Then why didn't EMD then use wirefeed welding / mig? This process does not 
produce the "slag" that "stick welding" does. Although the weld penetration 
would be about 1/2 to what stick welding would be. 


If it was only one welder that welded improperly, and it certainly 
could have been, I am surprised that Engineering and Service didn't 
figure that out more quickly. There was a great amount of 
investigative work done once the first several failures occurred 
about 1968 and the design was changed in the very early '70s. In 
general, the welders that were assigned to critical crankcase welding 
were the more senior and skilled. As an interesting sidelight, in 
that period, EMD was the largest user of welding rod in the entire 
state of Illinois!
