A method is provided for welding together a tubular member of a first metal and a tubular member of a second metal that is dissimilar to the first metal. The method includes making a transition attachment by friction welding together end-to-end a first end of a rod of the first metal with a first end of a rod of the second metal. An arc weld welds together a second end of the rod of the first metal with the tubular member of the first metal. And another arc weld welds together a second end of the rod of the second metal to the tubular member of the second metal.
