A method of joining tubulars includes the step of joining the tubulars by forge welding. The tubular ends that are to be welded together may be shaped into a sloping configuration, such that when the tubular ends are heated during the forge welding process the heated tubular ends deform as a result of thermal expansion into a substantially longitudinally oriented cylindrical shape.
