Abstract:V predstavljenem delu smo študirali občutljivost treh jekel za pokljivost v hladnem pri uporabi implant-preizkusov. Ta vrsta pokljivosti se pojavi v varu ali v toplotno vplivanem področju v odvisnosti od tega, kateri del zvara je bolj kaljiv. Odločilni dejavniki za pojav pokljivosti v hladnem so vodik, kaljene strukture in zaostale napetosti. Trajna implantna trdnost je prag napetosti, pri kateri pri danih pogojih ne pride do pokljivosti v hladnem v grobozrnatem delu toplotno vplivanega področja preizkušanega jekla. To smo določili pri jeklih CrNiMoV, CrMoV in SUMITEN 80 P pri različnih pogojih. Pri tej raziskavi je zmanjšanje vlage v dodajnem materialu in predgrevanje močno povečalo implantno trdnost.

Title:The implant strength of three structural carbon steels
Abstract:In the presented research work the sensitivity of three steels on cold cracking were studied using an implant test. Cold cracking appearsin the weld metalsor in the heat-affected zones, depending on which part of the weld joint ismore hardenable. The crucial factors for cold cracking are hydrogen, the hardened microstructure and the residual stresses. The implant strength is defined as the threshold stress for the appearance at no cold cracks in the coarse-grain heat-affected zone under certain condition. The implant strengths were determined on CrNiMoV steel, CrMoV steel, and SUMITEN 80 P steel under different conditions. In the presented research the lowering of the humidity in the consumable and preheating drastically increase the implant strength.
Keywords:structural steels, welded joints, implant test, implantna strength, cold cracking, HAZ, weld metal
