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.

GMH
The GMH system minimizes repair welding and adjustments after welding thanks so that the arc is 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.

System contents
The welding head is mounted on a motorised 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.

Operation
The operator uses the joystick to guide the welding head and mechanical sensor finger into correct position. No programming at all is required. The unit is set in track mode and the welding can start.

Curved details can as long as they are within the working range of the servo slides be welded fully automatic with GMH as the guiding tool.
