| Abstract: | Metal magnetic memory testing(MMT) is a new nondestructive testing technology.it can test strese distribution state of metal parts,and learn the trend to possible crash of tested parts was decided if continuing use. MMT has been applied to testing of steam power generator unit in operation,such as fillet weld of headers,fillet weld of ceiling,turbine blade etc,and has achieved expectant testing results. |
