Igitekerezo no gutondekanya ibyuma bya gaz arc gusudira
Uburyo bwo gusudira arc bukoresha electrode yashongeshejwe, gaze yo hanze nkigikoresho cya arc, kandi ikarinda ibitonyanga byicyuma, pisine yo gusudira hamwe nicyuma cyo hejuru cyane muri zone yo gusudira bita gazi ya elegitoronike ya gaz ikingiwe arc welding.
Ukurikije ibyiciro byo gusudira, birashobora kugabanywamo ibice bikomeye byo gusudira hamwe na flux cored wire. Gazi ya inert (Ar cyangwa He) ikingiye uburyo bwo gusudira arc ikoresheje insinga zikomeye bita Melting Inert Gas Arc Welding (MIG Welding); uburyo bwa argon bukungahaye kuri gaz ikingira arc gusudira hakoreshejwe insinga ikomeye yitwa Metal Inert Gas Arc Welding (MIG welding). MAG gusudira (Metal Active Gas Arc Welding). CO2 gaze ikingira gusudira ikoresheje insinga zikomeye, bita gusudira CO2. Iyo ukoresheje insinga zifite amabara ya flux, gusudira arc bishobora gukoresha gaze ivanze ya CO2 cyangwa CO2 + Ar nkuko gaze ikingira yitwa flux-cored wire gazi ikingira gusudira. Birashoboka kandi kubikora utongeyeho gaze ikingira. Ubu buryo bwitwa kwikingira arc gusudira.
Ibikoresho byo gusudira Xinfa bifite ibiranga ubuziranenge kandi buke. Ushaka ibisobanuro birambuye, nyamuneka sura:Abasudira & Gukata Inganda - Ubushinwa bwo gusudira no gutema uruganda & abatanga ibicuruzwa (xinfatools.com)
Itandukaniro riri hagati yo gusudira MIG / MAG hamwe no gusudira CO2
Ibiranga gusudira CO2 ni: igiciro gito kandi cyiza cyane. Ariko, ifite ibibi byubwinshi bwa spatter hamwe no kubumba nabi, kuburyo inzira zimwe zo gusudira zikoresha gusudira bisanzwe MIG / MAG. Ubusanzwe MIG / MAG gusudira nuburyo bwo gusudira arc burinzwe na gaze ya inert cyangwa gaze ikungahaye kuri argon, ariko gusudira CO2 bifite imbaraga za okiside ikomeye, igena itandukaniro nibiranga byombi. Ugereranije no gusudira CO2, ibyiza byingenzi byo gusudira MIG / MAG ni ibi bikurikira:
1) Umubare wo gusebanya wagabanutse kurenga 50%. Arc yo gusudira irinzwe na argon cyangwa gaze ikungahaye kuri argon irahagaze. Ntabwo arc ihagaze gusa mugihe cyo gutembera no guhinduranya indege, ariko kandi no mugihe gito cyumuzunguruko mugihe gito cyo gusudira kwa MAG, arc ifite ingaruka ntoya yo kwanga ibitonyanga, bityo ikemeza MIG / Ingano ya spatter yatewe MAG gusudira mugihe gito inzibacyuho yagabanutse kurenga 50%.
2) Ubudodo bwo gusudira buringaniye kandi bwiza. Kubera ko ihererekanyabubasha rya MIG / MAG gusudira ibitonyanga ari bimwe, byoroshye, kandi bihamye, gusudira bikorwa kimwe kandi cyiza.
3) Irashobora gusudira ibyuma byinshi bikora hamwe na alloys. Umutungo wa okiside wikirere cya arc urakomeye cyane cyangwa ntukabe oxyde. Gusudira kwa MIG / MAG ntibishobora gusa gusudira ibyuma bya karubone hamwe nicyuma kinini kivanze, ariko kandi nicyuma kinini gikora hamwe nuruvange rwarwo, nka: aluminium na aluminiyumu, ibyuma bitagira umwanda hamwe nudukoresho twinshi, Magnesium na magnesium, nibindi, nibindi.
4) Kunoza cyane uburyo bwo gusudira, ubwiza bwo gusudira no gukora neza.
Itandukaniro riri hagati yo gusudira MIG / MAG no gusudira bisanzwe MIG / MAG
Impapuro nyamukuru zoherejwe muburyo busanzwe bwa MIG / MAG gusudira ni ihererekanyabubasha ryumuvuduko mwinshi hamwe nigihe gito cyoherejwe kumashanyarazi make. Kubwibyo, umuyoboro muke uracyafite ibibi byubwinshi bwa spatter hamwe no gushushanya nabi, cyane cyane ibyuma bikora ntibishobora gusudwa munsi yumuyaga muke. Gusudira nka aluminium na alloys, ibyuma bidafite ingese, nibindi. Igitonyanga cyacyo cyoherejwe kiranga nuko buri pulse ihinduranya igitonyanga kimwe. Mubyukuri, ni ihererekanyabubasha. Ugereranije no gusudira bisanzwe MIG / MAG, ibintu byingenzi byingenzi ni ibi bikurikira:
1) Uburyo bwiza bwo kohereza ibitonyanga kuri pulse MIG / MAG gusudira ni uguhindura igitonyanga kimwe kuri pulse. Muri ubu buryo, muguhindura inshuro ya pulse, umubare wibitonyanga byimuwe mugihe cyumwanya urashobora guhinduka, aribwo umuvuduko wo gushonga wicyuma cyo gusudira.
