An investigation was conducted on the repair welding of high strength yellow brass castings. Test castings oxyacetylene gas and inert-gas-shielded-arc welded with several types of fillers were evaluated. Tensile and bend tests on samples removed from these castings showed that satisfactory high strength, high ductility welds could be obtained by inert-gas-shielded-arc welding with base metal composition filler and high manganese aluminum bronze alloy filler. Several production castings welded in this manner supported the experimental results. Additional information is presented on microhardness tests and metallographic interpretation of the weld deposits.
