Abstract
A method for attaching parts together includes several steps. A metal-core consumable welding wire is obtained in one step. In another step, the parts (such as a ring and a base cup of a cylinder of a damper, such as a vehicle shock absorber) are positioned to create a joint line for welding the parts together. An additional step includes gas metal arc welding the positioned parts together using the metal core wire at a negative electrical welding potential relative to the parts creating a weldment along the joint line. In one example, during welding, the parts have a positive electrical welding potential, and the wire is electrically grounded.
Claims10
A method for attaching a ring to a base cup of a cylinder of a damper comprising the steps of:
- a) obtaining a metal-core consumable welding wire;
- b) disposing the ring in contact with the base cup to create a joint line for welding the ring and the base cup together;
- and
- c) gas metal arc welding the disposed ring and base cup together using the metal-core consumable welding wire at a negative electrical welding potential relative to the ring and base cup creating a weldment along the joint line.
