Hanyar aikin walda ta Argon
Argon arc wani aiki ne wanda hannun hagu da dama ke motsawa lokaci guda, wanda yayi daidai da zana da'ira da hannun hagu da kuma zana murabba'i da hannun dama a rayuwarmu ta yau da kullun.Don haka, ana ba da shawarar cewa wadanda suka fara koyon walda na argon arc su sami irin wannan horon, wanda zai taimaka wajen koyon walda.
(1) Ciyarwar waya: raba zuwa cikawar waya ta ciki da cika waya ta waje.
Ana iya amfani da wayar filler na waje don fiddawa da cikawa.Yana amfani da babban halin yanzu.Shugaban waya na walda yana kan gaban tsagi.Hannun hagu yana tsunkule wayar walda kuma a ci gaba da aika shi cikin narkakken tafkin don walda.Ramin tsagi yana buƙatar ƙarami ko babu rata.
Amfaninsa shine babban aikin samarwa da ƙwarewar aiki mai sauƙi saboda babban rata na yanzu da ƙananan.Rashin hasara shi ne cewa idan an yi amfani da shi don ƙasa, saboda mai aiki ba zai iya ganin narkewar ɓacin rai ba da kuma ƙarfafa gefen baya, yana da sauƙi don samar da wanda ba a haɗa shi ba kuma ba samun kyakkyawan tsari ba.
Za'a iya amfani da wayar filler na ciki kawai don goyan bayan walda.Yi amfani da yatsan yatsan hannu, yatsan hannu ko yatsa na hannun hagu don daidaita aikin ciyar da waya.Yatsan yatsa da yatsan zobe suna matsa wayar walda don sarrafa alkibla.Wayar walda tana kusa da bakin bakin da ke cikin tsagi kuma ta narke tare da ƙwanƙwasa baki Don waldawa, ana buƙatar ratar tsagi ya fi diamita na wayar walda.Idan faranti ne, ana iya lankwasa wayar walda a cikin baka.
Amfaninsa shi ne, saboda wayar walda ta ke a kishiyar tsagi, ana iya ganin bakin ƙwanƙwasa da yanayin narkewar wayar a fili, kuma ana iya ganin ƙarfafawar baya daga hangen nesa na idanu, don haka weld fusion yana da kyau, kuma ana iya samun ƙarfafawar baya da rashin haɗin gwiwa.Rashin lahani shine aikin yana da wahala, kuma ana buƙatar mai walda don ƙarin ƙwarewar aiki.Domin tazarar tana da girma, ƙarar walda zata ƙaru daidai da haka.Ratar yana da girma, don haka halin yanzu yana da ƙasa, kuma ingancin aikin yana da hankali fiye da na waya filler na waje.
(2) Hannun walda sun kasu kashi-kashi na hannaye da mops.
Hannun girgiza shine a danna bututun walda dan kadan akan kabu na walda, kuma girgiza hannu sosai don walda.Amfaninsa shine saboda an danna bututun walda akan kabu na walda, kuma hannun walda yana da ƙarfi sosai yayin aiki, don haka kabu ɗin yana da kariya sosai, ingancin yana da kyau, bayyanar yana da kyau sosai, kuma ƙimar cancantar samfurin yana da girma. .Yana samun launi mai kyau sosai.Rashin hasara shi ne cewa yana da wuyar koyo, saboda hannu yana girgiza da yawa, don haka ba shi yiwuwa a yi walda a cikas.
Mop ɗin yana nufin cewa tip ɗin walda ya jingina da sauƙi ko baya jingina kan ɗinkin walda, ɗan yatsa ko zobe na hannun dama shima ya jingina ko baya jingina akan kayan aikin, hannu yana murɗa ƙarami, ya ja hannun walda. don walda.Amfaninsa shi ne cewa yana da sauƙin koyo kuma yana da kyakkyawar daidaitawa.Abin da ke damun sa shi ne, siffar da ingancin ba su girgiza da kyau ba, musamman don walda a sama ba tare da girgiza ba don sauƙaƙe walda.Yana da wahala a sami kyakkyawan launi da siffa lokacin walda bakin karfe.
(3) Arc ignition: Arc ignition yawanci ana amfani da shi (high-frequency oscillator ko high-frequency pulse generator), kuma tungsten electrode da weldment ba sa tuntuɓar don kunna baka.Lokacin da ba a kunna wuta ba, ana amfani da wutar lantarki ta lamba (mafi yawancin ana amfani da su a wuraren gine-gine) shigarwa, musamman ma tsayin tsayi), ana iya sanya jan karfe ko graphite akan ramin walda don buga baka, amma wannan hanyar ta fi girma. mai wahala da ƙarancin amfani.Gabaɗaya, bugun jini mai haske tare da wayar walda yana sanya walƙiya da lantarki na tungsten su zama gajere da sauri kuma suna yanke haɗin gwiwa.Kuma kunna baka.
(4) Welding: Bayan an kunna baka, dole ne a fara zafi na daƙiƙa 3-5 a farkon walda, sannan a fara ciyar da waya bayan an kafa tafkin narkakkar.Lokacin waldawa, ya kamata kusurwar fitilar walda ta dace, kuma a ciyar da wayar walda daidai gwargwado.Ya kamata fitilar walda ta ci gaba da kyau, ta karkata hagu da dama a hankali a hankali a ɓangarorin biyu, da ɗan sauri a tsakiya.Kula da hankali ga canje-canje na narkakken tafkin.Lokacin da narkakkar tafkin ya yi girma, kabu na walda ya zama mai faɗi, ko kuma kabu ɗin walda ya zama maɗaukaki, saurin walda ya kamata a ƙara ko kuma a sake rage ƙarfin walda.Lokacin da fusion na narkakken tafkin ba shi da kyau kuma ba za a iya ciyar da waya ba, wajibi ne don rage saurin walda ko ƙara yawan walda.Idan shi ne kasa waldi, idanu ya kamata mayar da hankali a kan m gefuna a bangarorin biyu na tsagi, da kuma sasanninta na idanu.Hasken gefe yana gefen kishiyar tsaga, kuma kula da canjin sauran tsayi.
5) Arc extinguishing: Idan baka yana kashe kai tsaye, yana da sauƙi don samar da rami mai raguwa.Idan fitilar walda tana da mai kunna baka, ya kamata a rufe baka na lokaci-lokaci ko kuma a daidaita shi zuwa daidaitaccen ramin baka.Ana jagorantar baka zuwa gefe ɗaya na tsagi, kuma ba a kafa rami mai raguwa ba.Idan rami na raguwa ya faru, dole ne a goge shi kafin walda.
Idan baka yana wurin haɗin gwiwa, yakamata a fara niƙa haɗin gwiwa a cikin wani bevel da farko, sa'an nan kuma welded gaba 10-20mm bayan haɗin gwiwa ya narke sosai, sa'an nan kuma an rufe baka a hankali, kuma babu wani rami mai raguwa da zai iya faruwa.A cikin samarwa, ana ganin sau da yawa cewa ba a goge haɗin gwiwa a cikin bevels, kuma lokacin walda na haɗin gwiwa yana tsawaita kai tsaye don haɗin gwiwa.Wannan mummunar dabi'a ce.Ta wannan hanyar, haɗin gwiwa yana da wuyar haɗuwa, haɗin da ba a haɗa su ba kuma gefen baya ya fita daga haɗin gwiwa, wanda zai shafi bayyanar siffar.Idan babban gami ne Kayan kuma yana da saurin fashewa.
