Kuwotcherera, komwe kumadziwikanso kuti welding spatter kapena weld splatter, ndizochitika zofala panthawi yowotcherera pamakina owotcherera ma nati. Zimatanthawuza kutulutsa zitsulo zosungunuka zomwe zingasokoneze khalidwe la weld ndi madera ozungulira. Nkhaniyi ikufuna kupereka chithunzithunzi chakuthirira m'makina owotcherera nati, zomwe zimayambitsa, ndi njira zomwe zingathetsere kuchepetsa zotsatira zake.
- Zomwe Zimayambitsa Kumwaza: Pali zinthu zingapo zomwe zingapangitse kuti zisawonongeke panthawi yowotcherera mawanga. Kumvetsetsa zoyambitsa izi ndikofunikira kuti muzindikire ndikuthana ndi vutoli moyenera. Zina zomwe zimayambitsa ndi izi:
a. Pamalo oipitsidwa: Kukhalapo kwa dothi, mafuta, dzimbiri, kapena zonyansa zina pa nati kapena pamalo ogwirira ntchito zimatha kuyambitsa kuwaza.
b. Kuyika kolakwika kwa ma elekitirodi: Kusagwirizana pakati pa electrode ndi nati / workpiece kungapangitse mapangidwe osasunthika a arc, zomwe zimapangitsa kuti zisawonongeke.
c. Kuthamanga kosakwanira kwa ma elekitirodi: Kusakwanira kwa ma elekitirodi kungayambitse kusalumikizana bwino kwa magetsi, zomwe zimapangitsa kuti ma arging ndi kuwaza.
d. Kuchulukirachulukira kapena mphamvu yamagetsi: Kudzaza gawo lowotcherera ndi magetsi ochulukirapo kapena magetsi kungayambitse kutentha kwambiri komanso kuthirira kochulukirapo.
- Njira Zochepetsera: Kuti muchepetse kapena kupewa kudontha pakawotcherera mtedza, lingalirani kutsatira njira izi:
a. Kukonzekera pamwamba: Onetsetsani kuti mtedza ndi zogwirira ntchito ndi zoyera, zopanda zowononga, komanso zotsuka bwino musanawotchedwe.
b. Kuyanjanitsa kwa ma elekitirodi: Onetsetsani kuti maelekitirodi akugwirizana bwino ndi nati/workpiece, kuonetsetsa kuti ma arc akhazikika komanso kuchepetsa kukwapula.
c. Kuthamanga koyenera kwa ma elekitirodi: Sinthani kuthamanga kwa ma elekitirodi molingana ndi zomwe akulimbikitsidwa kuti mukwaniritse kulumikizidwa koyenera kwa magetsi ndikuchepetsa kufalikira.
d. Makonda oyenerera apano ndi magetsi: Gwiritsani ntchito makonzedwe apano ndi ma voliyumu omwe akulimbikitsidwa pa nati ndi zida zogwirira ntchito kuti mupewe kutentha kwambiri ndi kuwaza.
e. Gwiritsirani ntchito zokutira zothana ndi spatter: Kupaka zokutira zothana ndi sipatter pa nati ndi malo ogwirira ntchito kungathandize kuchepetsa kumamatira kwa spatter ndikuchepetsa kuyeretsa pambuyo pa weld.
f. Kukonza zida nthawi zonse: Kukonza makina owotcherera ma nati, kuphatikiza kuyang'anira ma elekitirodi, kukonzanso, kapena kusinthanso, kuti muwonetsetse kuti ikugwira ntchito bwino ndikuchepetsa kuthirira.
Kuthira mafuta nthawi yowotcherera nati kumatha kusokoneza mtundu wa weld komanso madera ozungulira. Pomvetsetsa zomwe zimayambitsa kutayira ndikugwiritsa ntchito njira zoyenera zochepetsera, ogwiritsa ntchito amatha kuchepetsa mapangidwe a spatter ndikukwaniritsa ma welds apamwamba kwambiri. Ndikofunikira kusunga malo aukhondo, kuyanjanitsa koyenera kwa ma elekitirodi ndi kukakamiza, komanso makonzedwe abwino apano ndi magetsi kuti muchepetse kuthirira ndikuwongolera magwiridwe antchito onse. Kusamalira zida pafupipafupi komanso kutsatira njira zabwino ndizofunikira kuti ntchito yowotcherera ma nati ikhale yopambana.
