Maelekitirodi Omwe Amawotcherera a Chitsulo cha Arc ndi Manual a Nickel-Copper Alloys: Ni202

Ma Electrode a Chitsulo cha Arc a Manualndi zida zofunika kwambiri pakuwotcherera kwamakono, zomwe zimapereka kusinthasintha komanso kudalirika polumikiza zitsulo zosiyanasiyana. Electrode ya Ni202 ndi chitsanzo chabwino cha chinthu chotere, chomwe chapangidwira makamaka kuwotcherera ma aloyi a nickel-copper. Imagwirizana ndi miyezo ya GB/T EN4060 ndi AWS A5.11 ENiCu-7, kuonetsetsa kuti magwiridwe antchito ndi chitsimikizo chapadziko lonse lapansi. Electrode iyi imadziwika ndi kapangidwe ka waya wake wapakati wa Ni70Cu30, womwe umagwirizana ndi banja la aloyi a Monel, womwe umapereka kukana dzimbiri komanso mphamvu zabwino.

Electrode ya Ni202 ili ndi utoto wa titanium-calcium, womwe umathandizira kuti arc yake igwire bwino ntchito komanso kuti zitsulo zisamayende bwino. Chitsulo choyikamo chimakhala ndi manganese ndi niobium, zomwe zimapangitsa kuti chisamathe kusweka panthawi yowotcherera komanso pambuyo pake. Izi zimapangitsa kuti ikhale yoyenera kwambiri kugwiritsidwa ntchito komwe kupsinjika kwa kutentha ndi kusweka kwamphamvu kumakhudza. Kapangidwe ka mankhwala kamatsimikizira kuti makinawo ndi olimba komanso kulimba mu cholumikizira chowotcherera.

Ponena za magwiridwe antchito, iziManual Metal Arc Electrodeimagwira ntchito bwino kwambiri ndi mawonekedwe ake osavuta kugwiritsa ntchito. Imagwira ntchito bwino pamagetsi onse awiri a alternating current (AC) ndi direct current (DC), zomwe zimapangitsa kuti zinthu zisinthe m'malo osiyanasiyana amafakitale. Kuyatsa kwa arc kumakhala kosalala, ndipo njira yowotcherera imakhala ndi kutayikira kochepa komanso kuchotsa mosavuta slag. Zinthu zimenezi zimathandiza kuti mikanda yowotcherera ikhale yabwino kwambiri komanso yokongola, zomwe zimachepetsa kufunika komaliza kwambiri pambuyo pa weld.

Ntchito zazikulu za elekitirodi ya Ni202 zikuphatikizapo kuwotcherera zitsulo za nickel-copper ndi zitsulo zosiyana, komwe kumatsimikizira kuti malo olumikizirana olimba komanso osasweka ndi ming'alu ndi olimba. Imagwiritsidwanso ntchito ngati chophimba kapena chophimba kuti ipereke malo osapsa ndi dzimbiri pazitsulo zoyambira zomwe zili ndi malo owopsa. Makampani ambiri omwe amapindula ndi izi ndi monga kukonza mankhwala, uinjiniya wa m'madzi, ndi mafuta ndi gasi, komwe kudalirika kumakhala kofunika kwambiri pakakhala zovuta.

Ni202 ikuyimira njira yapamwamba kwambiri mkati mwa gulu laMa Electrode a Chitsulo cha Arc a Manual, kuphatikiza magwiridwe antchito abwino kwambiri a welding ndi mphamvu zachitsulo. Kutsatira kwake miyezo yapadziko lonse lapansi komanso kusinthasintha kwa welding ya AC ndi DC kumapangitsa kuti ikhale chisankho chodalirika kwa akatswiri omwe akufuna kudalirika komanso kuchita bwino ntchito zoweta za nickel-alloy.
