Kusankha ndi Kugwiritsa Ntchito Ndodo Yolimba Yowotcherera Pamwamba Pokonza

Pankhani yokonza ndi kukonza zida zamafakitale,Ndodo Yowotcherera Yokhala Pamwambaikuyimira chinthu chofunikira kwambiri chogwiritsidwa ntchito powonjezera moyo wa ntchito ya zida zamakina. Mosiyana ndi ndodo zolumikizira zomwe zimapangidwa kuti zigwirizane ndi zinthu, mtundu uwu wa ma electrode umapangidwa mwapadera kuti uike wosanjikiza wa aloyi wosawonongeka kapena wosagonjetsedwa ndi dzimbiri pamwamba pa chitsulo. Njirayi, yomwe imadziwika kuti pamwamba kapena hardfacing, ndi yofunika kwambiri pomanganso ziwalo zosweka ndikuteteza zida zatsopano kuti zisawonongeke msanga.

D256 (B-80) ndi chitsanzo chabwino cha Ndodo Yothira Pamwamba Yopangira Zosefera. Ndi electrode yoyambira yopangidwa kuti ipange chitsulo chothira pachitsulo cha manganese. Chosakaniza ichi chimadziwika chifukwa cha kuphatikiza kwake kwapadera kwa kulimba kwambiri komanso luso lapadera lolimbitsa ntchito. Poyamba, chitsulocho chimakhala chofewa komanso chofewa, koma chimalimba mwachangu chikasinthidwa ndi kuzizira, komwe kumachitika chikakhudzidwa kapena kukakamizidwa, zomwe zimapangitsa kuti chikhale cholimba kwambiri kuti chisawonongeke.

Ntchito yayikulu ya iziNdodo Yowotcherera Yokhala PamwambaIli mu kukonzanso ndi kuteteza zigawo zomwe zakhudzidwa kwambiri ndi kusweka pang'ono. Ndi yoyenera kwambiri kulumikiza pazigawo zopangidwa ndi chitsulo chofanana cha manganese, chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale omwe ali ndi mphamvu zambiri. Zigawo zomwe zimakonzedwa ndi ndodoyi zimaphatikizapo malo odulira njanji, nsagwada zophwanyira, ndi mano ophimbira m'migodi ndi zida zomangira.

Kugwiritsa ntchito bwino Ndodo Yothira Pamwambayi kumafuna kutsatira njira zinazake zothira kuti zitheke bwino. Chifukwa cha kuphimba kwake koyambira, nthawi zambiri imagwira ntchito pa gwero lamagetsi la Direct Current (DC) ndi electrode yolumikizidwa ku positive pole (DCEP). Kutenthetsa chitsulo choyambira nthawi zambiri sikuvomerezeka pazitsulo za manganese, ndipo kuwongolera kutentha kwa interpass ndikofunikira kwambiri kuti tipewe kutentha kwambiri, komwe kungasokoneze kulimba kwa chitsulo chosungidwa ndi zinthu zoyambira.

Kugwiritsa ntchito mwanzeru kwa katswiri wapaderaNdodo Yowotcherera Yokhala Pamwambamonga D256 (B-80) ndi njira yofunikira kwambiri pa kasamalidwe ka katundu wa mafakitale. Posankha elekitirodi yoyenera mtundu winawake wa kuwonongeka.—Pankhaniyi, zotsatirapo zoopsa—Magulu okonza zinthu amatha kumanganso bwino zinthu zofunika kwambiri, kuchepetsa nthawi yogwira ntchito, komanso kuchepetsa ndalama zogwirira ntchito kwa nthawi yayitali. Ndodo Yothira Ma Welding iyi imapereka njira yodalirika komanso yothandiza yowonjezerera kulimba kwa makina ogwira ntchito pansi pa mikhalidwe yovuta kwambiri.
