Summary: | The invention belongs to the technical field of welding materials, and particularly relates to a high-toughness stainless steel welding rod used in an ultralow-temperature environment and a preparation method thereof.The high-toughness stainless steel welding rod used in the ultralow-temperature environment comprises a welding core and a coating adhering to the outer wall of the welding core; the coating is mainly prepared from, by weight, 25%-30% of rutile, 10%-15% of iron powder, 10%-15% of feldspar, 10%-15% of fluorite, 5%-10% of chromium powder, 5%-10% of nickel powder, 5%-10% of marble, 2%-5% of electrolytic manganese metal, 2%-5% of molybdenum powder, 2%-5% of mica, 2%-5% of titanium dioxide, 1%-4% of cryolite, 1%-4% of ferrotitanium and 1%-2% of sodium carbonate. The invention provides a high-toughness E316L-16 stainless steel welding rod used in an ultralow-temperature environment. The high-toughness E316L-16 stainless steel welding rod has a certain ferrite number and excellent low-temperature impact |
