Gusudira imiyoboro idafite ibyuma mubisanzwe bigizwe no gusudira imizi, kuzuza gusudira no gusudira. Gusudira hepfo yumuyoboro wicyuma nigice cyingenzi cyane cyo gusudira ibyuma bidafite ingese. Ntabwo bifitanye isano gusa nubwiza bwumushinga, ahubwo bifitanye isano niterambere ryumushinga. Kugeza ubu, gusudira inyuma yumuyoboro wicyuma ugabanijwemo inzira ebyiri: kuzuza inyuma no kuzuza argon. Kurinda inyuma ya Argon bigabanijwemo insinga zikomeye + TIG inzira hamwe ninsinga zikomeye + TIG + impapuro zishonga amazi; inyuma idafite uburinzi bwuzuye argon igabanijwemo imigozi ya flux-cored backing and welding rod (coated wire) ushyigikira TIG gusudira.
Kuzenguruka hepfo ibyuma bidafite ingese mubisanzwe bifata inzira ya TIG. Ukurikije uko ibintu bimeze kurubuga, dushobora gukoresha uburyo bune bukurikira bwo gusudira hepfo.
01. Uburyo bwo guhagarika umwuka no kurinda ukoresheje imbaho zifunga inyuma (ni ukuvuga insinga ikomeye yo gusudira + TIG)
Iyo umuyoboro w'icyuma udafite ingese wateguwe, ingingo yo gusudira irashobora kuzunguruka no gusudira, kandi guhumeka biroroshye cyane. Muri iki gihe, isahani yo guhagarika ubusanzwe ikoreshwa mu guhagarika no guhumeka impande zombi zifatanije mu gusudira mu rwego rwo kurinda gusudira hepfo, kandi icyarimwe, uruhande rwo hanze rufunze igitambaro gifatika. kuzibira.
Iyo gusudira, inzira yo guhumeka hakiri kare no guhagarika gaze nyuma igomba gukurikizwa. Umwenda wo gufatira hanze urashwanyaguzwa mugihe cyo gusudira. Kubera ko isahani yo guhagarika igizwe na reberi nicyuma cyera, ntabwo byoroshye kwangirika, ubwo buryo rero bwo gusudira burashobora kwemeza neza imbere muri weld. Huzuyemo gaze ya argon kandi urebe neza ko ifite isuku, kugirango tumenye neza ko icyuma kiri imbere muri weld kitaba okiside, kandi urebe neza ubwiza bwinyuma.

Iyo icyambu gihamye cyumuyoboro wicyuma ushyizwemo kandi ugasudwa, biragoye guhumeka uruhande rwimbere, kandi impande zimwe ziroroshye guhagarika. Muri iki gihe, impapuro zishonga amazi + isahani yo guhagarika irashobora gukoreshwa mugushiraho ikimenyetso. Nukuvuga ko uruhande rworoshye guhumeka kandi rworoshe kuwukuraho rufunze ikibaho kibuzitira, kandi uruhande rutari rworoshye guhumeka kandi rugoye kuvanaho ikibaho cyahagaritswe hamwe nimpapuro zishonga amazi.
Mugihe cyo gusudira icyuma kidafite ingese, mubihe byinshi, ntihazaba umwuka uhumeka kumpande zombi. Muri iki gihe, uburyo bwo kurinda kurinda argon kuzuza imbere muri weld biba ikibazo kitoroshye. Mu iyubakwa nyirizina ku kibanza, dukoresha amazi-elegitoronike Uburyo bwo gufunga impapuro, guhumeka neza hagati yikidodo, no gushira hanze hamwe nigitambaro gifatika byakemuye neza ibibazo byavuzwe haruguru.
Iyo impapuro zishongesha amazi zikoreshwa mugushiraho umwuka, kubera ko guhumeka biva hagati yikizunguruka, mugihe cyanyuma cyo gufunga, umuyoboro woguhumeka ugomba gukururwa vuba, kandi argon isigaye imbere igomba gukoreshwa mukurinda, hepfo igomba kurangira vuba kandi umunwa ugomba gufungwa.
Hamwe nubu buryo, twakagombye kumenya ko impapuro zishonga mumazi zigomba kuba ebyiri, kandi zigomba kumanikwa neza, bitabaye ibyo impapuro zishonga mumazi zangirika byoroshye kandi zigwa, kandi gusudira imbere bizabura uburinzi bwa gaze ya argon, na okiside bizabaho, bigatuma weld ikata kandi ikongera gukingurwa. Gusudira ntibishobora kwemeza ubwiza bwo gusudira, ariko kandi bigira ingaruka zikomeye mugihe cyubwubatsi, bityo rero hagomba gukorwa igenzura rikomeye mbere yo gusudira, kandi impapuro zishonga amazi zigomba gushyirwaho.
Ahantu henshi hubakwa, twakoresheje ubu buryo bwo gusudira kugirango dushyigikire, ubwiza bwabwo burashobora kwemezwa neza, kandi biragoye no kubaka, bityo abasudira bitonze kandi bafite ubuhanga bagomba guhitamo iki gikorwa.
