Abstract
A method for joining a first metal part with a second metal part, the metal parts having a solidus temperature above 1000° C. The method includes applying a melting depressant composition on a surface of the first metal part, the melting depressant composition including a melting depressant component that includes phosphorus and silicon for decreasing a melting temperature of the first metal part; bringing the second metal part into contact with the melting depressant composition at a contact point on said surface; heating the first and second metal parts to a temperature above 1000° C.; and allowing a melted metal layer of the first metal component to solidify, such that a joint is obtained at the contact point. The melting depressant composition and related products are also described.
