Abstract
A method of joining metal materials by spraying molten metal into a cavity between the articles to be joined. Prior to deposition of the metal, the surface of the cavity is cleaned and the articles to be joined are preheated. Subsequent to deposition of the metal within the cavity, the joined articles are cooled at a rate that precludes damage due to thermal effects and the deposited metal is consolidated in the cavity by hot pressing.
