Zomwe Zimayambitsa Ming'alu Pazinthu Zowotchedwa ndi Makina Owotcherera a Nut Spot?

Spot kuwotcherera ndi njira yomwe imagwiritsidwa ntchito kwambiri popanga, yomwe imadziwika chifukwa chachangu komanso liwiro. Komabe, monga njira ina iliyonse yowotcherera, sizitetezedwa kuzinthu zina zomwe zingakhudze mtundu wa chinthu chomaliza. Vuto limodzi lomwe anthu ambiri amakumana nalo mukamagwiritsa ntchito makina owotcherera a nati ndi kukhalapo kwa ming'alu ya zinthu zowotcherera. M’nkhani ino, tiona zifukwa zimene zinayambitsa nkhaniyi.

1. Kupanikizika Kosakwanira:Chifukwa chimodzi chachikulu cha ming'alu ya zinthu zowotcherera ndi kupanikizika kosakwanira komwe kumagwiritsidwa ntchito panthawi yowotcherera. Kukakamiza sikukwanira, chitsulo chosungunula sichingagwirizane bwino, zomwe zimapangitsa kuti ziwalo zofooka zomwe zimakonda kusweka.
2. Zowotcherera Zolakwika:Chinthu chinanso chofunikira ndikugwiritsira ntchito zowotcherera zolakwika, monga zamakono, nthawi, kapena mphamvu ya electrode. Zosinthazi ziyenera kusanjidwa mosamala potengera zinthu zomwe zikuwotcherera, ndipo kupatuka kulikonse kuchokera pazikhazikiko zabwino kwambiri kungayambitse ming'alu.
3. Kusagwirizana Kwazinthu:Zida zomwe zikuwotchedwa ziyenera kugwirizana kuti zigwirizane ndi mgwirizano wamphamvu, wopanda ming'alu. Ngati zitsulo zosiyana kapena zipangizo zokhala ndi makulidwe osiyanasiyana zimawotchedwa, mwayi wa ming'alu umawonjezeka, pamene amayankha mosiyana ndi kuwotcherera.
4. Kuipitsidwa ndi Oxidation:Kuipitsidwa kulikonse komwe kumayenera kuwotcherera, monga dzimbiri, mafuta, kapena zonyansa zina, kumatha kusokoneza njira yowotcherera ndikupanga mawanga ofooka omwe amatha kusweka. Kuonjezera apo, okosijeni amatha kuchitika ngati zitsulo sizikutsukidwa bwino kapena kutetezedwa, zomwe zimapangitsa kuti subpar welds.
5. Kusamalira Molakwika Electrode:Electrodes ndi zinthu zofunika kwambiri pakuwotcherera mawanga. Ngati atatopa, kuwonongeka, kapena kusamalidwa bwino, angayambitse kusagwirizana kwa njira yowotcherera, zomwe zimapangitsa kuti pakhale ming'alu ya mankhwala omaliza.
6. Thermal Stress:Kutentha kofulumira ndi kuziziritsa panthawi yowotcherera kungayambitse kupsinjika kwa kutentha m'malo owotcherera. Ngati kupsinjika kumeneku sikuyendetsedwa bwino, kungayambitse kupanga ming'alu pakapita nthawi.
7. Kupanda Kukonzekera Kukonzekera Kuwotcherera:Kukonzekera koyenera, kuphatikizapo kugwirizanitsa zipangizo ndi kuonetsetsa kuti zakhazikika bwino, n'kofunika kwambiri kuti tipewe ming'alu panthawi yowotcherera. Kukonzekera kosakwanira kungayambitse kusokoneza kapena kupindika, kuchititsa kupanga ming'alu.

Pomaliza, ming'alu ya zinthu zowotcherera ndi makina owotcherera a nati imatha kukhala ndi zifukwa zosiyanasiyana, zomwe nthawi zambiri zimalumikizidwa ndi zovuta, zowotcherera, kuyanjana kwazinthu, kuipitsidwa, kukonza ma elekitirodi, kupsinjika kwamafuta, komanso kukonzekera kuwotcherera. Kuti apange ma welds apamwamba kwambiri, opanda ming'alu, ndikofunikira kusamala kwambiri zinthuzi ndikuwonetsetsa kuti kuwotcherera kumachitidwa molondola komanso kutsatira njira zabwino. Pothana ndi izi, opanga amatha kukulitsa kukhulupirika ndi kulimba kwa zinthu zawo zowotcherera.
