ABSTRACT OF THE DISCLOSURE This invention discloses a partially consumable spacer chill or welding ring which includes a generally cylindrical non-consumable base metal ring having an outside diameter of such a size as to snugly fit the inside diameter of the pipe end to be welded. A circular consumable filler metal spacer ring is medially attached to the outer periphery of the base metal ring and extends peripherally radially outwardly to function as a spacing device between adjacent ends of two lengths of pipe to be joined. The consumable spacer ring may be affixed to the base metal ring in a plurality of circularly offset locations by spot welding or may be press-fitted in an alignment groove in the base ring. The consumable spacer ring becomes filler metal during welding.
