Abstract:V članku je predstavljena analitična (z empiričnimi enačbami) in eksperimentalna (z Y-preizkusom) določitev temperature predgrevanja visokotrdnostnega jekla Niomol 490 K debeline 19 mm, pri kateri ne bo prišlo do pojava razpok v hladnem v zvarnem spoju. Ugotovljeno je, da je pri varjenju jekla Niomol 490 K z oplaščeno elektrodo EVB NiMo nastanku razpok v hladnem bolj podvržen var kot osnovni material. Z izračuni lahko dovolj natančno napovemo temperaturo predgrevanja jekla, vendar je treba dokazati temperaturo predgrevanja tudi z Y-preizkusom.

Title:An estimation of the cold cracking sensitivity in welds of HSLA steel Niomol 490K
Abstract:This paper deals with the analytical (with empirical equations), and experimental (with JIS-y test) determination of the preheating temperature for HSLA steel Niomol 490K with a thickness of 19 mm, at which cold cracking in the welded joint could be eliminated. It was found that cold cracking is more pronounced in the weld metal than in the base material in steel Niomol 490K welded joints made with covered electrode EVB NiMo. It is possible to predict the preheating temperature using an analytical calculation, but it should be determined by a JIS-y test.
Keywords:HSLA steel, cold cracking, JIS-y test, preheating temperature
