Structure and Properties of Laser-Welded Joints from High-Strength Steels
Presented are the results of investigations of peculiarities of structure formation and phase composition in a metal of laser-welded joints from high-strength steel 14KhGN2MDAFB. The analytical evaluations of strengthening along a welding zone and crack nucleation stresses in the places of stress concentrators determined using the experimental data that a structure being formed provides for uniform level of mechanical properties and crack resistance of the welded joints.
