Zomwe Zimayambitsa Kusweka mu Mid-Frequency Spot Welding?

Kuwotcherera mawanga apakati pafupipafupi ndi njira yowotcherera yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, koma imatha kukumana ndi zovuta monga kung'ambika m'malo olumikizirana. Kumvetsetsa zomwe zimayambitsa ming'aluyi ndikofunika kuti mukhale ndi khalidwe labwino komanso lodalirika la zigawo zowotcherera. M'nkhaniyi, tiwona zifukwa zomwe zimachititsa kuti pakhale kuwotcherera kwapakati pafupipafupi ndikukambirana njira zothetsera mavutowa.

1. Kusankha Zinthu: Nthawi zambiri, ming'alu imatha chifukwa cha kusankha kwa zinthu zomwe zimawotchedwa. Pamene zitsulo zosiyana kapena zipangizo zomwe zimakhala ndi kusiyana kwakukulu kwa ma coefficients owonjezera kutentha zimawotchedwa palimodzi, cholumikizira chowotcherera chimatha kusweka pakuzizira. Kuti tithane ndi vutoli, ndikofunikira kusankha zinthu zomwe zimagwirizana ndi kapangidwe kake komanso kutentha.
2. Zowotcherera Parameters: Zosagwirizana kapena zolakwika zowotcherera, monga kuwotcherera pano, nthawi yowotcherera, ndi mphamvu ya electrode, zimatha kuyambitsa ming'alu. Pamene magawowo sanakhazikitsidwe bwino, kulowetsedwa kwa kutentha ndi kugawa kungakhale kosagwirizana, kumayambitsa kupsinjika maganizo komwe kumalimbikitsa kusweka. Kusamalira nthawi zonse ndi kuwongolera zida zowotcherera kungathandize kukhalabe ndi magawo oyenera.
3. Kukonzekera Kolakwika Kophatikizana: Ubwino wa kukonzekera kophatikizana umathandizira kwambiri kupewa ming'alu. Kusayeretsedwa kokwanira ndi kuphatikizana kophatikizana kumatha kutsekereza zonyansa kapena kupanga mipata m'malo owotcherera, zomwe zimapangitsa ming'alu. Kukonzekera bwino pamodzi, kuphatikizapo kuyeretsa ndi kugwirizanitsa bwino, n'kofunika kwambiri kuti zitsulo zikhale bwino.
4. Residual Stress: Kuwotcherera kumabweretsa kupsinjika kotsalira muzinthu, zomwe zimatha kusokoneza pakapita nthawi. Chithandizo cha kutentha pambuyo pa weld kapena kuchepetsa nkhawa kungakhale kofunikira kuti muchepetse zovuta zotsalirazi ndikuwonjezera kukhulupirika kwa weld.
5. Kuchuluka kwa Hydrogen: Hydrogen yomwe idayambitsidwa panthawi yowotcherera imatha kulowa muzitsulo ndikupangitsa kuti zisawonongeke. Pofuna kuthana ndi izi, kuyanika bwino kwa maelekitirodi ndi kusungidwa koyenera kwa zipangizo pamalo owuma kungathandize kupewa kutsekemera kwa hydrogen.
6. Kuwongolera Kwabwino: Njira zosakwanira zoyendetsera bwino panthawi yowotcherera zimatha kuyambitsa zolakwika zosazindikirika zomwe pambuyo pake zimabweretsa ming'alu. Kuwunika pafupipafupi, kuyezetsa kosawononga, ndi njira zotsimikizira kuti zili bwino ndizofunikira kuti tizindikire ndikuthana ndi zovuta zomwe zingachitike msanga.
7. Welding Technique: Njira yowotcherera yokha imathanso kukhudza mwayi wosweka. Kuyika koyenera kwa ma elekitirodi, kutsatizana kowotcherera, ndi kuwongolera kutentha ndikofunikira kuti mukwaniritse chowotcherera chapamwamba kwambiri chomwe sichimakonda kusweka.

Pomaliza, kumvetsetsa zomwe zimapangitsa kuti pakhale kuwotcherera kwapakati pafupipafupi ndikofunikira kuti tipewe nkhaniyi ndikuwonetsetsa kudalirika kwa zida zowotcherera. Kusankha zinthu mosamala, zowotcherera zolondola, kukonzekera pamodzi koyenera, kuwongolera kupsinjika, komanso kuwongolera khalidwe lakhama ndi zinthu zofunika kwambiri pakukwaniritsa ma weld opanda ming'alu. Pothana ndi izi, opanga amatha kupanga ma welds omwe amakwaniritsa miyezo yapamwamba kwambiri komanso yolimba.
