Ibyuma byinshi bya karubone bivuga ibyuma bya karubone bifite w (C) hejuru ya 0,6%.Ifite imyumvire ikomeye yo gukomera kuruta ibyuma bya karubone yo hagati kandi ikora karubone nyinshi ya martensite, ikaba yunvikana no gushiraho imbeho ikonje.Muri icyo gihe, imiterere ya martensite ikorerwa muri welding yibasiwe nubushyuhe irakomeye kandi iravunika, bigatuma plastike nubukomere bwurugingo bigabanuka cyane.Kubwibyo, gusudira kwicyuma kinini cya karubone birakennye cyane, kandi hagomba gukoreshwa uburyo bwihariye bwo gusudira kugirango imikorere yibihuriweho..Kubwibyo, mubisanzwe ntibikunze gukoreshwa muburyo bwo gusudira.Ibyuma byinshi bya karubone bikoreshwa cyane cyane mubice byimashini zisaba ubukana bwinshi no kwambara birwanya, nk'ibiti bizunguruka, ibikoresho binini hamwe no gufatanya [1].Kugirango uzigame ibyuma no koroshya tekinoroji yo gutunganya, ibi bice byimashini bikunze guhuzwa nuburyo bwo gusudira.Mu gukora imashini ziremereye, ibibazo byo gusudira byibyuma byinshi bya karubone nabyo birahura.Mugihe hategurwa uburyo bwo gusudira ibyuma byo hejuru bya karubone, inenge zitandukanye zishoboka zo gusudira zigomba gusesengurwa byimazeyo kandi hagomba gufatwa ingamba zijyanye no gusudira.
Ibikoresho byo gusudira Xinfa bifite ibiranga ubuziranenge kandi buke.Ushaka ibisobanuro birambuye, nyamuneka sura: Inganda zo gusudira no gutema - Ubushinwa bwo gusudira no gutema uruganda & abatanga ibicuruzwa (xinfatools.com)
1 Weldability yicyuma kinini
1.1 Uburyo bwo gusudira
Icyuma kinini cya karubone gikoreshwa cyane cyane mubikorwa bifite ubukana bwinshi kandi birwanya kwambara cyane, kuburyo rero uburyo nyamukuru bwo gusudira ari electrode arc gusudira, gusya no gusudira arc gusudira.
1.2 Ibikoresho byo gusudira
Gusudira ibyuma byinshi bya karubone muri rusange ntibisaba imbaraga zingana hagati yingingo nicyuma fatizo.Iyo gusudira arc, electrode nkeya ya hydrogène ifite ubushobozi bukomeye bwo kuvanaho sulfure, hydrogène nkeya ikwirakwizwa mubyuma byabitswe, hamwe nubukomezi bwiza bikoreshwa muri rusange.Iyo imbaraga zicyuma gisudira nicyuma fatizo bisabwa kugirango bingane, inkoni yo gusudira ya hydrogène yo mu rwego rwo hejuru igomba guhitamo;mugihe imbaraga zicyuma gisudira nicyuma fatizo bidasabwa, inkoni yo gusudira-hydrogène yo hasi yo gusudira ifite urwego ruri munsi yicyuma cyibanze igomba guhitamo.Ibuka gusudira inkoni hamwe nimbaraga zisumba urwego rwibanze ntirushobora gutoranywa.Niba icyuma fatizo kitemerewe gushyuha mugihe cyo gusudira, kugirango hirindwe ubukonje bwakonje muri zone yibasiwe nubushyuhe, electrode ya austenitike idafite ibyuma irashobora gukoreshwa kugirango ibone imiterere ya austenitike ifite plastike nziza kandi irwanya gukomera.
1.3 Gutegura neza
Kugirango ugabanye igice kinini cya karubone mu cyuma gisudira, igipimo cyo guhuza kigomba kugabanuka, bityo rero U-shusho ya U cyangwa V-V ikoreshwa muri rusange mugihe cyo gusudira, kandi hagomba kwitonderwa gusukura igikoni hamwe n’amavuta, ingese, nibindi muri 20mm kumpande zombi.
