WIRE FROM STAINLESS STEEL WITH FLUX CORE FOR WELDING ZINC-COATED STEEL SHEETS Russian patent published in 2011 - IPC B23K35/368 

FIELD: process engineering.

SUBSTANCE: invention may be used in automotive and construction industries. Wire outer metal shell is made from stainless steel. Flux core comprises the following components in wt %, i.e. C - 0.01-0.05, Si - 0.1-1.5, Mn - 0.5-3.0, Ni - 7.0-10.0, Cr - 26.0-30.0. Magnitude F defined as the function of content of said components varies from 30 to 50. Flux contains also slag-forming agent comprising the following components in wt %, i.e. TiO₂ - 0.6-2.6, SiO₂ - 1.8-3.8, ZrO₂ - 1.0-3.5 and Al₂O₃ - 0.1-1.0. Total content of slag-forming agent makes 10% and less. Besides, wire contains Fe and residual admixtures.

EFFECT: ruling out crack formation, higher plasticity and antirust properties of welded seam.
