Abstract
A portable inertia welder is mounted in a housing so as to afford both axial and rotational movement of a shaft with flywheel weights. Rotational motion is provided by a motor affixed to the drive shaft while axial motion is provided by means of a hydraulic housing mounted around said shaft. A chuck mounted to the shaft holds a first workpiece for rotational and axial displacement. Holding devices such as vacuum cups secure the welder to a second workpiece. A flash cutting tool and an appurtenance with a flash trap, welding flats, and an internally threaded bore are described.
