of a skilled manual GTAW welder. It is specifically designed for multipass pipe welding applications and larger diameter/heavy wall applications requiring precise welding process control. Used with Pipemaster Power Source Models, this Weld Head improves productivity by increasing duty cycle, reducing repair rates and producing welds of consistent quality.

The Weld Head is mounted on the pipe by means of metal Guide Rings that are available for all standard pipe sizes. The Weld Head mounts entirely on one side of the joint, allowing use for pipe-to-fitting welds.

FLX-Track® allows long linear seam welds on flat or curved surfaces, such as tanks and vessels, as well as ID, OD, and compound curvature welds to be made. The track flexes to conform to different diameters, and uses either vacuum or magnet attachment. Mounting the Head on an oversize Guide Ring with adapter feet makes it possible to use on CrMo and other alloys that require preheating.
