1. Wane nadi zan yi amfani da shi, kuma ta yaya zan saita tashin hankali?
Girman waya da nau'in walda yana ƙayyade ma'aunin tuƙi don samun santsi, daidaitaccen ciyarwar waya. Akwai zaɓuɓɓuka gama gari guda uku: V-knurled, U-groove da V-groove.
Haɗa iskar gas- ko wayoyi masu garkuwa da kai tare da naɗaɗɗen tuƙi mai V-knured. Waɗannan wayoyi na walda suna da laushi saboda ƙirar tubular su; haƙoran da ke kan tuƙi suna ɗaukar waya suna tura shi ta hanyar injin ciyarwa. Yi amfani da juzu'in tuƙi na U-groove don ciyar da wayar walda ta aluminum. Siffar waɗannan juzu'in na'urar tana hana lalata wannan waya mai laushi. V-groove drive rolls shine mafi kyawun zaɓi don waya mai ƙarfi.
Don saita tashin hankali na abin tuƙi, fara fitar da naɗaɗɗen tuƙi. A hankali ƙara tashin hankali yayin ciyar da waya cikin hannun safar hannu.

A yayin aiwatar da aikin, ajiye bindigar a tsaye kamar yadda zai yiwu don guje wa ƙulla kebul ɗin, wanda zai iya haifar da ƙarancin ciyarwar waya.
Bin wasu mafi kyawun ayyuka masu alaƙa da wayar walda, jujjuyawar tuƙi da iskar gas na iya taimakawa wajen tabbatar da kyakkyawan sakamako a cikin tsarin waldawar MIG.
2. Ta yaya zan sami kyakkyawan sakamako daga wayar walda ta MIG?
Wayoyin walda na MIG sun bambanta da halayensu da sigogin walda. Koyaushe bincika ƙayyadaddun bayanan waya ko takardar bayanai don sanin menene amperage, ƙarfin lantarki da ciyarwar waya ke saurin mai ƙera ƙarfe ya ba da shawarar. Takaddun takaddun takaddun ana jigilar su tare da wayar walda, ko kuna iya zazzage su daga gidan yanar gizon masana'anta karfe. Waɗannan takaddun kuma suna ba da buƙatun iskar gas na garkuwa, da kuma nisan tuntuɓar aiki (CTWD) da faɗaɗa wayan walda ko shawarwarin tsayawa.
Stickout yana da mahimmanci musamman don samun sakamako mafi kyau. Tsawon tsayin sanda yana haifar da walƙiya mai sanyi, yana sauke amperage kuma yana rage shigar haɗin gwiwa. Gajeren sanda yakan samar da ingantacciyar baka mai ƙarfi da mafi ƙarancin ƙarancin wutar lantarki. A matsayinka na babban yatsan yatsa, mafi kyawun tsayin sanda shine mafi guntu wanda aka yarda don aikace-aikacen.
Ma'ajiyar walda mai kyau da sarrafa waya shima yana da mahimmanci ga kyakkyawan sakamakon walda na MIG. Ajiye spool a cikin busasshiyar wuri, saboda danshi na iya lalata wayar kuma yana iya haifar da fashewar hydrogen. Yi amfani da safar hannu lokacin sarrafa waya don kare shi daga danshi ko datti daga hannunka. Idan wayar tana kan mai ba da waya, amma ba a yi amfani da ita ba, rufe spool ko cire shi kuma sanya shi a cikin jakar filastik mai tsabta.
3. Wane hutu zan yi amfani da shi?
Lokacin hutun tuntuɓar lamba, ko matsayin tip ɗin tuntuɓar a cikin bututun walda na MIG, ya dogara da yanayin walda, waya walda, aikace-aikace da iskar gas ɗin kariya da kuke amfani da su. Gabaɗaya, yayin da halin yanzu ke ƙaruwa, hutun titin tuntuɓa ya kamata kuma ya ƙaru. Ga wasu shawarwari.
Wurin hutun 1/8- ko 1/4-inch yana aiki da kyau don walƙiya sama da amps 200 a cikin walƙiyar feshi ko walƙiya mai ƙarfi na yanzu, lokacin amfani da waya mai ƙarfe da iskar kariya ta argon. Kuna iya amfani da sandar waya na 1/2 zuwa 3/4 inci a cikin waɗannan yanayin.
