WELDING WIRE FOR FE-36NI ALLOY.

摘要

The invention concerns a welding wire intended to be used for welding together portions of parts made from Fe-36Ni alloy. This welding wire is made from an alloy comprising, in % by weight: 38.6% ≤ Ni+Co ≤ 45.0%; traces ≤ Co ≤ 0.50%; 2.25% ≤ Ti+Nb ≤ 0.8667 x (Ni+Co) - 31.20% if 38.6% ≤ Ni+Co ≤ 40.33%; 2.25% ≤ Ti+Nb ≤ 3.75% if 40.33% ≤ Ni+Co ≤ 41.4%; 0.4167 x (Ni+Co) - 15.0% ≤ Ti+Nb ≤ 3.75% if 41.4% ≤ Ni+Co ≤ 45.0%; traces ≤ Nb ≤ 0.50%; 0.01% ≤ Mn ≤ 0.30%; 0.01% ≤ Si ≤ 0.25%; traces ≤ C ≤ 0.05%; traces ≤ Cr ≤ 0.50%, the remainder consisting of iron and inevitable impurities resulting from production.
