Kuweta kwa TIG kunapangidwa koyamba ku America (USA) mu 1936, komwe kumadziwika kuti Argon arc welding. TIG imalola kuti malo olumikizirana apangidwe bwino kwambiri ndi mpweya wopanda mpweya wokhala ndi zotsatira zoyera zoweta. Njira iyi yoweta ndi njira yoweta yogwiritsira ntchito zinthu zonse, makulidwe a khoma, ndi malo olumikizirana.
Ubwino wa njira yowotcherera iyi ndi kuti imatulutsa madzi ambiri komanso imatulutsa zinthu zochepa zodetsa komanso imatsimikizira kuti cholumikizira chapamwamba kwambiri chimagwiritsidwa ntchito bwino. Kupereka zinthu zogwiritsidwa ntchito zowotcherera ndi mphamvu yamagetsi sizimalumikizana, kotero izi zimapangitsa kuti TIG ikhale yoyenera kugwiritsa ntchito mizu yowotcherera komanso kuwotcherera pamalopo.
Komabe, TIG welding imafuna wowotcherera wophunzitsidwa bwino kuti agwiritse ntchito bwino ndi luso lake komanso wodziwa bwino kugwiritsa ntchito magetsi ndi amperage moyenera. Izi zithandiza kuti TIG welding ikhale yoyera komanso yabwino kwambiri. Ndipo ndikuganiza kuti izi ndi zomwe zimapangitsa kuti TIG welding ikhale yovuta.
Monga mukuonera pachithunzichi, mutakanikiza chosinthira cha tochi, mpweya umayamba kuyenda. Ndipo nsonga ya tochi ikakhudza pamwamba pa chitsulo, pamakhala njira yochepa yozungulira. Chifukwa cha kuchuluka kwa mphamvu yamagetsi pamwamba pa tochi, chitsulocho chimayamba kuuma pamalo pomwe chakhudzana ndipo arc imayaka, ndithudi, yokutidwa ndi mpweya woteteza.
KUKHAZIKITSA KUPIKITSA/KUYENDA KWA MPWEYA
Kuthamanga kwa mpweya kumakhala mu l/min ndipo kumadalira kukula kwa dziwe losungunula, kukula kwa elekitirodi, kukula kwa nozzle ya mpweya, mtunda wa nozzle kupita pamwamba pa chitsulo, kayendedwe ka mpweya wozungulira ndi mtundu wa mpweya woteteza.
Lamulo losavuta ndilakuti malita 5 mpaka 10 a mpweya woteteza ayenera kuwonjezeredwa ku argon ngati mpweya woteteza komanso ku ma diameter a tungsten electrode omwe amagwiritsidwa ntchito kwambiri, pamlingo wa 1 mpaka 4 mm pamphindi.
MALO A TOCHI
Monga momwe zilili mu MIG Welding, malo a tochi, mukagwiritsa ntchito njira ya TIG Welding, nawonso ndi ofunikira kwambiri. Malo a tochi ndi ndodo ya electrode zimakhudza zotsatira zosiyanasiyana za welding.
Electrode yokha ndi chinthu chogwiritsidwa ntchito polumikiza zitsulo chomwe chimagwiritsidwa ntchito polumikiza zitsulo ndi zitsulo za TIG. Zinthu zogwiritsidwa ntchito polumikiza zitsulo nthawi zambiri zimasankhidwa mofanana ndi mtundu wa chitsulo. Komabe, pazifukwa zachitsulo, ndikofunikira kuti zinthu zogwiritsidwa ntchito polumikiza zitsulo zisiyane ndi chitsulo chachikulu pamene zinthu zina zogwirizanitsa zitsulo zimagwiritsidwa ntchito.
Kubwerera ku malo a tochi. Mutha kugwiritsa ntchito malo osiyanasiyana a tochi ya TIG ndi ndodo ya electrode pamene mukulumikiza maulumikizidwe osiyanasiyana achitsulo. Chifukwa chake malo a tochi amadalira mtundu wa maulumikizidwe achitsulo. Ndikutanthauza kuti pali maulumikizidwe anayi oyambira achitsulo monga:
T- Joint
Malo Olumikizira Pakona
Chipinda cha Matako
Cholumikizira cha pakhosi
Mukhoza kugwiritsa ntchito zina mwa malo a tochi pa ntchito zomwe mukufuna kumaliza. Ndipo mukadziwa bwino malo osiyanasiyana a tochi yolumikizira zitsulo, ndiye kuti mutha kuphunzira za magawo a tochi.
MAGWARO OWOTCHERA
Posankha magawo olumikizirana, ziyenera kudziwika kuti mphamvu yokha ndiyo imayikidwa pa makina olumikizirana. Mphamvu yamagetsi imatsimikiziridwa ndi kutalika kwa arc, komwe kumasungidwa ndi wolumikizira.
Chifukwa chake, kutalika kwakukulu kwa arc kumafuna magetsi okwera a arc. Mphamvu yolumikizira ya 45 amperage pa mm ya makulidwe achitsulo imagwiritsidwa ntchito ngati mtengo wofotokozera mphamvu yokwanira kuti chitsulo cholumikizira chilowerere mokwanira.
