The application of magnetic methods at the quality control of welded designs made from increased durability steel
The results of determination of the residual tensions in welded elements from the low-alloyed increased durability steel classes X65 and Х75, received by a method of holes and means of the final element analysis in the ANSYS software are given in this work. The assessment of influence of thermal processing on the level of the residual tensions in welded elements is made. The comparison of values of the tension received by a method of holes and sizes of intensity of the magnetic field of demagnetized has established correlation dependencies for an assessment of tensely deformed condition of welded elements from investigated steel in the initial and thermally processed condition.
