Tubesheet Weld Head 425

The Tubesheet Weld Head 425 is specifically designed for fast and simple operation.  With the possibility for fusion welding as well as wire feeding, combined with Arc Voltage Control (AVC) for multipass welding and watercooling, this Tubesheet Weld Head provides you with all the latest technology available for tube sheet welding.

Multiple torch positioning adjustments allow virtually all tubesheet joint designs to be welded.

For welds requiring filler wire addition, the wire feeder is mounted on the Weld Head and uses a standard wire spool. This wire feeder provides way more precise and positive wire feeding, compared to floor-mounted feeders for tubesheet Weld Heads.

With the Magnatech Tubesheet Weld Heads, you bring productivity and repetitive precision of machine welding to the fabrication and repair of steam generators and heat exchangers.
