I need to demagnetize various grades of SS seamless tubing in lengths less than 12". The tubing is first hand selected and tested for low to non-magnetic properties using 1/8oz neodymium magnets. All cutting, filing and finishing are all done by hand to prevent frequency build up from high-speed tools. The only process I cannot avoid is welding, and of all the modalities of welding TIG (GTAW) w/316L SS rod leaves the least residual magnetization and the cleanest weld. The finished SS product ends up slightly magnetized, indicated by the neodymium magnet sticking under its own weight or only momentarily attracted then falling away. This is unacceptable around the sensitive measuring equipment being used.
