摘要：
The development of cold cracks of delayed fracture in rigid process samples and small-size pieces from low-alloy high-strength steel 14Kh2GMR is studied with the use of simulation of the welding process. The experimental data are used to suggest a mechanism of the action of hydrogen on plastic strain in the range of pre-fracture of welded joints.
