Plug Welder

The I-STIR Plug Welding System is a proven solution for self-reacting welds and for repairing defective weldments.

Product/System Uses

This system is a proven effective, reliable solution for closing self-reacting weld key holes, and for repairing defective friction stir and fusion weldments, especially where access is limited to exterior surfaces. Engineered to deliver maximum flexibility, it can be readily equipped to perform both friction, push and pull plug welding.

Friction plug welding is an extremely dynamic and quickly occurring event. Tight control of the spindle stopping process and plug indicated runout are critical for achieving consistent plug weld quality.

Capacity Handling

Push Plug Welding

After the heating phase, a rotating tapered plug is forced into a tapered hole until a preprogrammed distance is reached. Plug rotation is then quickly stopped and force is maintained while the materials cool down. Excess plug material and back side extrusion are then removed.

Pull Plug Welding

Again, after a heating phase, a rotating tapered plug is pulled into a straight hole until a preprogrammed distance is reached. Plug rotation is then stopped quickly and force is maintained while materials cool down. Excess plug material and back side extrusion are then removed.
