Machining & Welding Road Milling Machine Hydraulic Cylinder barrel | TIG & MIG

In this video we are machining and welding a new barrel for a road milling machine (road profiler) hydraulic lift cylinder. The original cylinder barrel is damaged and has scratching the whole length inside so this will be a re-barrel machining and welding job. We start by machining the flanges off the barrel and machining the new cylinder barrel for weld prep. Then we fit and TIG weld the end flange onto the new barrel before MIG welding and then counter boring the weld back to spec. The 2nd flange is fitted and MIG welded with metal cored wire to complete. We are using our TM-26120G lathe, ProArc PT-201 welding positioner, WIA weldmatic 500i welder.