Rike titin tuntuɓar ku tare da bututun ƙarfe yayin walda ƙasa da amps 200 a cikin gajeriyar kewayawa ko yanayin bugun jini mara ƙarfi na yanzu. Ana ba da shawarar ƙwanƙwasa igiya 1/4- zuwa 1/2-inch. A 1/4-inch tsaya a cikin gajeren kewayawa, musamman, yana ba ku damar walƙiya akan kayan da ba su da ƙarfi tare da ƙarancin ƙonawa ko warping.
Lokacin walda mahaɗin da ke da wuyar isa kuma a ƙasa da 200 amps, zaku iya tsawaita tip ɗin lamba 1/8 inch daga bututun ƙarfe kuma amfani da sandar 1/4-inch. Wannan saitin yana ba da damar samun dama ga hanyoyin haɗin kai masu wahala, kuma yana aiki da kyau don gajeriyar kewayawa ko yanayin bugun jini mara ƙarfi na yanzu.
Ka tuna, hutun da ya dace shine mabuɗin don rage damar da za a iya samu na porosity, rashin isashen shiga da konewa da kuma rage tazara.
Madaidaicin lamba tip matsayi na hutu ya bambanta bisa ga aikace-aikacen. Ka'ida ta gaba ɗaya: Yayin da halin yanzu ke ƙaruwa, hutun ya kamata kuma ya ƙaru.
4. Wane iskar gas ɗin kariya ce ta fi dacewa ga waya ta walda ta MIG?
Gas ɗin kariya da kuka zaɓa ya dogara da waya da aikace-aikacen. CO2 yana ba da shiga mai kyau lokacin walda kayan kauri, kuma zaku iya amfani da shi akan kayan sirara tunda yana ƙoƙarin yin sanyaya, wanda ke rage haɗarin ƙonewa. Don ƙarin shigar walda da haɓaka aiki mai yawa, yi amfani da haɗin iskar gas na kashi 75 na argon/25 bisa dari CO2. Wannan haɗin kuma yana samar da ƙarancin spatter fiye da CO2 don haka akwai ƙarancin tsaftacewa bayan walda.
Yi amfani da iskar kariya na CO2 kashi 100 ko kashi 75 CO2/25 na haɗin argon a haɗe tare da igiyar ƙarfe mai ƙarfi na carbon. Aluminum walda waya na bukatar argon garkuwa gas, yayin da bakin karfe waya aiki mafi kyau tare da tri-mix na helium, argon da CO2. Koyaushe ka yi la'akari da takamaiman takaddar waya don shawarwari.
5. Wace hanya ce mafi kyau don sarrafa kududdufin weld dina?
Ga kowane matsayi, yana da kyau a kiyaye wayar walda ta nufi babban gefen kududdufin walda. Idan kuna waldawa daga matsayi (a tsaye, a kwance ko sama), kiyaye kududdufin weld ƙarami yana ba da iko mafi kyau. Hakanan yi amfani da mafi ƙarancin diamita na waya wanda har yanzu zai cika haɗin haɗin walda sosai.
Kuna iya auna shigarwar zafi da saurin tafiye-tafiye ta ƙwanƙwasa walda da aka samar da daidaita daidai don samun ingantacciyar sarrafawa da kyakkyawan sakamako. Misali, idan kun samar da ƙwanƙolin walda wanda yake da tsayi da yawa da fata, yana nuna cewa shigar da zafi ya yi ƙasa da ƙasa kuma/ko saurin tafiyarku ya yi sauri.

Daidaita sigogi da dabarun ku daidai don cimma kyakkyawan walƙiya, wanda ke da ƙaramin kambi wanda kawai ya taɓa ƙarfen da ke kewaye da shi.
Waɗannan amsoshin tambayoyin da ake yi akai-akai sun taɓa kaɗan ne kawai daga cikin mafi kyawun ayyuka don walda MIG. Koyaushe bi hanyoyin walda don samun kyakkyawan sakamako. Hakanan, yawancin kayan walda da masana'antun waya suna da lambobin goyan bayan fasaha don tuntuɓar tambayoyi. Za su iya zama kyakkyawan hanya a gare ku.
