Medium-frequency direct current (MFDC) spot kuwotcherera ndi njira yofunika kuwotcherera yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana, monga zamagalimoto, zakuthambo, ndi kupanga.Kuwonetsetsa kuti ma welds abwino ndikofunikira kwambiri kuti zitsimikizire kukhulupirika kwadongosolo komanso moyo wautali wa chinthu chomaliza.M'nkhaniyi, tikambirana mfundo zazikuluzikulu zowunikira khalidwe la MFDC kuwotcherera malo.
1. Mayeso a Weld Seam:
Chimodzi mwazinthu zazikulu pakuwunika kwaukadaulo mu kuwotcherera kwa malo a MFDC ndikuwunika kwa msoko wa weld.Izi zimaphatikizapo kuwunika ma geometry, kukula kwake, ndi mawonekedwe onse a weld.Msoko wowotcherera bwino uyenera kukhala wofanana, wopanda zilema zowoneka ngati ming'alu kapena porosity, komanso kukhala ndi mbiri yofananira ya mikanda.Zolakwika zilizonse mumsoko wowotcherera zimatha kuyambitsa zofooka zamapangidwe komanso kuchepa kwa magwiridwe antchito.
2. Kuyesa Kwamphamvu kwa Weld:
Kuti muwonetsetse kukhulupirika kwamakina a weld, kuyesa mphamvu ndikofunikira.Njira zosiyanasiyana zingagwiritsidwe ntchito, monga kuyesa kwamphamvu kapena kuyesa bend, kuti muwone momwe weld amatha kupirira kupsinjika.Zotsatira za mayesowa ziyenera kukwaniritsa kapena kupitilira milingo yomwe yatchulidwa, monga momwe zimakhalira ndi polojekiti kapena zofunikira zamakampani.
3. Kusanthula kwa Magetsi:
MFDC kuwotcherera malo kumadalira kuwongolera moyenera magawo amagetsi, kuphatikiza apano, magetsi, ndi nthawi.Kuyang'anira ndi kusanthula magawowa ndikofunikira pakuwongolera khalidwe.Kupatuka pamtengo womwe watchulidwa kungayambitse kusagwirizana kwa weld.Chifukwa chake, kuyang'anira ndi kusanthula kosalekeza ndikofunikira kuti muwonetsetse kuti makina owotcherera akugwira ntchito moyenera.
4. Electrode Wear and Maintenance:
Mkhalidwe wa ma elekitirodi owotcherera ndi wofunikira kwambiri pamtundu wa ma welds amawanga.Kuwunika pafupipafupi ma elekitirodi kuti avale ndi kung'ambika ndikofunikira.Maelekitirodi owonongeka amatha kupangitsa kuti musagwirizane bwino, zomwe zimapangitsa kuti ma welds asagwirizane.Kusamalira moyenera ndikusintha maelekitirodi pakafunika kofunika kuti akhalebe abwino.
5. Malo Owotcherera ndi Chitetezo:
Kuyang'ana kwaubwino kuyeneranso kuganizira za malo owotcherera komanso njira zachitetezo.Malo ogwirira ntchito aukhondo komanso olowera mpweya wabwino ndi ofunikira kuti ma welds azikhala abwino.Kuphatikiza apo, kutsatira ma protocol achitetezo ndikofunikira kuti muteteze ogwira ntchito ndikuwonetsetsa kukhulupirika kwa njira yowotcherera.
6. Zolemba ndi Kusunga Zolemba:
Kusunga zolemba zonse za njira yowotcherera ndikofunikira pakuwongolera kwaubwino ndi kufufuza.Zolemba izi ziyenera kukhala ndi tsatanetsatane monga zowotcherera, zidziwitso za oyendetsa, zotsatira zoyendera, ndi zowongolera zilizonse zomwe zachitika.
Pomaliza, kuyang'ana kwamtundu wapakatikati-kawirikawiri mwachindunji malo kuwotcherera ndi njira zambiri.Kuwonetsetsa kuti ma welds ndi abwino kumaphatikizapo kuwunika ma weld seams, kuyezetsa mphamvu, kuyang'anira magawo amagetsi, kukonza ma elekitirodi, kusunga malo otetezedwa, komanso zolemba mosamala.Miyezo iyi palimodzi imathandizira kupanga ma welds apamwamba kwambiri omwe amakwaniritsa miyezo yamakampani ndi zomwe makasitomala amayembekeza.
