Gusudira umuringa
Uburyo bwo gusudira umuringa (ubusanzwe bwitwa umuringa usukuye mu nganda) burimo gusudira gazi, gusudira intoki za karuboni arc, gusudira intoki arc no gusudira intoki arc arc, hamwe nuburyo bunini bushobora no gusudira mu buryo bwikora.
1.Ibisanzwe bikoreshwa cyane gusudira gazi y'umuringa ni gusudira hamwe, hamwe no gufatanya hamwe na T bigomba gukoreshwa bike bishoboka. Ubwoko bubiri bw'insinga zo gusudira burashobora gukoreshwa mugusudira gaze. Imwe ni insinga yo gusudira irimo ibintu bya deoxygene, nk'insinga 201 na 202; ikindi ni insinga rusange y'umuringa hamwe no gukata ibice fatizo, naho agent ya 301 ikoreshwa nka flux. Umuriro utabogamye ugomba gukoreshwa mugihe gazi yo gusudira umuringa.
2.Umuringa wumuringa wicyuma wumuringa wumuringa 107 ukoreshwa mugusudira intoki arc, naho gusudira ni umuringa (T2, T3). Impande zo gusudira zigomba gusukurwa mbere yo gusudira. Iyo umubyimba wo gusudira urenze mm 4, gushyushya bigomba gushyuha mbere yo gusudira, kandi ubushyuhe bwo gushyuha buri hafi 400 ~ 500 ℃. Iyo gusudira hamwe n'umuringa 107 wo gusudira, amashanyarazi agomba guhindurwa na DC.
3.Imbuto ngufi zigomba gukoreshwa mugihe cyo gusudira, kandi inkoni yo gusudira ntigomba guhindagurika. Inkoni yo gusudira ikora umurongo ugaruka, ushobora kunoza imiterere ya weld. Urudodo rurerure rugomba gusudwa buhoro buhoro. Umuvuduko wo gusudira ugomba kwihuta bishoboka. Mugihe cyo gusudira ibice byinshi, icyapa kiri hagati yabyo kigomba kuvaho burundu. Gusudira bigomba gukorerwa ahantu hafite umwuka uhagije kugirango wirinde uburozi bw'umuringa. Nyuma yo gusudira, koresha inyundo-imitwe iringaniye kugirango ukande isuderi kugirango ukureho imihangayiko kandi uzamure ubwiza bwa weld.
4.Manual argon arc gusudira umuringa. Iyo intoki ya argon arc gusudira umuringa, insinga zikoreshwa ni insinga 201 (insinga idasanzwe yo gusudira umuringa) hamwe ninsinga 202, kandi ikoresha insinga z'umuringa, nka T2.
Mbere yo gusudira, firime ya oxyde, amavuta hamwe nundi mwanda kumpande zo gusudira kumurimo wakazi hamwe nubuso bwinsinga bigomba gusukurwa kugirango wirinde inenge nka pore hamwe nuduce twa slag. Uburyo bwo gukora isuku burimo gusukura imashini no gusukura imiti. Iyo umubyimba wibibabi bifatanye utageze kuri mm 3, bevel ntifungura; iyo umubyimba wibisahani ufite mm 3 kugeza kuri 10, hafunguwe umuvumo wa V, naho inguni ya 60 ni 70; iyo ubunini bw'isahani burenze mm 10, hafunguwe umuyonga wa X, Inguni ya bevel ni 60 ~ 70; kugirango wirinde kudasudwa, impande zidahwitse zisigaye. Ukurikije uburebure bwa plaque nubunini bwa bevel, ikinyuranyo cyo guteranya ikibuno cyatoranijwe kiri hagati ya 0.5 na 1.5 mm.
Intoki z'umuringa argon arc gusudira mubisanzwe ikoresha DC ihuza neza, ni ukuvuga tungsten electrode ihujwe na electrode mbi. Kugirango ukureho umwobo wo mu kirere no kwemeza guhuza kwizerwa no kwinjira mu mizi ya weld, ni ngombwa kongera umuvuduko wo gusudira, kugabanya ikoreshwa rya argon, no gushyushya gusudira. Iyo ubunini bw'isahani butageze kuri mm 3, ubushyuhe bwo gushyuha ni 150 ~ 300 ℃; iyo ubunini bw'isahani burenze mm 3, ubushyuhe bwo gushyuha ni 350 ~ 500 ℃. Ubushyuhe bwo gushyuha ntibukwiye kuba hejuru cyane, bitabaye ibyo imiterere yubukorikori bwingingo zasudiwe zizagabanuka.
