Abstract
A support fitting for the heat-resistant block to protect boiler tubes, which protrudes upward at a right angle from the surface of the rib between two boiler tubes, and which is welded on the rib and has a catch to engage with the heat-resistant block on the end. The support fitting is provided with a welding surface to be welded on the rib and shaped narrower by chamfering, and a single globule of a deoxidizing conductive material used as flux is attached to the narrowed welding surface, and is a vertical piece or rod which extends a fixed distance perpendicular from the rib. The support fitting includes a first upper surface being kept horizontal to support a ferrule, which can tightly engage with the ferrule for arc stud welding, thereby the ferrule can shield the welding surface, and a second upper surface which engages with the heat-resistant block.
