I have a trivia question. What to the letters in teh acronym, A R C, mean regarding welding? My dad's a pipeline welder, but I can't reach him to ask. I wonder if it's a trick question..... Regards, Rhonda Cross
ARC isn't an acronym. It refers to the open electric arc in the gap space between the electrode and the workpiece. Arc welding differs from spot welding or projection welding in this respect.
The reason there have not been any more responses is that DoorMan gave the correct answer, and besides the little insertion of humor, no more needs to be said.
