Abstract
An improved press fit joint is particularly useful for iron parts. An outer part receives an inner part which is press fit into a bore in the outer part. The outer part has a hole, and the inner part has a dimple which is aligned with the hole when the inner part is forced into the outer part. The dimple has a dimension which is greater than the dimension of the hole. A puddle weld is formed within the hole and in the dimple. The puddle weld thus provides a secondary retention holding the inner part within the outer part.
