Kuwotcherera matako ndi njira wamba yowotcherera yomwe imaphatikizapo kutenthetsa malekezero kapena m'mphepete mwa zida ziwiri zogwirira ntchito (nthawi zambiri zitsulo) kuti zisungunuke ndikuziphatikiza pamodzi ndikukakamiza.Poyerekeza ndi njira zina zowotcherera, kuwotcherera matako nthawi zambiri kumagwiritsa ntchito kukakamiza kupanga kulumikizana, pomwe kutentha kumafewetsa zinthuzo kuti zipangitse kulumikizana kolimba pansi pamavuto.
Njira yowotcherera matako imaphatikizapo kuwongolera kutentha, nthawi ndi kukakamiza kuonetsetsa kuti weld ikukwaniritsa miyezo yoyenera.Njira yowotcherera iyi imagwiritsidwa ntchito polumikizira komwe kumafunikira mphamvu komanso kulimba kwambiri, monga kupanga magalimoto, mapaipi, ndege, ndi madera ena ogulitsa.
Kuwotcherera matako kumatanthauza njira yowotcherera yopangidwa ndi matako.Malumikizidwe awa akhoza kukhala ndege kupita ku ndege, m'mphepete mpaka m'mphepete, kapena kulumikizana ndi mapaipi.Ma weld a matako nthawi zambiri amakhala amphamvu ndipo amatha kupirira akatundu akulu ndi zovuta.
Inflange or mankhwala chitoliro koyenera, kulumikiza matako kuwotcherera ndi njira wamba yolumikizira.Mwachitsanzo, mu kachitidwe ka mapaipi, kulumikiza kwa matako-kuwotcherera kwa flange ndiko kumangirira flange molunjika kumapeto kwa chitoliro kuti apange kulumikizana kolimba.Kulumikizana kwamtunduwu kumagwiritsidwa ntchito nthawi zambiri pamapulogalamu omwe amafunikira kulimba komanso kulimba kwamapangidwe, monga makina opangira mankhwala, mafuta ndi gasi.
Momwe malumikizidwe owotcherera matako amapangidwira ndikugwiritsidwa ntchito muzopanga zopanga ndi mapaipi.
1. matako kuwotcherera flange kugwirizana
Matako kuwotcherera flange amatanthauza kulumikiza flange kumapeto kwa chitoliro kapena malo athyathyathya a zida kudzera munjira yowotcherera matako.Kulumikizana kwamtunduwu kumagwiritsidwa ntchito kwambiri pamapulogalamu omwe amafunikira kusindikiza kwakukulu komanso mphamvu.Zotsatirazi ndizomwe zili zazikulu zamalumikizidwe a butt-welding flange:
Masitepe olumikiza: Lumikizani malo athyathyathya a chowotcherera matako ndi malo athyathyathya a kumapeto kwa chitoliro kapena zida, ndiyeno wotchera matako.Kawirikawiri, izi zimaphatikizapo kukakamiza koyenera pakati pa flange ndi chitoliro ndi kugwiritsa ntchito gwero la kutentha, monga kuwotcherera kwa arc, kusungunula malo ogwirizanitsa a flange ndi chitoliro kuti apange mgwirizano wamphamvu.
Minda yogwiritsira ntchito: Ma flanges owotcherera matako amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, mafuta, zoyendera gasi zachilengedwe ndi madera ena, makamaka m'malo omwe kutayikira kumayenera kupewedwa, monga makina amapaipi othamanga kwambiri.
Kusindikiza: Zolumikizira zowotcherera m'matako nthawi zambiri zimakhala zosindikizidwa bwino ndipo ndizoyenera nthawi zina zomwe zimafunikira pakutayikira kwapakatikati.
2. Mgwirizano wowotcherera matako
Kuwotcherera matako chitoliro kugwirizana ndi kulumikiza zigawo ziwiri za chitoliro pamodzi kudzera matako kuwotcherera ndondomeko.Kulumikizana kwamtunduwu nthawi zambiri kumagwiritsidwa ntchito popanga mapaipi.Zotsatirazi ndizo zikuluzikulu za kulumikiza mapaipi opangidwa ndi matako:
Njira zolumikizira: Lumikizani malekezero a zigawo ziwiri za chitoliro kudzera mu kuwotcherera matako.Kawirikawiri, izi zimaphatikizapo kugwirizanitsa malekezero a chitoliro, kutentha ndi kusungunula malo olumikizana ndi chitoliro, ndiyeno kupanga kugwirizanako pogwiritsa ntchito kukakamiza koyenera.
Malo ogwiritsira ntchito: Kulumikiza mapaipi opangidwa ndi matako kumagwiritsidwa ntchito kwambiri pomanga, kupanga mafakitale ndi kayendedwe ka mapaipi.
Mphamvu ndi Kusindikiza: Kulumikizana kwa mapaipi a matako kungapereke mphamvu zambiri ndipo, ngati kuchitidwa molondola, kusindikiza bwino.
