Kodi Thermal Equilibrium Imaganiziridwa mu Medium-Frequency Direct Current Spot Welding?

M'dziko la kuwotcherera, pali zinthu zambiri zomwe zimagwira ntchito kuti zitsimikizire mtundu ndi kukhulupirika kwa chinthu chomaliza. Chimodzi mwazinthu zotere ndikuganizira za kutentha kwapakati mu mawotchi apakati pafupipafupi. M'nkhaniyi, tikufufuza kufunikira kwa kufanana kwa kutentha mu ndondomekoyi yowotcherera ndi zotsatira zake pa weld yomaliza.

kuwotcherera mawanga apakati pafupipafupi, komwe nthawi zambiri kumadziwika kuti MFDC kuwotcherera, ndi njira yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza zamagalimoto, zakuthambo, ndi kupanga. Zimaphatikizapo kujowina zidutswa ziwiri zachitsulo pogwiritsa ntchito mphamvu yamagetsi pamafupipafupi, nthawi zambiri pakati pa 1000 Hz ndi 10000 Hz, kupyolera mu maelekitirodi a alloy copper. Mphamvu yamagetsi imatulutsa kutentha, komwe kumasungunula chitsulo pamalo owotcherera, ndipo pozizira, weld yolimba imapangidwa.

Chinthu chimodzi chofunika kwambiri pakuchita izi ndikukwaniritsa kutentha kwapakati. Thermal equilibrium imatanthawuza momwe kutentha kumalowera kumalo ogwirira ntchito kumayenderana ndi kutayika kwa kutentha, zomwe zimapangitsa kutentha kokhazikika komanso koyendetsedwa mkati mwa zone yowotcherera. Kupeza kufanana kwamafuta ndikofunikira pazifukwa zingapo:

1. Kusasinthasintha ndi Ubwino: Kuwotchera pa kutentha kokhazikika kumatsimikizira kuti welds wokhazikika komanso wapamwamba kwambiri. Kutentha kosagwirizana kungayambitse zilema monga porosity, kusweka, kapena kulowa kosakwanira.
2. Mulingo woyenera Weld Properties: Zida zosiyanasiyana zimafuna kutentha kwapadera kuti mukwaniritse zomwe mukufuna. Thermal equilibrium imalola kuwongolera molondola kwa kutentha, kuonetsetsa kuti weld yomaliza imakhala ndi mphamvu yofunikira komanso yokhazikika.
3. Kupotoza Kochepa: Kuwotcherera kungapangitse kusokonezeka kwa chogwirira ntchito chifukwa cha kutentha ndi kuzizira kosiyana. Kutentha kwamafuta kumathandiza kuchepetsa kupotoza, kuonetsetsa kuti chomaliza chimasunga mawonekedwe ake ndi kukula kwake.
4. Mphamvu Mwachangu: Kuwotchera pa kutentha koyenera kumachepetsa kugwiritsa ntchito mphamvu komanso kumachepetsa kuwononga zinthu. Njira zowotcherera zosagwira bwino zimatha kupangitsa kuti pakhale ndalama zambiri zamagetsi komanso kuwonongeka kwa zinthu.

Kukwaniritsa matenthedwe matenthedwe mu kuwotcherera malo kwa MFDC kumaphatikizapo kuwongolera mosamala magawo osiyanasiyana, kuphatikiza apano, magetsi, nthawi yowotcherera, ndi mphamvu ya elekitirodi. Njira zowunikira kutentha ndi njira zowunikira nthawi zambiri zimagwiritsidwa ntchito kuti pakhale kutentha kosasinthasintha panthawi yonseyi.

Mapangidwe a makina owotcherera amakhalanso ndi gawo lofunikira pakukwaniritsa kutentha. Njira zochepetsera kutentha kwabwino, kuziziritsa koyenera kwa ma electrode, ndi kuwongolera kolondola kwa magawo owotcherera ndikofunikira kuti pakhale kutentha kokhazikika komanso koyendetsedwa.

Pomaliza, matenthedwe amtundu wa matenthedwe ndikofunikira kwambiri pakuwotcherera mawanga apakati pafupipafupi. Zimakhudza mwachindunji ubwino, kusasinthasintha, ndi mphamvu ya ndondomeko yowotcherera. Akatswiri opanga kuwotcherera ndi oyendetsa ayenera kuyang'anitsitsa ndikuwongolera magawo osiyanasiyana kuti akwaniritse ndikusunga kutentha, kuwonetsetsa kuti weld yomaliza ikukwaniritsa zofunikira ndi zofunikira.
