Suspectibility to hydrogen induced cracking of weld beads on high-strength structural steelMalina, Jadranka (Avtor) Samardžić, Ivan (Avtor) Gliha, Vladimir (Avtor) weldingwelded jointsmaterialsstructural steelcrackinghydrogenWe study the hydrogen embrittlement and rupture of specimens of high-strength low-alloy steel with weld beads subjected to hydrogenation under the conditions of cathodic polarization. The specimens fail in the heat-affected zone on the boundary between the main metal and the weld bead in the zone of application of the latter and, especially, near its end. This explained by a higher hardness of the metal in this zone caused by the specific features of the temperature field formed in the process of welding.20052012-06-01 09:48:40Neznano27104sl
