Abstract : This report reviews the current status of the program to explore the effectiveness of various compositions of maraging steel filler metals and joining procedures for achieving tough weldments having a yield strength between 180 and 210 ksi. The status of two development activities are covered: (1) improved MIG filler metals and (2) improved joining techniques. These studies have included the evaluation of 18% Ni-Co-Mo and 12% Ni-Cr-Mo maraging steels. In addition a preliminary literature review of the status of welding maraging steels also is presented. The status of several other promising alloy systems currently under investigation will be reported separately. (Author)
