Development of Low Cost Filler Materials for Welding High Strength Steels.
Abstract
In the GMAW system, equipment was built to feed a second wire into the leading edge of the pool. Commercial welding wires were selected and used to produce the required composition with good homogeneity in the weld metal. In the SMAW system two approaches were investigated to produce weld metal of target composition by alloying two wires rather than by relying on alloying elements contained in the coating of the rod (as per commercial practice). Electrodes made from a tube with an alloy wire inside and others made from a solid rod with a ribbon of alloy material tacked to the outside both showed excellent welding characteristics with homogenous weld metal compositions.
