Kachulukidwe kakali pano ndi lingaliro lofunikira kwambiri pamakina owotcherera matako. Zimagwira ntchito yofunika kwambiri pozindikira momwe ntchito yowotcherera imagwirira ntchito komanso mtundu wake. Nkhaniyi ikufuna kufotokoza tanthauzo la kachulukidwe kakachulukidwe ka makina owotcherera matako, mawerengedwe ake, komanso momwe zimakhudzira mawonekedwe a weld.
- Tanthauzo la Kachulukidwe Kakanthawi: Kachulukidwe kakali pano amatanthauza kuchuluka kwa magetsi omwe akuyenda kudzera pagawo lopatsirana la chogwirira ntchito panthawi yowotcherera. Nthawi zambiri amayezedwa mu amperes pa square millimeter (A/mm²). Kumvetsetsa ndikuwongolera kachulukidwe kakali pano ndikofunikira kuti mukwaniritse zotsatira zabwino kwambiri.
- Kuwerengera Kachulukidwe Kakanthawi: Kuti muwerenge kachulukidwe kakali pano, gawani zowotcherera pano (mu ma amperes) ndi gawo la gawo lazogwirira ntchito (m'mamilimita apakati) pomwe mukuwotcherera. Kuwerengera uku kumapereka kuchuluka kwa kachulukidwe kameneka, komwe ndi kofunikira kwambiri komwe kumakhudza mphamvu ya weld, kuya kwake, ndi malo omwe amakhudzidwa ndi kutentha.
- Zotsatira pa Makhalidwe a Weld: Kuchulukana komweku kumakhudza kwambiri zotsatira za kuwotcherera. Kuchulukirachulukira kwapano kumatha kupangitsa kulowa mozama, kuthamanga kwa kuwotcherera mwachangu, ndikuwonjezera kutentha. Komabe, kuchulukirachulukira kwapano kungayambitse kulowa mopitilira muyeso, kupotoza, ndi zolakwika zomwe zingachitike mu weld joint.
- Kukulitsa Kuchulukana Kwamakono: Kusunga kachulukidwe koyenera ndikofunikira kuti mupeze ma weld apamwamba kwambiri. Ogwiritsa ntchito kuwotcherera ayenera kuganizira zinthu zosiyanasiyana, monga mtundu wa zinthu, makulidwe, ndi masinthidwe olumikizana, kuti akwaniritse kachulukidwe kameneka. Posintha mphamvu yowotcherera pano ndi ma elekitirodi, ma welder amatha kusinthira kachulukidwe kakanthawi kuti akwaniritse zomwe akufuna.
- Kuwongolera Kutentha ndi Kuchita Bwino: Kuwongolera kachulukidwe kakali pano ndikofunikira pakuwongolera kutentha kwapanthawi yowotcherera. Kuthamanga kwamakono koyendetsedwa bwino kumatsimikizira kuti kutentha koyenera kumagwiritsidwa ntchito kuti apange weld wamphamvu ndi yunifolomu popanda kuchititsa kutenthedwa kapena kutentha kwa workpiece.
- Mphamvu pa Weld Strength: Kachulukidwe kakali pano amatenga gawo lofunikira pakuzindikira mphamvu ndi kukhulupirika kwa weld. Kuchulukana koyenera kwapano kumatsimikizira kuphatikizika koyenera ndi kulumikizana kwazitsulo pakati pa zitsulo zoyambira, zomwe zimapangitsa kuti pakhale cholumikizira chodalirika komanso cholimba.
Pomaliza, kachulukidwe kameneka ndi gawo lofunikira kwambiri pamakina owotcherera matako omwe amakhudza mwachindunji momwe amawotcherera. Kumvetsetsa lingaliro la kachulukidwe kakali pano komanso chikoka chake pamawonekedwe a weld kumathandizira ogwiritsa ntchito kuwotcherera kuti apange zisankho zodziwika bwino ndikupeza zotsatira zabwino kwambiri zowotcherera. Poyang'anira mosamala kachulukidwe kakali pano, owotcherera amatha kupanga ma welds apamwamba kwambiri omwe amakwaniritsa zofunikira pakugwiritsa ntchito ndi mafakitale osiyanasiyana.
