Abstract

A portable welder (210) which is capable of being carried by a human operator for friction welding a first workpiece (e.g. a fitting) to a second workpiece (e.g. a valve packing housing) includes a lightweight hydropneumatic actuator (230) which produces a direct axial thrust upon an air motor (240). The air motor produces a direct axial thrust and a rotational drive upon a spindle. The spindle produces a direct axial thrust and a rotational drive upon the first workpiece. The actuator, air motor and spindle are contained within a housing. A clamp base (264) is made integral with the housing. With this arrangement the pounds force produced by the actuator will be equivalent to the pounds force translated between the fitting and the valve packing housing less any minimal decrease due to drag.