1.4
Iyo gusudira hamwe na electrode yubatswe, igomba gushyuha mbere yo gusudira, kandi ubushyuhe bwo gushyuha bugenzurwa hagati ya 250 ° C na 350 ° C.
1.5 Gutunganya interineti
Iyo gusudira ibice byinshi hamwe ninzira nyinshi, electrode ntoya ya diameter hamwe numuyoboro muke bikoreshwa kumurongo wambere.Mubisanzwe, igihangano gishyirwa mugice cya vertike yo gusudira cyangwa inkoni yo gusudira ikoreshwa mukuzunguruka kuruhande, kuburyo akarere kose gaterwa nicyuma gashyuha gashyuha mugihe gito kugirango kibone ingaruka zo gushyushya no kubika ubushyuhe.
1.6 Kuvura ubushyuhe nyuma yo gusudira
Ako kanya nyuma yo gusudira, igihangano gishyirwa mu itanura rishyushya kandi kigashyirwa kuri 650 ° C kugirango bigabanye imihangayiko [3].
2 Gusudira inenge yicyuma kinini cya karubone ningamba zo gukumira
Kuberako ibyuma byinshi bya karubone bifite imbaraga zikomeye zo gukomera, ibice bishyushye hamwe nubukonje bukunze kugaragara mugihe cyo gusudira.
2.1 Ingamba zo gukumira kumashanyarazi
)
)
3) Kubisudira bikomeye, ibipimo bikwiye byo gusudira, urutonde rukwiye rwo gusudira hamwe nicyerekezo bigomba guhitamo.
4) Nibiba ngombwa, fata ingamba zo gushyushya no gutinda buhoro kugirango wirinde ko habaho ubushyuhe bwumuriro.
5) Ongera ubunyobwa bwinkoni yo gusudira cyangwa flux kugirango ugabanye ibintu byanduye muri weld no kunoza urwego rwo gutandukanya.
2.2 Ingamba zo gukumira indwara zikonje [4]
1) Gushyushya mbere yo gusudira no gukonjesha buhoro nyuma yo gusudira ntibishobora kugabanya gusa ubukana nubukonje bwa zone yibasiwe nubushyuhe, ariko kandi byihutisha ikwirakwizwa rya hydrogène hanze muri weld.
2) Hitamo ingamba zikwiye zo gusudira.
3) Emera inteko ikwiye hamwe no gusudira kugirango ugabanye imihangayiko yo kwifata hamwe no kunoza imihangayiko yo gusudira.
4) Hitamo ibikoresho byo gusudira bikwiye, wumishe electrode na flux mbere yo gusudira, hanyuma ubigumane biteguye gukoreshwa.
5) Mbere yo gusudira, amazi, ingese nibindi byanduza hejuru yicyuma cyibanze gikikije igikoni bigomba kuvanwaho neza kugirango bigabanye ibirimo hydrogène ikwirakwizwa muri weld.
6) Kuvura Dehydrogenation bigomba gukorwa ako kanya mbere yo gusudira kugirango hydrogène ihunge burundu hamwe.
7) Kuvura annealing kugabanya ububabare bigomba gukorwa ako kanya nyuma yo gusudira kugirango habeho gukwirakwiza hydrogène hanze muri weld.
3 Umwanzuro
Bitewe nibirimo byinshi bya karubone, gukomera cyane hamwe no kudasuduka kwicyuma kinini cya karubone, biroroshye kubyara karubone ya martensite nini hamwe no gusudira mugihe cyo gusudira.Kubwibyo, mugihe cyo gusudira ibyuma birebire bya karubone, inzira yo gusudira igomba guhitamo neza.Kandi ufate ingamba zijyanye nigihe gikwiye kugirango ugabanye ibibaho byo gusudira no kunoza imikorere yingingo zisudutse.
