Background of stressed state magnetic inspection of steel parts

An operation of IN-01m and IN-02 the metal stress indicators is based on the dependence of magnetic parameter of steel object to be inspected the residual magnetization of metal on the mechanical stress ...

On the calibrating metal stress indicators

Residual magnetic field strength of metal measured by the mechanical stress indicators IN-01m and IN-02 on steel parts produced from different grades of steels might be significantly different...

A technique to determine a reason of high-stressed areas of metal appearance

Providing the metal structure analysis for steel parts is often require to determine a reason of high-stressed condition of the metal observed. Preparing to the metal stress relaxation is also requires to determine its reason...

Automated recognizing and classifying the metal defects using the wavelets

Stress-corrosion cracks, known as most dangerous kind of defects of the metal, are main reason of accidents occurring on the steel pipelines. Generally the stress-corrosion might be viewed as the group of defects of two basic types which are randomly arranged on the surface of metal: convenient cracks and pitting corrosion...