Hariho kandi umuringa wa carbone arc gusudira, na electrode ikoreshwa mugusudira karubone arc irimo electrode ya karubone na electrode ya grafite. Umugozi wo gusudira ukoreshwa mu gusudira umuringa wa karubone arc ni kimwe nigihe cyo gusudira gaze. Ibikoresho fatizo birashobora kandi gukoreshwa mugukata imirongo, kandi flux yumuringa nka agent agent 301 irashobora gukoreshwa.
Gusudira umuringa
1.Uburyo bwo gusudira imiringa burimo: gusudira gaze, gusudira karubone arc, gusudira intoki arc hamwe no gusudira arc arc. 1.
Insinga zo gusudira zikoreshwa mu gusudira gazi z'umuringa zirimo: insinga 221, insinga 222 na wire 224. Izi nsinga zo gusudira zirimo ibintu nka silikoni, amabati, ibyuma, nibindi, bishobora gukumira no kugabanya guhumeka no gutwika zinc muri pisine yashongeshejwe, kandi bifasha kurinda gusudira. Imikorere no gukumira umwobo. Amazi akunze gukoreshwa mumuringa wo gusudira gaze harimo ifu ikomeye na gaz flux. Amazi ya gaz agizwe na aside ya boric methyl na methanol; fluxes ni nka agent ya gaze 301.
2.Ibikoresho bya arc byo gusudira umuringa Usibye umuringa 227 n'umuringa 237, inkoni zo gusudira mu rugo zishobora no gukoreshwa mu gusudira imiringa.
Iyo gusudira umuringa arc, gukoresha ingufu za DC uburyo bwiza bwo guhuza bigomba gukoreshwa kandi inkoni yo gusudira igomba guhuzwa na electrode mbi. Ubuso bwo gusudira bugomba gusukurwa neza mbere yo gusudira. Inguni ya bevel ntigomba kuba munsi ya 60 ~ 70o. Kugirango tunoze imiterere yo gusudira, ibice byo gusudira bigomba gushyuha kuri 150 ~ 250 ℃. Gusudira bigufi arc bigomba gukoreshwa mugihe gikora, nta gutambuka cyangwa imbere no gusubira inyuma, gusa umurongo ugenda, kandi umuvuduko wo gusudira ugomba kuba muremure. Ibice byo gusudira bikozwe mu muringa bihura n’ibitangazamakuru byangirika nkamazi yo mu nyanja na amoniya bigomba gushyirwaho nyuma yo gusudira kugirango bikureho ibibazo byo gusudira.
3.Manual argon arc gusudira imiringa. Intoki ya arcon arc gusudira imiringa irashobora gukoresha insinga zumuringa zisanzwe: wire 221, wire 222 na wire 224, nibikoresho bifite ibice bimwe nkibikoresho fatizo nabyo birashobora gukoreshwa nkibikoresho byuzuza.
Kuzenguruka birashobora gukorwa nubu buryo butaziguye cyangwa AC. Iyo ukoresheje gusudira AC, guhumeka kwa zinc biroroshye kuruta iyo umuyoboro utaziguye uhujwe. Mubisanzwe, gushyushya ntibikenewe mbere yo gusudira, kandi gushyushya ni mugihe gusa ubunini bwisahani ari bunini. Umuvuduko wo gusudira ugomba kwihuta bishoboka. Nyuma yo gusudira, ibice byo gusudira bigomba gushyukwa kuri 300 ~ 400 ℃ kugirango bifatanye kugirango bikureho imihangayiko yo gusudira kugirango wirinde gucikamo ibice byo gusudira mugihe ukoresheje.
4.Gusudira ibyatsi bya karubone Iyo gusudira umuringa wa karubone arc, insinga 221, insinga 222, insinga 224 nizindi nsinga zo gusudira byatoranijwe ukurikije ibice fatizo. Urashobora kandi gukoresha insinga zikozwe mu muringa zo gusudira. Umukozi wa gaze 301 cyangwa ibisa nabyo birashobora gukoreshwa nka flux mugusudira. Gusudira bigomba gukoreshwa arc ngufi kugirango bigabanye umwuka wa zinc no gutwika ibyangiritse.
