kuwotchererampweya woteteza wosakanikiranayapangidwa kuti iwonjezere ubwino wa ma weld. Mpweya wofunikira pa mpweya wosakanikirana ndi womwenso ndi mpweya wodziwika bwino woteteza ma weld mongampweya, mpweya woipa, argon, ndi zina zotero. Kugwiritsa ntchito mpweya wosakaniza m'malo mwa mpweya umodzi poteteza kuwotcherera kumathandizira kwambiri kuyeretsa madontho osungunuka, kulimbikitsa kusalala kwa weld, kukonza mapangidwe, ndikuchepetsa liwiro la ma pores, ndipo ndikodziwika kwambiri m'mafakitale owotcherera, odulira ndi mafakitale ena.

Pakadali pano, zomwe zimagwiritsidwa ntchito kwambirimpweya wosakanikiranaikhoza kugawidwa m'magasi osakanikirana a binary ndi magasi osakanikirana a ternary malinga ndi mtundu wa gasi wosakanikirana.

Kawirikawiri, zofunikira za mtundu wa weld zimakhala zapamwamba, ndipo kuyera kwa mpweya umodzi womwe umagwiritsidwa ntchito pokonzekera mpweya kumawonjezeka.mpweya wosakaniza.

Mpweya Wosakaniza Mbali Ziwiri

Argon+Oxygen

Kuwonjezera kuchuluka koyenera kwampweyaKuyika argon kungathandize kwambiri kukhazikika kwa arc ndikuyeretsa madontho osungunuka. Mphamvu zothandizira kuyaka kwa okosijeni zimatha kuwonjezera kutentha kwa chitsulo mu dziwe losungunuka, kulimbikitsa kuyenda kwa chitsulo, kuchepetsa zolakwika pakuwotcherera, kupangitsa kuti chowotcherera chikhale chosalala, ndikufulumizitsa liwiro la kuwotcherera ndikuwonjezera magwiridwe antchito a kuwotcherera. Kuphatikiza apo, mpweya woteteza mpweya ndi argon uli ndi ntchito zambiri ndipo ungagwiritsidwe ntchito kuwotcherera chitsulo cha kaboni, chitsulo chotsika cha alloy ndi chitsulo chosapanga dzimbiri cha makulidwe osiyanasiyana.

Argon + Mpweya Woipa

Mpweya wa kaboni dayokisaidi umatha kulimbitsa mphamvu ya weld komanso kukana dzimbiri, koma mpweya woteteza kaboni dayokisaidi umathira kwambiri, zomwe sizingathandize ogwira ntchito. Kusakaniza ndi argon yokhazikika kungachepetse bwino kuchuluka kwa chitsulo chomwe chimathira. Kugwiritsa ntchito mpweya woteteza mpweya wa okosijeni + argon kuli ndi ubwino woonekeratu pakuthira chitsulo cha kaboni ndi chitsulo chosapanga dzimbiri.

Argon + haidrojeni

HaidrojeniNdi mpweya wochepetsa kuyaka womwe sungangowonjezera kutentha kwa arc, kufulumizitsa liwiro la welding, ndikuletsa kudulidwa molakwika, komanso kuchepetsa mwayi wopanga ma CO pores ndikuletsa zolakwika za welding. Uli ndi zotsatira zabwino kwambiri pa welding pa ma alloys okhala ndi nickel, ma alloys a nickel-copper, ndi chitsulo chosapanga dzimbiri.

Zigawo Zitatu za Gasi Wosakaniza

Argon+Oxygen+Carbon Dioxide

Uwu ndi mpweya wosakaniza womwe umagwiritsidwa ntchito kwambiri ndi zigawo zitatu, womwe uli ndi zotsatira zoteteza za mitundu iwiri ya mpweya wosakaniza.MpweyaZimathandiza kuyaka, zimatha kuyeretsa madontho osungunuka, zimawonjezera ubwino wa weld ndi liwiro la weld; carbon dioxide imatha kupititsa patsogolo mphamvu ya weld komanso kukana dzimbiri, ndipo argon imatha kuchepetsa kufalikira kwa madzi. Pa weld ya carbon steel, low alloy alloy ndi chitsulo chosapanga dzimbiri, chisakanizo cha mpweya wa ternary ichi chili ndi mphamvu yabwino kwambiri yoteteza.

Argon+Helium+Carbon Dioxide

Heliumimatha kuwonjezera mphamvu ya kutentha, kusintha madzi osungunuka a dziwe ndikulimbikitsa mapangidwe a weld. Komabe, chifukwa helium ndi mpweya wopanda mphamvu, siikhudza kukhuthala ndi kuyaka kwa chitsulo chosungunula. Chifukwa chake, ingagwiritsidwe ntchito powotcherera chitsulo cha carbon ndi chitsulo chotsika cha pulse jet arc, chitsulo champhamvu kwambiri, makamaka kuwotcherera kwa short-circuit transition, ndi chitsulo chosapanga dzimbiri chopanda chitsulo chosasunthika cha all-position posintha magawo osiyanasiyana.
