Kodi kuwotcherera TIG ndi chiyani: Mfundo, Ntchito, Zida, Ntchito, Ubwino ndi Kuipa

Lero tiphunzira za TIG kuwotcherera mfundo yake, ntchito, zipangizo, ntchito, ubwino ndi kuipa ndi chithunzi chake.TIG imayimira kuwotcherera kwa gasi wa tungsten kapena nthawi zina kuwotcherera kumeneku kumadziwika kuti kuwotcherera kwa gas tungsten arc.Pakuwotcherera uku, kutentha komwe kumafunikira kupanga weld kumaperekedwa ndi arc yamphamvu kwambiri yamagetsi yomwe imakhala pakati pa tungsten elekitirodi ndi chidutswa chogwirira ntchito.Pa kuwotcherera uku amagwiritsidwa ntchito electrode yosagwiritsidwa ntchito yomwe sisungunuka.Nthawi zambiri palibe zinthu zodzaza zomwe zimafunikira mu izimtundu wa kuwotchererakoma ngati pangafunike, ndodo yowotcherera imadyetsedwa mu weld zone mwachindunji ndikusungunuka ndi chitsulo m'munsi.Kuwotcherera uku kumagwiritsidwa ntchito kwambiri pakuwotcherera aluminium alloy.

TIG Welding Mfundo:

TIG kuwotcherera kumagwira ntchito pa mfundo yomweyo yakuwotcherera arc.Mu njira yowotcherera ya TIG, arc yolimba kwambiri imapangidwa pakati pa tungsten electrode ndi chidutswa chogwirira ntchito.Mu kuwotcherera uku nthawi zambiri gawo logwirira ntchito limalumikizidwa ku terminal yabwino ndipo ma elekitirodi amalumikizidwa ndi terminal.Arc iyi imapanga mphamvu ya kutentha yomwe imagwiritsidwanso ntchito kulumikiza mbale zachitsulofusion kuwotcherera.Gasi wotchinga amagwiritsidwanso ntchito omwe amateteza weld pamwamba ku oxidization.

Gwero la Mphamvu Zazida:

Chigawo choyamba cha zida ndi gwero lamagetsi.Gwero lamphamvu lomwe likufunika pakuwotcherera kwa TIG.Imagwiritsa ntchito gwero lamagetsi la AC ndi DC.Nthawi zambiri DC yamakono imagwiritsidwa ntchito ngati zitsulo zosapanga dzimbiri, Mild Steel, Copper, Titanium, Nickel alloy, ndi zina zambiri.Gwero lamagetsi limakhala ndi thiransifoma, chowongolera komanso zowongolera zamagetsi.Nthawi zambiri 10 - 35 V imafunika pa 5-300 A pakalipano pakupanga ma arc oyenera.

TIG Torch:

Ndi gawo lofunikira kwambiri pakuwotcherera kwa TIG.Muuni uwu uli ndi magawo atatu akulu, ma elekitirodi a tungsten, ma collets ndi nozzle.Tochi imeneyi mwina ndi madzi utakhazikika kapena mpweya utakhazikika.Mu tochi iyi, collet imagwiritsidwa ntchito kunyamula tungsten electrode.Izi zimapezeka m'mimba mwake mosiyanasiyana malinga ndi mainchesi a tungsten electrode.Mphunoyi imalola kuti arc ndi mpweya wotetezedwa uziyenda muzowotcherera.Mbali yopingasa ya nozzle ndi yaying'ono yomwe imapereka arc yolimba kwambiri.Pali madutsa a mpweya wotetezedwa pa nozzle.Mphuno ya TIG iyenera kusinthidwa nthawi ndi nthawi chifukwa imatha chifukwa cha kuwala kwamphamvu.

Dongosolo Lothandizira Gasi:

Nthawi zambiri argon kapena mpweya wina wa inert umagwiritsidwa ntchito ngati mpweya wotetezedwa.Cholinga chachikulu cha mpweya wotetezedwa kuteteza weld ku oxidization.Mpweya wotetezedwa sulola mpweya wobwera kapena mpweya wina kulowa m'malo owotcherera.Kusankhidwa kwa gasi wa inert kumatengera zitsulo zoti ziwotchedwe.Pali kachitidwe komwe kamayang'anira kutuluka kwa gasi wotetezedwa ku zone welded.

