Zomwe Zimayambitsa Mivuvu mu Kuwotcherera Nut Spot?

Mivuvu mkati mwa ma weld point mu kuwotcherera nut spot itha kukhala nkhani wamba yomwe imakhudza mtundu ndi kukhulupirika kwa weld. Ma thovu awa, omwe amadziwikanso kuti porosity, amatha kufooketsa weld ndikusokoneza magwiridwe ake. M'nkhaniyi, tiwona zifukwa zazikulu zomwe zimapangitsira thovu mu kuwotcherera madontho a mtedza ndikukambirana njira zothetsera vutoli.

1. Zowononga:Kukhalapo kwa zonyansa monga mafuta, dzimbiri, kapena zinthu zakunja zomwe zili pamalo omwe amawotcherera zimatha kuyambitsa thovu. Zoyipitsidwazi zimatha kusungunuka panthawi yowotcherera, zomwe zimapangitsa kuti pakhale ma voids mkati mwa weld.
2. Kukonzekera kwa Pamwamba Kosakwanira:Kusakwanira kuyeretsa kapena kukonza malo oti aziwotcherera kungapangitse kuti weld asamakhale bwino. Kuyeretsa koyenera ndi kuchotsa zigawo za oxide ndizofunikira kuti tipeze ma welds amphamvu komanso odalirika.
3. Gasi Wotsekeredwa mu Bowo Lopangidwa ndi Ulusi:Powotcherera mtedza, bowo lopangidwa ndi ulusi nthawi zina limatha kutsekera mpweya kapena mpweya. Gasi wotsekekawa amatulutsidwa panthawi yowotcherera ndipo amatha kupanga thovu mkati mwa weld point. Kuwonetsetsa kuti dzenje la ulusi ndi loyera komanso lopanda chotchinga chilichonse ndikofunikira.
4. Gasi Woteteza Wosakwanira:Mtundu ndi kuchuluka kwa kayendedwe ka gasi wotchingira zimathandizira kwambiri pakuwotcherera. Mpweya wosatetezedwa wotetezedwa ukhoza kulola kuti mpweya wa mumlengalenga ulowe m'dera la weld, zomwe zimatsogolera ku porosity.
5. Zowotcherera Parameters:Kugwiritsa ntchito njira zowotcherera zosayenera, monga kutentha kwambiri kapena kuwotcherera kwambiri, kungayambitse kupanga thovu. Izi zitha kupangitsa kuti chitsulo chiwotche komanso kuti chikhale nthunzi, zomwe zimapangitsa kuti pakhale porosity.

Zothetsera:

1. Kuyeretsa Mokwanira:Onetsetsani kuti malo oti aziwotcherera ayeretsedwa bwino komanso opanda zowononga. Izi zingaphatikizepo kugwiritsa ntchito zosungunulira, kupukuta waya, kapena njira zina zoyeretsera.
2. Gasi Woteteza Moyenera:Sankhani mpweya wotetezera woyenerera wa zinthu zomwe zikuwotchedwa ndikuonetsetsa kuti kayendetsedwe kake kasinthidwa moyenera kuti mukhale ndi chitetezo.
3. Zowotcherera Zokwanira:Sinthani magawo awotcherera kuti agwirizane ndi zinthu zenizeni komanso makulidwe omwe akuwotcherera. Izi zikuphatikizapo kuwotcherera panopa, voteji, ndi liwiro kuyenda.
4. Kutulutsa mpweya:Khazikitsani njira zolola gasi wotsekeredwa m'mabowo kuti atuluke musanawotchere, monga kutenthetsa kapena kuyeretsa.
5. Kusamalira Nthawi Zonse:Yang'anirani ndikuwongolera zida zowotcherera nthawi ndi nthawi kuti muwonetsetse kuti zikuyenda bwino komanso kuti palibe zotayikira kapena zovuta zomwe zingayambitse porosity.

Pomaliza, kukhalapo kwa thovu kapena kuwotcherera mtedza kumabwera chifukwa cha zinthu zosiyanasiyana, monga zowononga, kusakonzekera bwino kwa pamwamba, mpweya wotsekeka m'mabowo, mpweya wotchinga wocheperako, ndi zowotcherera zosayenera. Pothana ndi mavutowa poyeretsa bwino, gasi wotchinga bwino, zowotcherera zowotcherera bwino, kutulutsa mpweya, komanso kukonza nthawi zonse, mtundu wa weld ukhoza kusintha kwambiri, zomwe zimapangitsa kulumikizana mwamphamvu komanso kodalirika.
