SCIENTIFIC-TECHNICAL SECTION

Khalimov A. A., Khudyakov D. S., Faizov I. F. � Estimated tolerable parameters of the diffused hard and soft interlayers in heterogeneous welds

It is shown that formation of areas with different strength properties is possible in heterogeneous tubing connections from low-carbon steels ��3, 20, 20K, 22K, 12X2M1, etc. to high-alloy corrosive steels 08X13, 08X16H10T at conducting welding operations and further continuous service. Calculated dependencies of the estimated tolerable geometric and mechanical parameters of the diffused hard and soft interlayers are shown, which ensure necessary working capacity and operation safety of the heterogeneous welds.
Key words: hard and soft interlayers, tubing, working capacity, operation safety
