Why doesn't the work piece melt when arc welding if a lot of amperes run through our electrode?
In arc welding, the local spot where the arc intersects the workpiece is small, so the heat addition is very concentrated right at that spot. This makes it get much hotter than the surrounding metal. … That hotness of course drives heat conduction out of the arc spot and into the cooler surroundings, but the whole point of welding is to overwhelm the conduction process with heat addition that is very …
