Description
Automatic joint tracking system for most joint types
The GMH joint tracking controller together with ESAB servo slides and a sensor unit forms a robust and easy to use joint tracking system for automatic welding.
The GMH system minimizes repair welding and adjustments after welding with the arc always in the optimal position. The general quality will be kept on an even level and the operator does not need to focus on the weld head and its position. The operator can then keep an eye on the entire installation and contribute to a non-interrupted welding production by adding flux and prepare for changing the wire spool well in advance.
The welding head is mounted on a motorized double servo slide where the head can be moved up-down and left-right. The sensor is the most vital part in the system which gives information to the control system how to adjust the slides to keep the arc in the optimal position. There are a number of different mechanical sense fingers for different applications. Inductive sensors can also be used.
The operator uses the joystick to guide the welding head and mechanical sensor finger into correct position. No programming is required. The unit is set in track mode and the welding can start. Curved details can be welded fully automatic with GMH as the guiding tool, as long as they are within the working range of the servo slides.
GMH is available in two versions:
- With control panel on the front
- With remote control (no control panel on the front)
- Easy to use, no programming required
- Robust
- Flexible with a remote control
- Very short set-up times
- Gives a less stressful environment for the operator
- Minimize operator errors
