Kodi Kupanikizika Kumasintha Bwanji Panthawi Yowotcherera Pakati pa Frequency Spot?

Kuwotcherera kwapakati pafupipafupi, komwe kumatchedwanso kuti kuwotcherera kwapakati pafupipafupi, ndi njira yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana polumikiza zida zachitsulo.Panthawi yowotcherera, magawo angapo amagwira ntchito yofunika kwambiri pozindikira mtundu wa weld.Chimodzi mwa magawowa ndi kukakamizidwa kogwiritsidwa ntchito, komwe kumakhudza kwambiri njira yowotcherera komanso mphamvu yolumikizana.M'nkhaniyi, tiwona momwe kupanikizika kumasinthira pakawotcherera mawanga apakati pafupipafupi komanso zotsatira zake pamtundu wa weld.

Kupanikizika ndi gawo lofunikira pakuwotcherera kwa malo, chifukwa kumakhudza kulumikizana pakati pa zida zogwirira ntchito ndi ma elekitirodi, zomwe zimakhudza kutulutsa kutentha ndi kutuluka kwa zinthu.Pakatikati pa mawotchi apakati pafupipafupi, kukakamiza komwe kumayikidwa pakati pa ma elekitirodi ndi zida zogwirira ntchito kumasintha nthawi yonse yowotcherera.

1. Kulumikizana Koyamba: Pamene ma elekitirodi akuyandikira workpieces, kuthamanga kumayamba kuwonjezeka.Kuthamanga koyambirira kumeneku kumatsimikizira kuyendetsa bwino kwa magetsi komanso kutentha koyenera pa mawonekedwe awotcherera.
2. Compression Phase: Ma electrode akalumikizana ndi zida zogwirira ntchito, kupanikizika kumapitilira kukwera pomwe ma electrode amapondereza zidazo.Gawo lopanikizanali ndilofunika kwambiri kuti pakhale malo olumikizirana ofanana ndikuchepetsa mipata ya mpweya yomwe ingakhudze mtundu wa weld.
3. Welding Current Application: Pamene kuwotcherera pakali pano kumagwiritsidwa ntchito, kukana pa mawonekedwe kumatulutsa kutentha, zomwe zimapangitsa kuti zinthu zisungunuke.Panthawi imeneyi, kupanikizika kumatha kutsika pang'ono chifukwa cha kufewetsa kwa zipangizo komanso kupanga nugget yosungunuka.
4. Gwirani Gawo: Pambuyo pa kuwotcherera pakali pano kuzimitsidwa, kupanikizika kumasungidwa kwa kanthawi kochepa panthawi yogwira.Gawoli limalola kuti zinthu zosungunula zikhazikike ndikupanga mgwirizano wamphamvu wa weld.Kupanikizika kumatsimikizira kuti kulimbitsa kumapezeka ndi kugwirizanitsa bwino, kuchepetsa kusokoneza.
5. Gawo Lozizira: Pamene cholumikizira chowotcherera chikuzizira, kupanikizika kumatha kutulutsidwa pang'onopang'ono.Komabe, mulingo wina wa kupanikizika ungagwiritsidwebe ntchito kuti ateteze kugwedezeka kulikonse kapena kupotoza komwe kumachitika chifukwa cha kuzizira kofulumira.

Kusiyanasiyana kwa kukakamizidwa panthawi yapakati pa nthawi yowotcherera malo kumakhudza mwachindunji ubwino wa weld ndi kukhulupirika.Kuwongolera moyenera kumathandizira pazifukwa izi:

1. Mapangidwe a Nugget: Kuthamanga koyenera kumatsimikizira kuti zinthu zosungunula zimagawidwa mofanana, kupanga nugget yamphamvu komanso yosagwirizana.Kupanikizika kosakwanira kungayambitse mapangidwe osagwirizana ndi nugget ndi ziwalo zofooka.
2. Kuchepetsa Porosity: Kuthamanga kokwanira kumathandiza kuchepetsa kukhalapo kwa matumba a mpweya ndi voids mkati mwa weld.Zolakwika izi zimatha kufooketsa mgwirizano ndikuchepetsa mphamvu yake yonyamula katundu.
3. Kuchepetsa Kupotoza: Kuwongolera kupanikizika panthawi yoziziritsa kumalepheretsa kugwedezeka kwachangu komanso kusokonezeka kwa zigawo zowotcherera.
4. Kupititsa patsogolo Magetsi ndi Thermal Conductivity: Kupanikizika koyenera kumawonjezera kulumikizana pakati pa ma elekitirodi ndi zida zogwirira ntchito, zomwe zimapangitsa kuti magetsi azikhala bwino komanso matenthedwe, zomwe zimapangitsa kuti kutentha kuzikhala bwino.

M'malo owotcherera mawanga apakati pafupipafupi, kusinthasintha kwamakasitomala kumagwira ntchito yofunika kwambiri pakuzindikira mtundu ndi kudalirika kwa ma weld joints.Kuyambira kukhudzana koyambirira mpaka kuzizira, kuwongolera kupanikizika kumatsimikizira kuyenda koyenera kwa zinthu, kupanga ma nugget, ndi kukhulupirika kolumikizana.Opanga ndi opangira kuwotcherera ayenera kuyang'anira mosamala ndikuwongolera magawo okakamiza kuti akwaniritse ma welds okhazikika komanso apamwamba kwambiri, zomwe zimathandizira kukhazikika kwadongosolo lazinthu zopangidwa.
