de-Gaussing magnetized pipe prior to welding

[kstaylor]

Does anybody have a sure-fire way of de-Gaussing a piece of 9Cr-1Mo pipe in order to make a GTAW weld? The section of pipe is magnetic and plays havoc with the arc from the Tig torch!

Use a single or if more power is required yorks from a magnetic particle tester., Use AC put on and pull off. Several times may be required.
