Seam guidance

Focussed on your success

MNV stands for mechanical seam tracking and is a tactile seam guidance system.

A particularly robust and EMC-safe seam guidance system has been created by deliberately dispensing with servomotor drives.

The MNV is able to compensate for robot track and weld seam contour deviations of up to ±15 mm (vertically and horizontally). The seam contour is scanned in a tactile manner using guide elements that are optimally adapted to the respective welding task.

The guide element of the MNV is also the wire guide nozzle. Guiding the wire in a hardened nozzle permits very precise positioning of the wire.

An edge (e.g. a overlap joint) is required to guide the welding torch. The clamping forces are set using pneumatic cylinders.

Advantages

By using just mechanical components, the seam tracking system is not affected by electrical interference (ignition, earthing path, etc.).

Mechanical guidance means contamination has no effect.

To move to the start of the seam, the MNV01 can be centred horizontally by means of pneumatic cylinders. The vertical centre position of the MNV01 is detected via a light barrier.

If the guide edge at the end of the weld seam is no longer present, the MNV01 can be pneumatically secured in both axes
