In a ten-year study of filler metal compositions and techniques for welding columbium-stabilized 18-8 stainless steel, seven electrode compositions have been evaluated. The correct choice among these electrodes will depend on the temperature, surroundings, and other conditions of service.nThe study began with a survey of welding fabricators to determine the frequency and types of weld metal cracking experienced by American industry. Once the problem was defined, a program was outlined to develop suitable weld metal compositions to join Type 347 for various types of service.
