| Abstract: | Several testing methods for broken mandrel in cold-rolled steel pipes are studied. For the magnetic testing method ,the distribution of testing signal sources as well as the advantages and disadvantages in the measurement with magnetic sensitive elements is discussed. Results show that the magnetic testing method is the best. |
