Randy, I'm not sure if you have a copy of "The Mechanics handbook to jobsite language" but I looked up "Weldering"and
basically its the art of joining two metals with the best machines( most expensive usually) available and all the correct tooling and gadgets without any "Skills".... as opposed to "Welding" which is like what Shawn Carr, Mike Lee , Doc Al and many others who can "join metals" with the cheapest simplest oldest tooling available and make it art like...
I am a proud member of the "Welderers Union"....
I think a similar analogy for you would be "portering"....
