Wide range of components from very large section sizes to very small, also for bi-metallic materials.
Thompson's friction welding capabilities cover many material combinations and geometry options including bar to bar, tube to bar, bar to plate, tube to plate and tube to tube, for example. Commonly friction welded components include drill rods, axles, drive shafts, pump shafts and cv joints. 
Automotive components: Many components in the automotive industry are friction welded. These components include: Turbo Chargers, Airbag canisters, CV Joints, Shock Absorbers, Engine Valves, Drive Shafts, Gear Shafts, Battery Contacts, Break Disks, Crank Shafts, Torque Converters, Cable Lugs, Pistons, Grounding Cables, Break Cylinders, Camshafts
Bi-metallic and Dissimilar Material Components: The friction welding process is very commonly selected for bonding applications with bi-metallic/dissimilar material combinations. With friction welding, we can bond certain material and alloy combinations that are considered either un-weldable or poor, through conventional welding methods, for example: Copper to Aluminium (Aluminum - USA), Copper to Stainless Steel, Aluminium to Stainless Steel, Mild Steel to Stainless Steel, Titanium to aluminium , And many more
Drill rods and drill pipes: All types of drill pipes and be joined by the rotary friction welding process, a well as percussive rock drills, rotary drills and tunnelling rods. Suitable materials include a range of construction and engineering steels, carbursing, API and nitriding steels.
KUKA RFW Thompson_Electrical distribution
Components for electrical power distribution, pump shafts and plug valves in materials ranging from copper/aluminium and copper/steel to heat resistant stainless steels, nickel alloys and titanium.
Thompson Subcontract manufacturing Heavy automation axles
The world leading Thompson double ended solution has the capacity for welding two fully machined spindles to axles housing or tubes, simultaneously.
KUKA Thompson Sub Contract_Piston rods
Piston rods: Eyes and clevises can be joined to pre-chromed rods as well as caps and flanges to cylinders in a selection of engineering steels, in various combinations such as induction hardened and hard-chromed related conditions.
Small Diameter Components: Common applications include hand tool components and engine valves in a range of ferrous and non-ferrous materials. Common small diameter applications include: Engine Valves, Ball Screw Shafts, Hand tools, Gear Shafts