2) Bitewe no gutonyanga kwa pulse imwe nigitonyanga kimwe, diameter yigitonyanga ihwanye hafi na diameter ya wire yo gusudira, bityo ubushyuhe bwa arc bwigitonyanga buri hasi, ni ukuvuga ubushyuhe bwigitonyanga buri hasi (ugereranije no kohereza indege no kohereza ibitonyanga binini). Kubwibyo, coefficente yo gushonga ya wire yo gusudira yiyongereye, bivuze ko gushonga kwinsinga yo gusudira byateye imbere.
3) Kuberako ubushyuhe bwigitonyanga buri hasi, habaho umwotsi wo gusudira. Ibi kuruhande rumwe bigabanya igihombo cyo gutwika ibintu bya alloy naho kurundi ruhande biteza imbere ibidukikije.
Ugereranije no gusudira bisanzwe MIG / MAG, ibyiza byayo ni ibi bikurikira:
1) Gusudira gusudira ni bito cyangwa nta na spatter.
2) Arc ifite icyerekezo cyiza kandi ikwiriye gusudira mumyanya yose.
3) Urudodo rwakozwe neza, ubugari bwo gushonga ni bunini, ibiranga urutoki rumeze nk'urutoki, kandi uburebure busigaye ni buto.
4) Umuyoboro muto urashobora gusudira neza ibyuma bikora (nka aluminium na alloys, nibindi).
Yaguye urwego rugezweho rwa MIG / MAG gusudira indege. Mugihe cyo gusudira kwa pulse, imiyoboro yo gusudira irashobora kugera ku ihererekanyabubasha ryimuka riva hafi yikintu gikomeye cyo kohereza indege kumurongo munini wa amps mirongo.
Duhereye hejuru, turashobora kumenya ibiranga nibyiza bya pulse MIG / MAG, ariko ntakintu gishobora kuba cyuzuye. Ugereranije na MIG / MAG isanzwe, amakosa yayo ni aya akurikira:
1) Gusudira umusaruro neza birasanzwe byunvikana ko ari bike.
2) Ibisabwa ubuziranenge kubasudira ni hejuru.
3) Kugeza ubu, igiciro cyibikoresho byo gusudira kiri hejuru.
Inzira nyamukuru ibyemezo byo guhitamo pulse MIG / MAG gusudira
Urebye ibisubizo byavuzwe haruguru byo kugereranya, nubwo gusudira MIG / MAG gusudira bifite ibyiza byinshi bidashobora kugerwaho ugereranije nubundi buryo bwo gusudira, bufite kandi ibibazo byibiciro byibikoresho byo hejuru, umusaruro muke muke, hamwe ningorabahizi kubasudira kumenya. Kubwibyo, guhitamo pulse MIG / MAG gusudira bigenwa ahanini nibisabwa byo gusudira. Ukurikije ibipimo ngenderwaho byo gusudira murugo muri iki gihe, gusudira bikurikira bigomba ahanini gukoresha pulse MIG / MAG gusudira.
1) Ibyuma bya karubone. Ibihe bisabwa cyane kubijyanye no gusudira no kugaragara cyane cyane mubikorwa byubwato bwumuvuduko, nka boiler, guhinduranya ubushyuhe bwimiti, guhinduranya ubushyuhe bwo hagati yubushyuhe bwo guhumeka, hamwe na turbine mumashanyarazi.
2) Icyuma. Koresha imigezi mito (munsi ya 200A yitwa imigezi mito hano, kimwe kimwe hepfo) hamwe nibihe bisabwa cyane kumiterere ya weld no kugaragara, nka lokomoteri hamwe nubwato bwumuvuduko mubikorwa bya chimique.
3) Aluminium n'ibiyikomokaho. Koresha amashanyarazi mato (munsi ya 200A yitwa amashanyarazi mato hano, kimwe hepfo aha) hamwe nibihe bisabwa cyane kumiterere ya weld no kugaragara, nka gari ya moshi yihuta, guhinduranya amashanyarazi menshi, gutandukanya ikirere nizindi nganda. Cyane cyane gariyamoshi yihuta, harimo CSR Group Sifang Rolling Stock Co., Ltd., Uruganda rwa Tangshan Rolling Stock, Imodoka za Gariyamoshi za Changchun, nibindi, hamwe nabakora inganda nto zitanga kubatunganyiriza. Nk’uko amakuru aturuka mu nganda abivuga, mu 2015 umurwa mukuru w’intara n’imijyi ituwe n’abaturage barenga 500.000 mu Bushinwa bizaba bifite gari ya moshi. Ibi birerekana ko hakenewe gari ya moshi nyinshi, kimwe no gukenera akazi ko gusudira hamwe nibikoresho byo gusudira.
4) Umuringa n'ibivange. Ukurikije imyumvire iriho ubu, umuringa hamwe nudukoresho twinshi dukoresha gusudira MIG / MAG gusudira (murwego rwo gusudira arc arc welding).
