Inkoni yo gusudira ya E312 Yujuje ibisabwa na AWS E312-17 kandi ni yo gisubizo gikunzwe cyane mu gusudira intoki mu buryo butandukanye kandi bufite ireme ryo hejuru (SMAW). Yagenewe gusudira ahantu hose, electrode irakora neza mu gukora no gusana ibintu bigoye hamwe n'icyerekezo gihinduka cyo gusudira. Akamaro kayo k'ingenzi ni ubushobozi bwayo bwo gukora ahantu hakomeye kandi hadacikagurika ku bikoresho bitandukanye by'ibanze bigoye, harimo ibyuma bitandukanye bitarangirika, ibyuma bitandukanye bivanze n'ibyuma bifite ibara ryinshi, cyane cyane mu bihe aho kudashyuha kw'ubushyuhe ari ingenzi.
Electrode za E312 zikoresha electrode ya austenitic irangwa n'ingano nyinshi ya chromium n'ingano nyinshi ya nikeli. Iyi miterere yihariye iha ubushobozi bwo kurwanya ubushyuhe bukabije, ikaba ari ikibazo gikunze kugaragara mu gihe cyo gusudira ingingo zigoye cyane, ibyuma bitandukanye, cyangwa ibyuma bishwanyagurika byoroshye. Ibyuma bivamo ubushyuhe bigaragaza imbaraga nziza zo gukurura haba mu bushyuhe bwo mu cyumba no mu bushyuhe buri hejuru, kandi bifite ubushobozi bwo kugenda neza no gukomera.
E312-17 ni umwihariko mu miterere yayo myiza yo kuyikoresha.Inkoni yo gusudira ya E312 (AWS E312-17) isa na electrode ya E312-16, ariko uburyo bwo gusiga irangi bwayo bwongereye ingano ya silikoni kandi igabanya ingano ya titaniyumu. Uku gutunganya witonze kunoza cyane uburyo arc ihagaze mu myanya yose, cyane cyane mu buryo bugoye bwo gusudira hejuru y'ifishi no gusudira hejuru mu buryo bugororotse. Ubu buryo butanga ingaruka zidasanzwe za "jet arc" iyo zikoreshejwe mu gusudira mu buryo butambitse.
Electrode ya E312 ifite uburyo bwinshi cyane bwo kuyikoresha. Ni yo ikoreshwa cyane mu guhuza ibyuma bitandukanye, ibyuma bita "austenitic stainless steels" na karubone cyangwa "low alloy", n'ibyuma byinshi bya nikeli ku byuma. Ikora neza cyane mu gukoresha "overallowing" no "cladding" aho bisaba kwangirika no kudakora neza. Iyi electrode kandi ifatwa nk'iy'ingenzi mu gusana "castiling" zishobora kwangirika. Inganda z'ingenzi zishingiye ku mikorere yayo zirimo amashanyarazi, gutunganya imiti na peteroli, "pulp" n'impapuro, ndetse no gukora no kubungabunga ibikoresho biremereye.
Inkoni yo gusudira ya E312 (AWS E312-17) itanga ubushobozi bwo gukora ibintu bitandukanye kandi byizewe mu mirimo ikomeye yo gusudira isaba gusudira ahantu hose, kurwanya imivuniko no gushyiramo imbaraga nyinshi. Ubuhanga bwayo bwihariye bwo gusiga buyiha ingaruka nziza za "jet arc", ituma isudira neza cyane, bigaha umusudi uburyo bwiza bwo kugenzura no gushyiramo ibintu. Ibyuma bivamo austenitic weld bifite ubushobozi bwo kurwanya imivuniko ishyushye no gushonga, bigatuma iba electrode y'ingenzi mu guhuza ibintu nk'ibyuma bitandukanye, ibyuma bifite alloy nyinshi, n'imirimo ikomeye yo gusana.