Zida Zodzaza:

Nthawi zambiri pakuwotcherera mapepala owonda palibe zinthu zodzaza zomwe zimagwiritsidwa ntchito.Koma kwa weld wandiweyani, zinthu zodzaza zimagwiritsidwa ntchito.Zinthu zodzaza zimagwiritsidwa ntchito ngati ndodo zomwe zimadyetsedwa mwachindunji ku weld zone pamanja.

Ntchito:

Kugwira ntchito kwa kuwotcherera kwa TIG kungafotokozedwe mwachidule motere.

• Choyamba, magetsi otsika kwambiri omwe amaperekedwa ndi gwero lamagetsi ku electrode yowotcherera kapena tungsten electrode.Zambiri, ndi
  Electrode imalumikizidwa ku terminal yoyipa ya gwero lamagetsi ndi gawo logwirira ntchito ku terminal yabwino.
• Izi zomwe zimaperekedwa panopa zimapanga phokoso pakati pa tungsten electrode ndi ntchito.Tungsten ndi electrode yosagwiritsidwa ntchito, yomwe imapatsa arc kwambiri.Chipilalachi chimatulutsa kutentha komwe kumasungunula zitsulo zoyambira kupanga zowotcherera.
• Mipweya yotetezedwa ngati argon, helium imaperekedwa kudzera mu valavu yokakamiza ndi valavu yowongolera ku tochi yowotcherera.Mipweya iyi imapanga chishango chomwe sichilola mpweya ndi mpweya wina uliwonse kulowa mu weld zone.Mipweya iyi imapanganso plasma yomwe imawonjezera kutentha kwa arc yamagetsi motero imakulitsa luso la kuwotcherera.
• Pakuwotcherera zinthu zopyapyala palibe chitsulo chodzaza chomwe chimafunikira koma popanga cholumikizira chokhuthala ndi zinthu zina zomwe zimagwiritsidwa ntchito ngati ndodo zomwe zimadyetsedwa pamanja ndi wowotcherera ku zone.

Ntchito:

• Nthawi zambiri amagwiritsidwa ntchito powotcherera ma aluminiyamu ndi ma aluminiyamu aloyi.
• Amagwiritsidwa ntchito powotcherera chitsulo chosapanga dzimbiri, aloyi wa kaboni, aloyi yamkuwa, aloyi ya nickel base etc.
• Amagwiritsidwa ntchito kuwotcherera zitsulo zosiyana.
• Amagwiritsidwa ntchito kwambiri m'mafakitale apamlengalenga.

Ubwino ndi Kuipa kwake:

Ubwino:

• TIG imapereka mgwirizano wolimba kwambiri poyerekeza ndi kuwotcherera kwa shield arc.
• Mgwirizanowu umalimbana ndi dzimbiri komanso ductile.
• Kuwona kwakukulu kwa mapangidwe ophatikizana kungapangidwe.
• Sichifuna kusinthasintha.
• Ikhoza kupangidwa mosavuta.
• Kuwotcherera uku ndikoyenera pamapepala owonda.
• Zimapereka mapeto abwino chifukwa chachitsulo chosasunthika kapena zitsulo zowotcherera zomwe zimawononga pamwamba.
• Cholowa chopanda cholakwika chimatha kupangidwa chifukwa cha electrode yosagwiritsidwa ntchito.
• Kuwongolera kwambiri pa kuwotcherera chizindikiro poyerekeza ndi kuwotcherera kwina.
• Ma AC ndi DC apano amatha kugwiritsidwa ntchito ngati magetsi.

Zoyipa:

• Chitsulo makulidwe kuti weld ndi malire 5 mm.
• Zinafunikira ntchito yaluso kwambiri.
• Mtengo woyamba kapena woyikira ndi wokwera poyerekeza ndi kuwotcherera kwa arc.
• Ndi pang'onopang'ono kuwotcherera ndondomeko.

Izi ndizokhudza kuwotcherera kwa TIG, mfundo, ntchito, zida, kugwiritsa ntchito, zabwino ndi zovuta zake.Ngati muli ndi funso lokhudza nkhaniyi, funsani poyankhapo.Ngati mumakonda nkhaniyi, osayiwala kugawana nawo pamasamba anu ochezera.Lembani tchanelo chathu kuti mupeze zolemba zambiri zosangalatsa.Zikomo powerenga.
