Friction Plug Welding
The I-STIR™ Plug Welding System is a proven solution for completing closeout self-reacting welds and repairing defective weldments. Engineered to deliver maximum flexibility, our custom plug welding machine solutions can be equipped to perform both friction push and pull plug welding.
A Complete Friction Plug Welding Solution
The I-STIR Plug Welding System (PWS) from PAR Systems is a complete integrated friction plug welding solution, featuring:
- Precision I-STIR controls, instrumentation, and software
- Proven independent forge actuator technology
- Reliable I-STIR hydraulic power unit and hydraulic service manifold
- Optional multiple degree of freedom weld head manipulator
Perform Friction Push and Pull Plug Welding
The I-STIR PWS from PAR Systems is a complete integrated friction plug welding solution, featuring:
- Friction Push Plug Welding: A preferred technique for closing self-reacting weld keyholes and repairing defective welds. After a heating phase, a rotating tapered plug is forced into a tapered hole until a preprogrammed distance is achieved.
- Friction Pull Plug Welding: Well suited when access is limited primarily to interior surfaces for any filtering or support required for the process. After a heating phase, a rotating tapered plug is pulled into a straight hole until a pre-programed distance is achieved.
In both applications, after the plug preprogrammed distance is achieved, plug rotation is stopped very quickly, and force maintained while the materials cool down. Excess plug material and back side extrusion are then removed.
