Kusanthula Makhalidwe Abwino mu Magulu Owotcherera a Mid-Frequency Spot

Kuwotcherera kwapakati pafupipafupi ndi njira yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, monga magalimoto ndi kupanga, polumikizana ndi zitsulo.Kuwonetsetsa kuti zolumikizira zowotcherera izi ndizofunikira kwambiri kuti tisunge kukhulupirika ndi chitetezo.Nkhaniyi ifotokozanso za zinthu zomwe zimagwirizanitsidwa ndi zowotcherera zapakati pa pafupipafupi.

Nkhani Yabwino 1: Weld Porosity Weld porosity imatanthawuza kukhalapo kwa zing'onozing'ono kapena mabowo muzitsulo zowotcherera, zomwe zingathe kufooketsa kapangidwe kake ndikuchepetsa kukhulupirika konse kwa weld.Pali zinthu zingapo zomwe zingapangitse kuti weld porosity, kuphatikiza mpweya wotchinga wocheperako, zowotcherera zosayenera, kapena zitsulo zoyipitsidwa.Njira zoyendetsera bwino, monga kuyang'anira gasi ndi kukonza nthawi zonse zida zowotcherera, ndizofunikira kuti tithane ndi vutoli.

Nkhani Yabwino 2: Weld Cracking Weld cracking, kapena kupanga ming'alu mu cholumikizira chowotcherera, ndi vuto lina lodziwika bwino.Zitha kuchitika chifukwa cha kuzizira kofulumira kwa weld, kutentha kosakwanira, kapena kupsinjika kwakukulu kotsalira.Njira zodzitetezera monga kuwongolera kuziziritsa, kugwiritsa ntchito njira zoyenera zotenthetsera, ndi kugwiritsa ntchito zida zoyenera zodzazira zingathandize kuchepetsa kung'ambika kwa weld.

Nkhani Yabwino Yachitatu: Kulowa Kosakwanira Kulowa kosakwanira kumachitika pamene weld amalephera kufikira makulidwe azinthu zoyambira, zomwe zimapangitsa kuti mgwirizano ukhale wofooka.Zinthu zomwe zathandizira nkhaniyi ndi monga kuwotcherera molakwika, kukula kosayenera kwa ma elekitirodi, kapena kukonzekera pamodzi molakwika.Ogwira ntchito akuyenera kuphunzitsidwa mokwanira ndikuyang'ana zida zawo zowotcherera pafupipafupi kuti awonetsetse kuti zalowa moyenera komanso zolumikizana bwino.

Nkhani Yabwino 4: Weld Spatter Weld spatter ndi ejection ya zitsulo zosungunuka pa nthawi yowotcherera, zomwe zingayambitse ngozi za chitetezo ndi kuchepetsa kukongola.Kuvala koyenera kwa ma elekitirodi, kukhala ndi malo aukhondo ogwirira ntchito, komanso kusintha magawo owotcherera kungathandize kuchepetsa kupezeka kwa sipada ya weld.

Nkhani Yabwino 5: Kuvala kwa Electrode Mkhalidwe wa ma elekitirodi owotcherera umakhala ndi gawo lofunikira pakukwaniritsa ma weld apamwamba kwambiri.Kuvala kwa ma elekitirodi, komwe kumachitika chifukwa cha zinthu monga kuzizira kopitilira muyeso kapena kusakwanira, kumatha kupangitsa kuti mgwirizano ukhale wosagwirizana komanso kuchuluka kwa ndalama zokonzera.Kukhazikitsa ma electrode monitoring ndi ndandanda zosinthira kungathandize kuthana ndi vutoli.

Kutsiliza: Kuwonetsetsa kuti maulalo owotcherera apakati pafupipafupi ndikofunikira kuti zinthu zisungidwe komanso chitetezo m'mafakitale osiyanasiyana.Pothana ndi zovuta zomwe wamba monga weld porosity, ming'alu, kulowa kosakwanira, weld spatter, ndi ma elekitirodi kuvala, opanga amatha kukonza njira zawo zowotcherera ndikupanga zolumikizira zodalirika, zapamwamba kwambiri.Njira zowongolera zowongolera bwino, kuphunzitsidwa kwa oyendetsa, ndi kukonza zida pafupipafupi ndizofunikira kwambiri pakukwaniritsa ma welds okhazikika, apamwamba kwambiri.
