Mapangidwe a Surface Burns mu Nut Spot Welding: Zoyambitsa ndi Zochita?

Kuwotcha pamwamba, komwe kumadziwikanso kuti zipsera kapena kuwonongeka kwa pamwamba, kumatha kuchitika panthawi yowotcherera madontho a mtedza.Zowotcha izi ndi zolakwika zomwe zimakhudza mawonekedwe ndi kukhulupirika kwa olowa.Nkhaniyi ikufuna kufufuza momwe mawotchi amawotchera pamwamba pa nati, kukambirana zomwe zimayambitsa komanso zomwe zimapangitsa kuti zichitike.

1. Kulowetsa Kutentha Kwambiri: Chimodzi mwazinthu zomwe zimayambitsa kuwotcherera kwa nati ndikuyika kutentha kwambiri.Pamene zowotcherera, monga zamakono kapena nthawi, zimayikidwa kwambiri, kutentha kwakukulu kumapangidwa.Kutentha kochulukirapo kumeneku kungayambitse kuyaka kapena kuyaka kwa pamwamba pa mtedza kapena chogwirira ntchito, zomwe zimapangitsa kupanga zipsera.
2. Kuzizira Kosakwanira: Kuzizira kosakwanira kungathandizenso kupanga zilonda zam'mwamba.Panthawi yowotcherera, kuziziritsa koyenera ndikofunikira kuti muchepetse kutentha komwe kumapangidwa ndikuletsa kutentha kwambiri kwamadera ozungulira.Kuzizira kosakwanira, monga kusayenda bwino kwa madzi muzozizira kapena kukhudzana kosayenera ndi ma elekitirodi, kungayambitse kutenthedwa kwapadera ndi kuyaka pambuyo pake.
3. Kusankhidwa Kwa Electrode Molakwika: Kusankhidwa kwa ma elekitirodi kumagwira ntchito yofunika kwambiri popewa kuyaka kwa pamwamba.Ngati ma elekitirodi sali oyenera kuphatikizika kwa nati ndi workpiece, zitha kukhala ndi kuthekera kosautsa kutentha kapena kusakwanira kuziziritsa.Izi zingayambitse kutenthedwa kwapadera komanso kupanga zipsera pamtunda.
4. Kuipitsidwa: Kuipitsidwa pamwamba pa mtedza kapena workpiece kungathandize kupanga mapangidwe amoto.Mafuta, girisi, kapena zinthu zina zakunja zomwe zimapezeka pamwamba zimatha kuyatsa kapena kupanga utsi wochulukirapo zikakumana ndi kutentha kwambiri panthawi yowotcherera.Izi zingayambitse zizindikiro zowotcha pamtunda.
5. Kupanikizika Kosagwirizana: Kupanikizika kosagwirizana komwe kumachitika panthawi yowotcherera kungathandizenso kupanga mapangidwe amoto.Ngati kupanikizika kuli kwakukulu kapena kugawidwa mosagwirizana, kungayambitse kutenthedwa kwapadera ndi kutentha kwa zigawo za pamwamba.Kuwongolera kukakamiza koyenera komanso kugwiritsa ntchito mphamvu zofanana ndikofunikira kuti tipewe kuwonongeka kwapamtunda.

Kupewa ndi Kuchepetsa: Kuti muchepetse kupsa kwa pamwamba pa kuwotcherera ma nati, njira zingapo zitha kuchitidwa:

• Konzani zowotcherera, monga zapano, nthawi, ndi kukakamiza, kuti zitsimikizire kuti zili mkati mwazomwe zikuyenera kuphatikizidwira nati ndi chogwirira ntchito.
• Onetsetsani kuziziritsa koyenera posunga madzi okwanira komanso kuwongolera njira zoziziritsira ma elekitirodi.
• Sankhani maelekitirodi oyenerera okhala ndi zinthu zabwino zosinthira kutentha ndikuwona kuyanjana kwawo ndi mtedza ndi zida zogwirira ntchito.
• Yeretsani ndi kukonza malo a nati ndi workpiece kuti muchotse zodetsa zilizonse kapena zinthu zakunja musanayambe kuwotcherera.
• Gwiritsani ntchito kukakamiza kosasinthasintha komanso kofanana panthawi yowotcherera.

Kuwotchedwa kwa pamwamba pa kuwotcherera nati ndi zolakwika zomwe zimatha kusokoneza mawonekedwe ndi kusakhazikika kwa olowa.Kumvetsetsa zomwe zimayambitsa ndi zomwe zimapangitsa kuti apangidwe kumathandizira kuti azitha kuchitapo kanthu kuti apewe kapena kuchepetsa zochitika zawo.Mwa kukhathamiritsa zinthu zowotcherera, kuonetsetsa kuti kuziziritsa koyenera, kusankha ma elekitirodi oyenerera, kusunga ukhondo wa pamwamba, ndi kukakamiza mosasinthasintha, zowotcherera zimatha kuchepetsa chiwopsezo cha kuyaka pamwamba ndikukwaniritsa ma welds apamwamba a mtedza.
