Inzira yo gusudira ifunganye ni iyimbitse kandi ifunganye yo gusudira yo gutunganya ibintu byinshi. Mubisanzwe, ubujyakuzimu-ubugari bwikigereranyo gishobora kugera 10-15. Iyo uburyo bwo gusudira arc bwarohamye bwakoreshejwe, harikibazo cyo gukuraho ibishishwa no gukuraho igikonoshwa cya buri cyuma. Muri rusange uburyo bwo gusudira arc gusudira, twizere ko igikonoshwa gishobora kugwa mu buryo bwikora. Niba igikonoshwa kidashobora kugwa mu buryo bwikora, bizagorana cyane gukuramo intoki igikonoshwa kugirango kibe cyimbitse kandi kigufi gifite ubugari bwa mm 20-30 gusa. Kubera iyo mpamvu, uhereye kumyitozo yuburyo bwo gusudira arc bwarohamye, abantu bakoze ubushakashatsi ku cyuho gito cyarengewe nuburyo bwo gusudira arc uburyo bwo gusudira igishishwa gishobora kugwa mu buryo bwikora - “igipimo cy’amafi” cyasibanganye icyuho gito cyarengewe no gusudira arc.
Itandukaniro riri hagati y '“igipimo cy’amafi” n’isudira rya “conave” (Isanamu 2-36) ni uko igikonoshwa cya shitingi gifite impagarara zitandukanye bitewe n’imfuruka zitandukanye zo gukata hagati y’igikonoshwa n’urukuta rw’uruhande rwakazi (Ishusho 2 -37). Ubusumbane bwubuso bw '“igipimo cy’amafi” gusudira burashobora gutuma igishishwa kigwa mu buryo bwikora; mugihe ubuso bwubuso bwa "conave" weld butuma igikonoshwa gikomera cyane kurukuta rwuruhande rwakazi. Ukurikije impamvu zavuzwe haruguru, icyuho kigufi cyarengewe nogusudira arc ntigomba gukoresha gusudira "conve", ahubwo igomba gukoresha "igipimo cyamafi".
Kuzenguruka arc gusudira birashobora kwinjira mubikorwa hamwe nubunini buri munsi ya mm 20 mugihe kimwe. Bitewe na pisine nini yashongeshejwe, kugirango ugere ku ntego yo gushinga inzira imwe, hagomba gukoreshwa umurongo woguhata kugirango wuzuze icyuzi gishongeshejwe gukonja no gukomera kumurongo, bitabaye ibyo igihangano kizatwikwa byoroshye. Ubujyakuzimu bwinjira mugihe cyo gusudira cyahagaritswe ntigomba kurenza 2/3 byubugari bwisahani. Uburyo bukurikira bukoreshwa burashobora gukoreshwa muburyo bwo gusudira kuruhande rumwe no gusudira impande zombi (Ishusho 2-35):
1) Gusudira ku muringa. 2) Gusudira kuri paje yigihe gito. 3) Gusudira kuri flux pad. 4) Gusudira kuri padi ihoraho cyangwa gufunga hepfo gusudira. Kubijyanye no kwikorera imitwaro yibyuma bisudira byuma byububiko butandukanye, niba gutandukana kwububiko bwibisahani byombi birenze intera yagaragajwe mubisanzwe, ingano ya groove yatoranijwe ukurikije ubunini bwibisahani, cyangwa isahani yuzuye inanutse kuruhande rumwe cyangwa impande zombi kubyimbye kimwe nisahani yoroheje. Ibi birashobora kwirinda guhangayika biterwa nimpinduka zitunguranye mugice cyambukiranya kuri butt welding.
1) Ubunini bwemewe butandukanye bwububiko bwa plaque butandukanye bwerekanwe kumeza 2-1.
2) Uburebure. Iyo kunanuka kuruhande rumwe, uburebure ni 1/2 cyibyo iyo binaniye kuruhande rumwe, nkuko bigaragara ku gishushanyo Cyoroshye Uburebure L} 3 (s2 一 s}); iyo kunanuka kumpande zombi, kunanuka ni 2-34.
Iyo gusudira utubuto duhujwe nuburinganire buringaniye, insinga yo gusudira igomba kuba kumurongo wo hagati weld. Niba insinga yo gusudira idashyizwe hagati, irashobora gutera inenge nko kwinjira bituzuye no gusudira. Iyo gusudira utubuto twibibumbano byuburinganire butaringaniye, insinga yo gusudira igomba kubogama ku isahani yimbitse kugirango umuvuduko wacyo wo gushonga umeze nkuw'isahani yoroheje, kugirango isuderi ikorwe neza. Igicapo 2-31 cerekana guhagarika insinga zo gusudira kubice bifatanye.
