Zusammenfassung:	A method of interconnecting a pair of metal oilfield tubulars having complementary tapered edges with a common contact surface when the tubulars are interconnected, is provided. The method consist of having a melting temperature lower than the melting temperature of the tubulars, interconnecting the tubulars whereby the think layer of metal is in between the tubulars, applying heat to the thin layer of metal so as to melt the thin layer of metal, and cooling the tapered edges whereby a metallurgical bond is created between the tubulars.
