WELDED JOINT FORMED BY WELDED SEAM METAL BASED ON STAINLESS STEEL INTENDED FOR WELDING STEEL SHEET WITH ZINC-BASED COAT Russian patent published in 2011 - IPC B23K33/00 B23K101/18 F16S5/00 C22C38/00 

FIELD: metallurgy.

SUBSTANCE: welded joint comprises steel sheets 1 and 4 with zinc-based coat, and welded seam 5, 6 jointing said sheets together. Said welded seam comprises the following components in wt %: C - 0.01-0.1; Si - 0.1-1; Mn - 0.5-2.5; Ni - 5-11; Cr - 17-25, if required, Mo - 0.5-2, and N - 0.05-0.15, and, if required, one or several elements selected from Nb, V, Ti and Al in amount of up to 0.1 %, iron and admixtures making the rest. The following relationships are observed: -0.81 Cr_eqv+ 23.2 ≤ Ni_eqv ≤ 0.95×Cr_eqv - 8.1; Ni_eqv = Ni + 30×C + 0,5×Mn + 30×N; Cr_eqv = Cr + Mo + 1.5×Si.

EFFECT: high antirust properties and cracking resistance in embrittlement by liquid metal.
