Description
Automatyczne spawanie austenitycznej stali chromoniklowej w gazie ochronnym jest obec¬ nie stosowane w coraz szerszym zakresie, a to ze wzgledu na gospodaricze korzysci, jakie daje ta metoda. W zwyklych warunkach spawania metoda ta ma jednak -powazna wade, polegaja¬ ca na tym, ze w spoiwie powstaja na goraco znane szczeliny.Obecnie stwierdzono, ze przez odpowiedni dobór spoiwa do spawania mozna zapobiec powstawaniu tych sizczelin, przy czym w zad¬ nym razie nie jest konieczne, aby sklad spoiwa byl taki sam jak sklad spawanego materialu, oczywiscie pod warunkiem, ze material, który ma byc spawany, jest austenityczna stala chro- moniiklowa, dagaca sie spawac.Zgodnie z wynalazkiem stosuje sie spoiwo o skladzie: 0,05 — 0,2% C, 0,70 — 1% Si, 1,5 — 2,5% Mn, 24-26% Cr, 19 - 21% Nd, 0,2 — 1% Ti ifliub Zr, przy czym reszte stanowi zelazo oraz nie dajace sie uniknac zanieczyszczenia.Godnym uwagi jest fakt, ze nie mozna osia¬ gnac zadowalajacych wyników przy stosowaniu spoiwa, zawierajacego molibden, na przyklad spoiwa o zawartosci 25% Cr, 20 — 25% Ni oraz 1-2,5% molibdenu.Przedmiotem wynalazku jesit wieje spoiwo do spawania i napawania w gazie ochronnym austenitycznej, spawalnej stali chromoniklowej, skladajace sie z 0,05 — 0,2% C, 0,7 — 1% Si, 1,5 — 2,5% Mn, 24 — 26% Cr, 19—21% Ni, 0,2— 1% Ti i/lub Zr, przy czym reszte stanowi zela¬ zo i nie dajace sie uniknac zanieczyszczenia.Jako gaz ochronny moga byc stosowane zna¬ ne gazy obojetne, jak równiez dwutlenek wegla sam lub w mieszaninie z gazami obojetnymi, a ewentualnie z dodatkiem tlenu. PLAutomatic welding of austenitic chromium-nickel steel in a protective gas is now used to an increasing extent because of the economic benefits of this method. Under normal welding conditions, however, this method has the serious disadvantage that known hot gaps are formed in the filler metal. It has now been found that by selecting the appropriate filler metal for welding, the formation of these cracks can be prevented, in any case it is not necessary that the composition of the binder is the same as that of the material to be welded, of course on the condition that the material to be welded is an austenitic chromium-nickel steel, which is difficult to weld. - 0.2% C, 0.70 - 1% Si, 1.5 - 2.5% Mn, 24-26% Cr, 19 - 21% Nd, 0.2 - 1% Ti if or Zr, the rest it is iron and unavoidable contamination. It is noteworthy that satisfactory results cannot be achieved with a binder containing molybdenum, for example binders containing 25% Cr, 20-25% Ni and 1-2.5% The subject of the invention is blowing a filler metal for welding and surfacing in a protective gas, austenitic, weldable steel and chromium-nickel, consisting of 0.05-0.2% C, 0.7-1% Si, 1.5-2.5% Mn, 24-26% Cr, 19-21% Ni, 0.2- 1% Ti and / or Zr, the remainder being iron and unavoidable contamination. As protective gas, known inert gases can be used as well as carbon dioxide alone or in a mixture with inert gases, possibly with an additive oxygen. PL