03. Uruhande rwinyuma ntirurinzwe na gaze ya argon, kandi flux cored wire + TIG ikoreshwa
Ubu buryo bwakoreshejwe mu gihugu cyacu imyaka itari mike, kandi hashyizweho insinga zo gusudira flux nka E308T1-1, E308LT1-1, E309T1-1, E309LT1-1, 347T1-1, E316T1-1, E316LT1-1 , kandi zashyizwe mubikorwa murwego rwo gusudira byageze ku nyungu zubukungu.
Kubera ko uruhande rwinyuma rutuzuye na argon, ibyiza byayo biragaragara, nkibikorwa byiza, ubworoherane, nigiciro gito, kandi birakwiriye gushyirwaho ahazubakwa. Ariko, kubera imiterere yabyo, insinga yo gusudira flux ifite amabara menshi asabwa gusudira mugihe ikora. Umuvuduko wacyo wo kugaburira insinga zirihuta kandi ukuri kugaburira insinga ni mwinshi, biragoye rero kumenya. Abasudira bagomba gutozwa byumwihariko nubuhanga mbere yuko bitabira gusudira. Muri Nanjing Yangba hamwe n’ahantu hubatswe n’amahanga, twakemuye neza ikibazo ko argon idashobora guhumeka ku cyambu cyinama no ku cyambu cyo gusana dukoresheje ubu buryo.
04. Uruhande rwinyuma ntirurinzwe na gaze ya argon, kandi insinga yo gusudira yubatswe (wire-flux-cored welding wire) + TIG inzira
Mu myaka ya za 90, Kobelco n'andi masosiyete yo mu Buyapani bakoze insinga zo gusudira hepfo. Mu myaka yashize, igihugu cyanjye cyateje imbere insinga zo gusudira zidafite ingese (ni ukuvuga insinga zo gusudira zometseho, nka TGF308, TGF308L, TGF309, TGF316L, TGF347, nibindi), kandi zikoreshwa mubwubatsi nyabwo, kandi zigera kubisubizo byiza, twakoresheje neza ubu buryo mumushinga wo kwagura no guhindura ubushobozi bwa Wupec.
Uburyo bwo gukingira ibyuma bifata ibyuma bidafite ingese + inzira ya TIG ni uko isudira yinyuma irinzwe nigikorwa cya metallurgjique hagati yigituba cyatewe no gusudira insinga zashonga hamwe nibintu byacyo bivangavanze, kandi gusudira imbere kurinzwe na argon, slag na alloy element .
Mugihe ukoresheje ubu buryo, ingingo zikurikira zigomba kwitabwaho: Mugihe cyo gusudira, hagomba kubaho inguni ikwiye hagati yigitereko cyo gusudira, insinga zo gusudira nigice cyo gusudira. Inguni nziza yinyuma yumudozi wo gusudira nozzle ni 70 ° -80 °, Inguni ni 15 ° -20 °; kugenzura neza ubushyuhe bwa pisine yashongeshejwe, hindura ubushyuhe bwa pisine yashongeshejwe uhindura inguni hagati yigitereko cyo gusudira no gusudira, guhindura umuvuduko wo gusudira, nibindi, kugirango umenye neza ko imiterere yo gusudira ari nziza (ubugari ni kimwe, ntagahunda, Convexity nizindi nenge);
Mugihe cyo gukora, ikigezweho kigomba kuba kinini cyane kuruta icyuma cyo gusudira insinga zikomeye, kandi ikiganza cyo gusudira kigomba guhindagurika gato kugirango byihutishe gutandukanya icyuma gishongeshejwe hamwe nigishishwa cyashongeshejwe, bikaba byoroshye kwitegereza ikidendezi cyashongeshejwe no kugenzura niba kwinjira ari byuzuye; mugihe wuzuza insinga zo gusudira, nibyiza kohereza muri 1/2 cya pisine yashongeshejwe, hanyuma ukande imbere imbere kugirango umenye neza imizi kandi wirinde kwinjirira;
Mugihe cyo gusudira, insinga yo gusudira igomba kugaburirwa no kuyisohokamo buri gihe, kandi insinga yo gusudira igomba guhora irinzwe na gaze ya argon, kugirango birinde ko insinga yo gusudira irangira kandi ikagira ingaruka ku bwiza bwo gusudira; Gusudira ahantu hagomba kuba ahantu hahanamye kuri 45 °, kandi hagomba kwitonderwa inenge nka crater arc na cavites zagabanutse mugihe ufunze arc.
Umugozi wo gusudira utwikiriye ukoreshwa mu gusudira hepfo, kandi gaze ya argon ntabwo ikoreshwa imbere muri weld. Imikorere yo gusudira iroroshye kandi byihuse, hamwe nibiranga imikorere ihanitse kandi igiciro gito. Ubu buryo bukoreshwa mu gusudira hamwe hamwe hamwe hamwe hamwe hamwe 28 hamwe, kandi igipimo cyo gutambuka inshuro imwe yo gusudira ni 100%), gikwiye kuzamurwa no gukoreshwa.
Uburyo bune bwo hejuru bwo gusudira ibyuma byo gusudira bifite inyungu zabyo nibibi. Mu bwubatsi nyabwo, ntitwakagombye gutekereza kubiciro byubwubatsi gusa, ahubwo tunareba ubwiza bwo gusudira niterambere ryubwubatsi dukurikije imiterere yihariye yikibanza, tugahitamo inzira yubwubatsi.
