Abstract
Inventia se refera la un electrod bazic pentru sudarea cu arc electric, destinat sudarii otelului care lucreaza în medii corosive. Electrodul, conform inventiei, este alcatuit dintr-o vergea de otel care are în compozitie 0,4...0,6% Mn si un înveliscontinând pulbere de marmura, rutil, feromangan si ferosiliciu, pulbere de fier. Vergeaua de otel contine, în procente de greutate, 0,08% C, 0,4...0,6% Mn, 0,25% Si, 0,015% P, 0,01% S, 0,20% Cu, 0,06% As, iar învelisul este alcatuit, în procente de greutate, din : 4...10% rutil, 20...35% marmura, 15...25% fluorina, 3,5...6 feromangan, 4,5...7 ferosiliciu, 20...35 pulbere de fier, 3...8 silicat de sodiu, 0,5...3% feldspat, 0,5...2,5% carboximetilceluloza, 0,5...2,5% celuloza.
