Abstract
A water valve, guide tube for a water valve, and associated method are provided. The water valve includes a housing and the guide tube is installed on the housing via laser welding. The guide tube and housing each provide axially facing mating surfaces which abut one another in a pre-bonded configuration. In a post-bonded configuration, a laser weld joint is formed at the interface between the mating surfaces. The joint forms a portion of an outer periphery of the housing.
