How to Weld on a Sprocket

A sprocket is a wheel equipped with teeth that works like a gear. It is attached to a rotating bar or rod and is often hooked to a chain or track to create movement in a machine. Weld-on sprockets are attached to the machine via welding, which is the process of joining two pieces of metal together with heat. Welding a sprocket results in a strong, permanent bond.

Instructions

- 1
  Slide the sprocket onto the rod. Align the sprocket with the chain or track.
- 2
  Equip an arc welder with AC current with a welding rod. Use a 6010, 6011, 6013, 7018 or 7024 welding rod, all of which are used for general welding projects.
- 3
  Set the arc welder to the recommended power for the welding rod, which is found on the packaging.
- 4
  Put on a pair of welding gloves and a welding mask. Lower the shield on the welding mask, so it covers your face.
- 5
  Hold the tip of the welding rod above where the inner ring of the sprocket meets the rod. The gap must be welded to bond the sprocket and rod together. Hold the arc welder so the welding rod is positioned in a 30 to 45 degree angle tilting away from the sprocket.
- 6
  Touch the tip of the welding rod to the gap to weld the sprocket and rod together. Move the welding rod around the entire perimeter of the sprocket until there is no gap remaining. Keep the welding rod tilted while welding.
