One of the questions in some of the litigation involved improper choice
of welding consumables. Lincoln Electric was blamed for supplying weld
electrodes that produced non-ductile welds as evidenced by low Charpy
results. I think the question was whether Lincoln exerted undue pressure
to buy the electrodes, which coincidently had a high deposition rate and
were seen as a way to save money. My own feeling is that any engineer who
specifies a weld electrode on the basis of deposition rate doesn't know
enough about welding to be in the electrode-specification business, which
is definitely an engineering function.
There was an article somewhere on this in one of the LA papers a year or
