A portable friction welder that applies direct axial load to the workpieces via a rotating variable pressure hydraulic cylinder placed between the workpieces and a rotational device. The portable friction welder includes an interchangeable adapter configured to receive a fitting for a first workpiece, a variable pressure hydraulic cylinder with a front end and a rear end, and a rotational device positioned behind the rear end of the pressurizing device. The friction welder is configured to be driven by the rotational device, to be interconnected to a clamp assembly holding a second workpiece, and to effect a friction weld to first and second workpieces. The portable friction welder also includes a bearing housing, thrusts bearings, and a thrust collar. Spring washers may be installed in the front end of the hydraulic cylinder to maintain axial load across the bearing housing. An interchangeable adapter is removably connected with the thrust collar.
