ABSTRACT:
A fluid filter, such as an oil filter for example, has a canister, a top plate and a sealing ring. The sealing ring overlaps portions of the top plate and canister. The sealing ring and canister are joined one to the other by laser welding about the sealing ring adjacent the canister and forming a mechanical lock between the canister and the top plate by mixing of materials.
