Mubikorwa byo gukora umunara wamashanyarazi, gusudira ninzira yingenzi.Ubwiza bwo gusudira bugira ingaruka ku buryo butaziguye umusaruro w’umunara.Niyo mpamvu, birakenewe kumva impamvu zitera inenge hamwe ningamba zitandukanye zo gukumira.
1. Umwobo wo mu kirere hamwe no gushyiramo slag
Ububabare: Ububabare bivuga umwobo wakozwe mugihe gaze muri pisine yashongeshejwe idacika mbere yo gukomera kwicyuma kandi ikaguma muri weld.Gazi yayo irashobora kwinjizwa na pisine yashongeshejwe hanze, cyangwa irashobora kubyara reaction mugikorwa cyo gusudira metallurgie.
. , irangi ryamavuta, hamwe nubushuhe bwo gutwikira no gutembera kwinkoni yo gusudira ibora gaze mubushyuhe bwinshi, byongera ibirimo gaze mubyuma byo hejuru.Ingufu zo gusudira ingufu ni nto cyane, kandi umuvuduko wo gukonjesha wa pisine yashongeshejwe ni nini, ntabwo bifasha guhunga gaze.Deoxidisation idahagije yicyuma gisudira nayo izongera umwuka wa ogisijeni.
.Ububabare nabwo butera guhangayika.Hydrogen porosity nayo ishobora kugira uruhare mukumena ubukonje.
Ingamba zo gukumira:
a.Kuraho amavuta, ingese, amazi na sundries mumigozi yo gusudira, igikoni gikora hamwe nubuso bwacyo.
b.Inkoni yo gusudira ya alkaline na flux bigomba gukoreshwa kandi byumye neza.
c.DC ihuza ihuza hamwe na arc gusudira bigufi bizemerwa.
D. Shyushya mbere yo gusudira kugirango ugabanye umuvuduko ukonje.
E. Gusudira bigomba gukorwa hamwe nibisobanuro bikomeye.
Crackle
Ingamba zo gukumira ibice bya kirisiti:
a.Mugabanye ibiri mubintu byangiza nka sulfure na fosifore, hanyuma usudire hamwe nibikoresho birimo karubone nkeya.
b.Ibintu bimwe na bimwe bivanze byongeweho kugabanya inkingi za kristu no gutandukanya.Kurugero, aluminium nicyuma birashobora gutunganya ibinyampeke.
c.Gusudira hamwe no gucengera cyane bizakoreshwa mugutezimbere ubushyuhe kugirango ibintu bigabanuke hejuru yibikoresho byo hejuru kandi ntibibaho muri weld.
d.Ibisobanuro byo gusudira bizatoranywa mu buryo bushyize mu gaciro, kandi bizashyirwa mu bikorwa mbere yo gushyushya no kugabanya ubushyuhe.
e.Emera uburyo bukwiye bwo guterana kugirango ugabanye gusudira.
Ingamba zo gukumira ubushyuhe buke:
a.Witondere ingaruka zishimangira ibintu bya metallurgjique ningaruka zabyo kumashanyarazi.
b.Bishyushye ushushe cyangwa ukoreshe nyuma yubushyuhe kugirango ugabanye igipimo cyo gukonja.
c.Mugabanye imihangayiko isigaye kugirango wirinde guhangayika.
d.Mugihe cy'ubushyuhe, irinde ahantu h'ubushyuhe bukabije bwo gushyuha cyangwa kugabanya igihe cyo gutura muri ubu bushyuhe.
Ingamba zo gukumira ibicurane bikonje:
a.Ubwoko bwa hydrogène yo mu bwoko bwa alkaline yo gusudira bugomba gukoreshwa, gukama neza, kubikwa kuri 100-150 and, no gukoreshwa mugihe ufata.
b.Ubushyuhe bwo gushyuha bugomba kwiyongera, hazafatwa ingamba zo gushyushya post, kandi ubushyuhe bwa interpass ntibushobora kuba munsi yubushyuhe bwo gushyuha.Ibisobanuro byo gusudira byumvikana bizatoranywa kugirango birinde gusenyuka no gukomera muri weld.
c.Hitamo uburyo bukwiye bwo gusudira kugirango ugabanye gusudira no gusudira.
d.Kora hydrogène yo gukuraho ubushyuhe mugihe cyo gusudira
