Kukhudzika Kwapano Pakutentha Kwa Makina Owotcherera a DC Spot Pakatikati

M'dziko laukadaulo wazowotcherera, kuwongolera moyenera magawo osiyanasiyana ndikofunikira kuti mukwaniritse ma welds apamwamba kwambiri. Chimodzi mwazinthu zofunika izi ndi chapano, chomwe chimagwira ntchito yofunika kwambiri pakuwotcha makina owotcherera apakati a DC. M'nkhaniyi, tiwona momwe makinawo amakhudzidwira ndi kutentha kwa makina awa.

Makina owotcherera apakati a DC amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa chakuchita bwino komanso kulondola. Makinawa amapanga ma weld amphamvu komanso olimba potulutsa kutentha pamalo omwewo. Njira yowotchera imadalira kwambiri zomwe zimaperekedwa ku ma elekitirodi owotcherera.

1. Kukula Kwamakono:

   Kukula kwa magetsi omwe akudutsa muzitsulo zowotcherera kumakhudza mwachindunji kuchuluka kwa kutentha komwe kumapangidwa. Mafunde apamwamba amatulutsa kutentha kwambiri, komwe kumakhala kopindulitsa powotchera zinthu zokhuthala. Komabe, kuchulukitsitsa kwamagetsi kumatha kuyambitsa kutentha kwambiri komanso kuwonongeka kwa zinthu zomwe zikuwotcherera.

2. Nthawi Yapano:

   Kutalika kwa nthawi yomwe ma electrode amawotcherera ndi ma electrode ndi chinthu china chofunikira. Kutalikirana kwamakono kumalola kutentha kwambiri kwa zipangizo, zomwe zingakhale zopindulitsa pakupeza zomangira zolimba. Mosiyana ndi zimenezi, nthawi zazifupi ndizoyenera kuteteza kutentha kwakukulu muzinthu zosalimba.

3. Pulse Current vs. Continuous Current:

   Makina ena owotcherera apakati a DC amagwiritsa ntchito pulse current, pomwe ena amagwiritsa ntchito mosalekeza. Pulse current imatha kuwongolera bwino kuchuluka kwa kutentha komwe kumagwiritsidwa ntchito ndikuchepetsa chiopsezo cha kutentha kwambiri. Komano mosalekeza, nthawi zambiri amasankhidwa kuti agwiritse ntchito zomwe zimafuna kuwotcherera mwachangu komanso kutentha kosasintha.

4. Current Waveform:

   Mawonekedwe a mawonekedwe amakono, monga masikweya kapena katatu, amathanso kukhudza kutentha. Mitundu yosiyana siyana imagawira kutentha mosiyanasiyana kudera la weld, kukhudza mtundu ndi mphamvu ya weld yomaliza.

5. Kuganizira zakuthupi:

   Mtundu ndi makulidwe a zida zowotcherera zimagwira ntchito yofunika kwambiri pakuzindikiritsa zoikamo zomwe zili mulingo woyenera. Zida zina zimafuna mafunde okwera kuti zitenthetse bwino, pomwe zina zimatha kuwonongeka ngati zitakhala ndi mafunde kwambiri.

6. Njira Zoziziritsira:

   Ndikofunikira kudziwa kuti ngakhale magetsi ndi ofunikira pakuwotha, njira zoziziritsira ndizofunikanso kuti tipewe kuwonongeka kapena kuwonongeka kwa zinthu. Kuwongolera koyenera kwa machitidwe ozizira kumatsimikizira kuti weld imalimba bwino.

Pomaliza, kukhudza kwapano pakuwotcha kwa makina owotcherera apakati a DC sikungatsutsidwe. Poyang'anira mosamala kukula kwaposachedwa, nthawi, mawonekedwe a mafunde, ndikuganiziranso zida zomwe zimawotcherera, opanga ndi owotcherera amatha kupeza ma welds olondola, apamwamba kwambiri. Kumvetsetsa izi ndi kuyanjana kwawo ndikofunikira kuti muwongolere njira zowotcherera pamagwiritsidwe osiyanasiyana ndi mafakitale.
