Adiabatic welding ndi njira yotchuka yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana komwe kumafunika kulumikiza zitsulo molondola komanso moyenera. Komabe, chimodzi mwazovuta zazikuluzikulu mu njirayi ndi kubadwa kwa kutentha kwakukulu, komwe kungakhudze kukhulupirika kwa mgwirizano wowotcherera. Kuti athetse vutoli, kuzizira kwachangu komanso kosavuta kwa adiabatic weld kwatulukira ngati njira yodalirika. M'nkhaniyi, tikambirana za mawonekedwe ndi ubwino wa njira yozizirayi ndikuwunika zinthu zomwe zimathandizira kukhazikitsidwa kwake.
Kuzizira kofulumira komanso kosavuta kwa adiabatic weld kumachepetsa kwambiri nthawi yoziziritsa yomwe ikufunika m'dera lotsekemera. Kutentha kwakukulu komwe kumapangidwa panthawi yowotcherera kumatayidwa mwachangu pogwiritsa ntchito luso lapadera loziziritsa, kuwonetsetsa kukhulupirika ndi mphamvu ya olowa. Njira yoziziritsira iyi imapereka maubwino angapo monga kuchuluka kwa zokolola, kuchepetsa kupotoza kwa pambuyo pa kuwotcherera, kuwongolera bwino kwa njira yowotcherera, komanso chitetezo chowonjezereka.
Chinthu chimodzi chomwe chimathandizira kuzirala mwachangu komanso kosavuta powotcherera adiabatic ndi Welding Insulated Gas Cylinders. Silindayo imatenga kamangidwe ka magawo awiri, omwe amapangidwa ndi thanki yamkati ndi thanki yakunja, ndipo imakhala ndi chotchingira kutentha. Pogwiritsa ntchito zida zotchinjiriza zamitundu yambiri kuti zikhalebe ndi vacuum yayikulu, imagwiritsidwa ntchito ponyamula ndi kusunga mpweya, nayitrogeni wamadzimadzi, argon wamadzimadzi ndi zakumwa zina.
Ma cylinders akuwotcherera amagasi amapezeka m'mitundu yosiyanasiyana kuti akwaniritse zofunikira zosiyanasiyana. Malingana ndi kupanikizika kwa valve yotetezera, imagawidwa kukhalapakati (MP) ndi kuthamanga (P). Kuphatikiza apo, pali kusiyanasiyana kwapamwamba kwambiri (VEP), komwe nthawi zambiri kumagwiritsidwa ntchito pokhudzana ndi kupsinjika kwapakati komanso kwakukulu. Assortment iyi imawonetsetsa kuti masilinda amatha kupereka bwino mpweya wamadzi ndi mpweya pazosowa zosiyanasiyana zowotcherera.
Pali zabwino zambiri zogwiritsira ntchito ma silinda a gasi otenthetsera. Kumanga kwake kwa zigawo ziwiri ndi kutsekemera kwa kutentha kumathandiza kusunga kutentha kwa mpweya wosungidwa, kuteteza kusintha kulikonse komwe kungakhudze njira yowotcherera. Mpweya wapamwamba womwe umasungidwa mkati mwa silinda umatsimikiziranso kuyera ndi kukhazikika kwamadzi osungidwa, zomwe zimapangitsa kuti ntchito zowotcherera zodalirika komanso zosagwirizana.
Kuphatikiza apo, kuzizira kofulumira komanso kosavuta komwe kumapezeka ndi mankhwalawa kumachepetsa kwambiri nthawi yopuma pakati pa ntchito zowotcherera. Ndi kutentha kwakukulu kumatayika mofulumira, ma welders amatha kupita kumalo otsatira, kuonjezera zokolola zonse. Nthawi yoziziritsa yochepetsedwa imachepetsanso kupotoza pambuyo pa weld kuti mupeze zotsatira zowotcherera. Kuonjezera apo, njira yoziziritsira iyi imachepetsa kutenthedwa kwa wowotchera ndi kutentha kwambiri, kuonjezera chitetezo cha welder.
Pomaliza, kuzizira kwachangu komanso kosavuta kwa adiabatic welds ndikofunikira kuti mukwaniritse ma welds apamwamba popanda kusokoneza kukhulupirika ndi mphamvu. Ma silinda a gasi opangidwa ndi welded ndi zinthu zomwe zimakwaniritsa njira yoziziritsa iyi pomanga zigawo ziwiri, kutchinjiriza kutentha, komanso kukonza vacuum yayikulu. Kutha kwake kusunga ndi kunyamula mpweya wamadzimadzi ndi mpweya kumapangitsa kuti ikhale yoyenera pamitundu yosiyanasiyana yowotcherera. Kugwiritsa ntchito njira zoziziritsa mwachangu komanso zosavuta sizimangowonjezera zokolola, komanso kumawonjezera zotsatira zowotcherera ndikuwonetsetsa chitetezo cha welder.