Icyerekezo nubunini bwinsinga zo gusudira biratandukanye, kandi "arc blowing force" ningaruka zubushyuhe bwa arc kuri pisine yashongeshejwe nabyo biratandukanye, bitanga ingaruka zitandukanye kumiterere ya weld. Mu myitozo yo gusudira, ubugari bwa weld, ubushakashatsi bwashongeshejwe hamwe na coefficient de fonctionnement ya weld irashobora guhindurwa muguhindura icyerekezo nubunini bwinsinga zo gusudira. Ariko rero, hakwiye kwirindwa ko insinga yo gusudira ari nini cyane, bitabaye ibyo ikabyara imiterere mibi yo gusudira. Ingaruka z'icyerekezo n'ubunini bw'insinga zo gusudira ku gusudira byerekanwe ku gishushanyo cya 2-30.
Ibikoresho byo gusudira Xinfa bifite ibiranga ubuziranenge kandi buke. Ushaka ibisobanuro birambuye, nyamuneka sura:Abasudira & Gukata Inganda - Ubushinwa bwo gusudira & Gukata Uruganda & Abatanga isoko (xinfatools.com)
Kongera uburebure bwagutse bwinsinga yo gusudira muburyo bwo guhora gusudira birashobora kongera umuvuduko wo gusudira insinga zo gusudira kuri 25% kugeza kuri 50%, ariko mugihe ingufu za arc ari nkeya, ubujyakuzimu bwinjira nubugari bwa weld bizagabanuka. Imiterere ya weld yasuditswe hamwe ninsinga yo gusudira hamwe nuburebure bwagutse iratandukanye rwose nubwa weld weld hamwe ninsinga yo gusudira hamwe nuburebure busanzwe bwo kwaguka. Kubwibyo, mugihe hakenewe ubujyakuzimu bunini bwinjira, ntabwo ari byiza kongera uburebure bwagutse bwinsinga. Iyo uburebure bwagutse bwinsinga yo gusudira bwiyongereye kugirango wongere umuvuduko wo gusudira, umuvuduko wa arc ugomba kongerwa icyarimwe kugirango ugumane uburebure bukwiye bwa arc.
Kuzenguruka arc gusudira hamwe numurimo wo gushyushya insinga yo gusudira birashobora kongera umuvuduko wo gushonga wicyuma cyo gusudira hamwe nubunini bwinsinga zo gusudira bitarinze kongera ubushyuhe bwibikoresho fatizo, bityo bikagera ku ntego yo kuzamura imikorere yo gusudira. Uburebure bwagutse bw'insinga zo gusudira hamwe no gushyushya insinga zo gusudira byerekanwe ku gishushanyo cya 2-29.
Mubihe bimwe bya arc power power, impinduka mumuvuduko wo gusudira uhindure ubushyuhe bwinjiza bwa weld, bityo uhindure ubujyakuzimu n'ubugari. Iyo umuvuduko wo gusudira wihuse, kubera ubushyuhe bwa arc budahagije bwo gusudira, ubujyakuzimu bwa weld n'ubugari bizagabanuka cyane, igipimo cyo guhuza kizagabanuka, kandi mugihe gikomeye, inenge nko gukata, kwinjira bituzuye no guterwa ubwoba bizaterwa. Kubwibyo, mugihe wongereye umuvuduko wo gusudira, imbaraga za arc zigomba kongerwa kugirango uburebure bwa weld n'ubugari buhoraho. Igishushanyo 2-28 cyerekana ingaruka zumuvuduko wo gusudira kumiterere.
Mugihe cyo gusudira arc kurohama, voltage ya arc igenwa ukurikije ubunini bwumudozi wo gusudira, ni ukuvuga, mugihe runaka cyo gusudira, uburebure bwa arc bugomba guhora buhoraho kugirango barebe ko arc "yaka" neza kandi weld ikorwa muburyo bushyize mu gaciro . Ariko, ibihe bikurikira bigomba gufatwa ukundi:
1) Iyo ubuso bwubuso bwububiko butandukanye bwateranijwe nabi cyangwa ikinyuranyo cyumuzi wa butt weld nini cyane, voltage ya arc ntigomba kuba nto cyane. 2) Gusudira byimbitse ntigomba gusudwa hamwe na voltage yo hejuru ya arc. Imiterere yo gusudira yibice byihariye bihuye na arc voltage zitandukanye zerekanwa mubishusho 2-27.
Mubihe bimwe na bimwe, guhindura imiyoboro yo gusudira birashobora guhindura umuvuduko wo gushonga wicyuma cyo gusudira hamwe nuburebure bwimbitse bwa weld. Nyamara, kwiyongera cyane kumashanyarazi yo gusudira byanze bikunze biganisha ku burebure bukabije bwo gusudira hamwe nuburebure bwimbitse bwinjira, bikaviramo kwangirika kwimitsi. Muri icyo gihe, ubwo buryo bwo gusudira bukabije bwongera kugabanuka kwa weld, bityo bigatera inenge nko gusudira ibice, imyenge, gushyiramo ibice, hamwe na zone yibasiwe nubushyuhe bukabije hamwe no gusudira bikabije. Kubwibyo, mugihe wongereyeho gusudira, imbaraga za arc zigomba kongerwaho bikwiranye nuburyo bwiza bwo gusudira. Inenge yo gusudira ishobora guterwa numuyoboro mwinshi wo gusudira urerekanwa mumashusho 2-26.
