WELDING OF EI 712 STEEL (12KH2NVFA)
Abstract
Weldability tests were carried out on specimens and structures made of EI712 steel with a thickness of 1.5; 1.8; 2 and 3 mm in annealed, normalized and hardened states prior and after the welding. Test plates were automatically welded in a carbon dioxide and an argon medium using an electrode wire 18KHMA, manual argon-arc welding with an Sv-08A wire and manual arc welding with a metal electrode type UONI-13/55 with a rod made of Sv-08A wire. The results showed that welded units of EI712 steel, regardless of the welding method and thermal processing of details prior to or after the welding had high strength and plasticity. (Author)
