Redesigned tool welds pipe ‘in-place’

Magnatech’s D-Head has proven itself as a rugged tool to automate pipe welding in the fabrication shop or for site welding applications. The compact weld head utilizes the GTAW process and is designed for making circumferential butt welds where the pipe cannot be rotated. Only 50mm of radial clearance between pipes is required, allowing use for applications difficult to weld manually because of access. The redesigned head incorporates all necessary functions required for multi-pass welding including high speed, arc gap control, filler wire feed

capability, torch rotation, endpoint ‘dwell’, and torch oscillation with adjustable stroke width. While many orbital weld heads are limited to very finite size ranges, the D-Head can be used on any size of pipe or tube from 25mm up to 355.6mm. Therefore, one weld head can cover a broad size range, by changing only one component – the guide ring. Guide rings are available for all standard ‘boiler tube’ sizes. A contractor can purchase the equipment for a specific job, knowing that it can be used for future jobs as well.

The D-Head is designed for use with Magnatech’s new digital power supplies. The D-Head mounts on only one side of the weld joint. Pipe-to-fitting welds can be made as simply as pipe-to-pipe welds. The water-cooled head can be used on pipe alloys requiring preheat. The D-Head is capable of substantially increasing productivity by increasing the duty cycle of the welding process. Users have reported increased welding production by a factor of 2-3 as compared to manual welding. The weld head can be used in any gravity position.

Users can choose from one of three forms to enter weld programs, including automatic weld schedule programming. The M200’s automatic shield gas control (patent pending) simplifies set-up of shielding gas, requiring no use of a separate flow meter. Universal voltage input (100 to 230 V [ac]) requires only a cord/plug change to accommodate an input voltage. The M200 works with all currently available Swagelok weld heads, and includes four USB ports, Ethernet port, USB device (output) port, VGA output, and serial port.
