Description

Известно электродное покрытие, содержащее мрамор, плавиковый шпат, двуокись титана, ферротитан и алюминий.Known electrode coating containing marble, fluorspar, titanium dioxide, ferrotitanium and aluminum.

Дл повышени производительности сварки к механических свойств металла шва в состав электродного покрыти введен однофазный иорошок в количестве 60-72% следующего состава (в %): хром 50-61,5, никель 32-43,5, кремний 1-3, марганец 4-14. Другие комноненты вз ты в следующем процентном соотношении: мрамор 14,3-20,1, плавиковый игиат 12,2-17,3; двуокись титаиа 1,5-2,6.To improve the performance of welding to the mechanical properties of the weld metal, a single-phase ioroshk was introduced into the composition of the electrode coating in the amount of 60-72% of the following composition (in%): chromium 50-61.5, nickel 32-43.5, silicon 1-3, manganese 4 -14. Other components are taken in the following percentage: marble 14.3-20.1, hydrofluoric limestone 12.2-17.3; titanium dioxide 1.5-2.6.

В состав однофазного порошка может быть дополнительно введены титан до 2%, ниобий до 2,5% или ванадий до , или молибден до 6, и ванадий до 1,5о/а совместно.. В порошок , содержащий хром, иикель, кремний, марганец, может быть также добавлен молибден до I,5Vo или ниобий до 2Vo и вольфрам до 2,5э/о.The composition of the single-phase powder can be additionally introduced titanium up to 2%, niobium up to 2.5% or vanadium up to, or molybdenum up to 6, and vanadium up to 1.5o / a together .. Into powder containing chromium, nickel, silicon, manganese , molybdenum up to I, 5Vo or niobium up to 2Vo and tungsten up to 2.5 e / o can also be added.

Предложенное электродное покрытне, содержащее однофазный порощок сложного состава , нозвол ет получить сварное соединение ири сварке кислотостойких сталей с высокндш механическими свойствами.The proposed electrode coating, containing a single-phase powder of complex composition, can produce a welded joint and weld acid-resistant steels with high mechanical properties.
