초록
Thermomechanically cold processed (TMCP) steels with a high level of strength are actively used in various constructions. The high strength of the TMCP steels is acquired due to the formation of the fine-grained structure. Such steels have relativelylow carbon percentage. These greatly simplify the solution of the problem of improving the quality and reliability of metalstructures. At the same time this raises new questions in terms of the technology for welding such steels. In the first instance,it is conditioned by the complex behavior of the TMCP structure under the welding thermal cycle effect. The most importantproperty of the welded joint is yield stress (YS) which characterizes the workability of the whole joint. The estimation ofthe YS while developing the welding technology is a valuable task for design. This current research has made a complexinvestigation of the modern welding technique's effect on the behavior of the yield stress formation in TMCP steel weldedjoints. For progressive technology development, pulse arc welding was used.
