Only if you can clamp it somehow. I'd guess, no.
One thing with using a welder, on iron pipe it works great, but copper pipe has little resistance and will tend to overheat the welder real fast, or trip circuit breakers. If you're going to try it, turn it on for 30 seconds, then off for 2 minutes, then again.
They make a pipe thawing machine that's made for the purpose, they are similar to a welder, but cost more. I think they have more windings, but maybe part of the cost is the directions they come with. When thawing copper pipe you have to calculate the length and size and then use a watch with a second hand. You run it for a certain time and then wait. After some minutes you can do it again. They warn that you can melt the solder out of the fittings if not used per directions. Iron pipe you can just hook on & wait til water flows.
