摘要： A composite article and process for producing the composite article may include the following steps: i) coupling with interference a first component at least partially made of cast iron and a second component at least partially made of steel; ii) arranging one or more wires of filler material at one or more separation zones between said first and second component; iii) in an inert atmosphere, directing a laser beam mostly or exclusively on the steel of the second component and on the filler material for occupying at least part of the separation zone at least with said molten steel and filler material; iv) solidifying by cooling at least the molten steel and filler material in welding zones to join said first and second component, and thus obtaining the article.
