Zomwe Zimayambitsa Electrode Sticking Phenomenon mu Medium-Frequency Inverter Spot Welding of Galvanized Steel Sheets?

Zitsulo zachitsulo zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kukana kwawo kwa dzimbiri. Komabe, pamene kuwotcherera zitsulo kanasonkhezereka ntchito sing'anga-pafupipafupi inverter malo kuwotcherera makina, chodabwitsa chodziwika kuti elekitirodi kumamatira akhoza kuchitika. Nkhaniyi ikufuna kufufuza zomwe zimayambitsa ma elekitirodi kumamatira mu sing'anga-kawirikawiri inverter malo kuwotcherera mapepala kanasonkhezereka zitsulo ndi kupereka zidziwitso mmene kuchepetsa nkhaniyi.

1. Zinc Nthunzi ndi Kuipitsidwa: Chimodzi mwa zifukwa zazikulu zomwe ma elekitirodi amamatira powotcherera mapepala achitsulo ndi kutulutsa mpweya wa zinki panthawi yowotcherera. Kutentha kwambiri kwaiye pa kuwotcherera akhoza vaporize nthaka ❖ kuyanika, amene condens ndi kumamatira ndi elekitirodi pamalo. Kuipitsidwa kwa zinkiku kumapanga wosanjikiza womwe umapangitsa kuti ma elekitirodi amamatire ku chogwirira ntchito, zomwe zimapangitsa kuti pakhale zovuta pakulekanitsa ma elekitirodi.
2. Mapangidwe a Zinc Oxide: Pamene mpweya wa zinc womwe umatulutsidwa panthawi yowotcherera umagwirizana ndi mpweya wa mumlengalenga, umapanga zinc oxide. Kukhalapo kwa zinc oxide pamalo opangira ma elekitirodi kumakulitsa nkhani yomamatira. Zinc oxide imakhala ndi zomatira, zomwe zimathandizira kumamatira pakati pa elekitirodi ndi pepala lachitsulo.
3. Zinthu za Electrode ndi zokutira: Kusankha kwa zinthu za elekitirodi ndi zokutira kumatha kukhudzanso kupezeka kwa ma elekitirodi. Zida zina zama elekitirodi kapena zokutira zitha kukhala zolumikizana kwambiri ndi zinki, zomwe zimawonjezera mwayi womamatira. Mwachitsanzo, maelekitirodi okhala ndi mkuwa amatha kumamatira chifukwa cha kuphatikizika kwawo kwa zinc.
4. Kuzirala kosakwanira kwa Electrode: Kuzizira kokwanira kwa ma elekitirodi kumatha kupangitsa kuti ma elekitirodi amamatire. Zowotcherera zimatulutsa kutentha kwakukulu, ndipo popanda njira zoziziritsira bwino, ma elekitirodi amatha kutentha kwambiri. Kutentha kokwezeka kumalimbikitsa kumamatira kwa nthunzi ya zinc ndi zinc oxide pamalo a elekitirodi, zomwe zimapangitsa kumamatira.

Njira Zochepetsera: Kuchepetsa kapena kupewa ma elekitirodi kumamatira mukamawotcherera mapepala achitsulo okhala ndi makina owotcherera apakati-frequency inverter spot, njira zingapo zitha kugwiritsidwa ntchito:

1. Kuvala kwa Electrode: Kuvala ma elekitirodi nthawi zonse ndikofunikira kuti muchotse zinki ndikusunga ma elekitirodi oyera. Kusamalira moyenera ma elekitirodi kumathandiza kupewa kudzikundikira kwa nthaka nthunzi ndi zinc oxide, kuchepetsa kupezeka kwa kumamatira.
2. Electrode Coating Selection: Kusankha zokutira za elekitirodi zomwe zili ndi kuyanjana kochepa kwa zinki kungathandize kuchepetsa kumamatira. Zovala zokhala ndi zotsutsana ndi ndodo kapena zokutira zomwe zimapangidwa makamaka kuti ziwotcherera zitsulo zamalata zitha kuganiziridwa.
3. Kuziziritsa Kokwanira: Kuonetsetsa kuti ma elekitirodi akuziziritsa mokwanira panthawi yowotcherera ndikofunikira. Njira zoziziritsira bwino, monga kuziziritsa madzi, zimatha kuchotsa kutentha ndikuletsa kutentha kwambiri kwa ma elekitirodi, kuchepetsa mwayi womamatira.
4. Kukhathamiritsa kwa Zowotcherera Parameters: Kuwongolera bwino magawo azowotcherera, monga apano, nthawi yowotcherera, ndi mphamvu ya electrode, kungathandize kuchepetsa kumamatira. Mwa kupeza zoikamo mulingo woyenera kwambiri parameter, ndondomeko kuwotcherera akhoza wokometsedwa kuchepetsa zinki vaporization ndi kukakamira.

Kupezeka kwa ma elekitirodi kumamatira mu sing'anga-kawirikawiri inverter malo kuwotcherera ma sheet kanasonkhezereka makamaka chifukwa cha kutulutsa nthaka nthunzi, mapangidwe zinki okusayidi, ma elekitirodi zinthu ndi ❖ kuyanika zinthu, ndi kusakwanira electrode kuzirala. Pogwiritsa ntchito njira monga kuvala ma elekitirodi nthawi zonse, kusankha zokutira zoyenera ma elekitirodi, kuonetsetsa kuti kuziziritsa kokwanira, ndi kukhathamiritsa magawo awotcherera, vuto lomamatira litha kuchepetsedwa. Njirazi zithandizira kuti ntchito zowotcherera zisamayende bwino, zokolola bwino, komanso ma welds apamwamba kwambiri mukamagwira ntchito ndi zitsulo zamalata.
