Electron beam technologies touch our lives in ways that few people realize. electron beam lithography is used to manufacture the semiconductor devices we use every day. electron microscopes produce the high magnification images that have advanced science.. Friction stir welding (fsw) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material. heat is generated by friction between the rotating tool and the workpiece material, which leads to a softened region near the fsw tool.. In the mandrel mill process, a solid round (billet) is used. it is heated in a rotary hearth heating furnace and then pierced by a piercer. the pierced billet or hollow shell is rolled by a mandrel mill to reduce the outside diameter and wall thickness which forms a multiple length mother tube..
