ASYMMETRIC HEAT SINK WELDING USING A PENETRATION ENHANCING COMPOUND

摘要

A method for welding a tube member to a tubesheet includes positioning an open end of a tube member adjacent to a first side of the tubesheet and with the tube member extending through the tubesheet past a second side of the tubesheet. A penetration enhancing compound is applied to an inner side of the tube member at a location adjacent to a junction between an outer side of the tube member and the tubesheet second side. An arc welding operation is performed at the location of the penetration enhancing compound to effect formation of a weld joint at the junction between the tube member outer side and the tubesheet second side.
