Ndodo ya A412: Yankho Labwino Kwambiri la Kuwotcherera Zitsulo Zosapanga Dzira

Ponena za kuwotcherera zitsulo zosapanga dzimbiri, kusankha ma electrode kumachita gawo lofunika kwambiri pakudziwa mtundu ndi kulimba kwa chowotchereracho. Pakati pa zosankha zambiri zomwe zilipo pamsika, A412ndodo zowotchereraNdi chinthu choyamba chomwe chimasankhidwa pakati pa akatswiri komanso anthu omwe amakonda kugwiritsa ntchito. A412 ndi electrode yachitsulo chosapanga dzimbiri ya Cr26Ni21Mo2 yokhala ndi calcium titanium coating yomwe imapereka magwiridwe antchito abwino komanso kusinthasintha kwa ntchito zosiyanasiyana zowotcherera.

Ma electrode a A412 opangidwa kuti apereke zotsatira zabwino kwambiri pogwira ntchito ndi chitsulo chosapanga dzimbiri, amapereka magwiridwe antchito abwino kwambiri pa AC ndi DC welding. Kapangidwe kake kapadera, kuphatikizapo kuwonjezera molybdenum ku chitsulo chosungidwa, kumawonjezera kukana kwake ku dzimbiri, mphamvu ya kutentha ndi ming'alu poyerekeza ndi njira zina zama electrode monga A402 ndi A407. Izi zimapangitsa A412 kukhala chisankho choyamba cha mapulojekiti owetera omwe amafunikira mphamvu komanso kulimba kwambiri.

Chimodzi mwa zabwino zazikulu za ma electrode a A412 ndi kuthekera kwawo kupereka zotsatira zodalirika komanso zogwirizana pa ntchito zosiyanasiyana zowotcherera. Kaya mukugwira ntchito pazinthu zomangira, makina kapena kupanga chitsulo chosapanga dzimbiri, ma electrode a A412 amapereka kulondola komanso kudalirika komwe mukufunikira pa ma weld apamwamba kwambiri. Chophimba cha titanium-calcium chimawonjezera kukhazikika kwa arc ndi kulekanitsidwa kwa slag, kuonetsetsa kuti ma weld osalala komanso oyera ndi ochepa.

A412ndodo zowotchereraamadziwika kuti ndi osavuta kugwiritsa ntchito komanso osinthasintha. Ma electrode awa angagwiritsidwe ntchito ndi makina onse awiri a AC ndi DC, zomwe zimapangitsa kuti olumikiza ma waya akhale osinthasintha komanso osavuta kugwiritsa ntchito m'malo osiyanasiyana. Kaya ndinu wolumikiza ma waya wodziwa bwino ntchito kapena wolumikiza watsopano, A412ndodo zowotchereraperekani chidziwitso chosavuta kugwiritsa ntchito chomwe chimakupatsani mwayi woti muyang'ane ntchito yomwe ilipo popanda kuwononga ubwino wa weld.

Ma electrode a A412 ndi njira yabwino kwambiri yogwiritsira ntchito chitsulo chosapanga dzimbiri, zomwe zimapangitsa kuti ntchito yake ikhale yolimba, yogwira ntchito bwino komanso yosinthasintha. Ndi kapangidwe kake kapadera komanso calcium titanium coating, ma electrode a A412 amapangidwa kuti akwaniritse zosowa za ntchito zamakono zogwiritsira ntchito chitsulo, zomwe zimapangitsa kuti pakhale zotsatira zabwino kwambiri pa ntchito zosiyanasiyana zogwiritsira ntchito chitsulo. Kaya mukugwira ntchito zogwiritsa ntchito mafakitale, zamalonda kapena zapakhomo, ma electrode a A412 amapereka kudalirika komanso kulondola kofunikira pa ma weld abwino, zomwe zimapangitsa kuti akhale ofunikira kwa katswiri aliyense wogwiritsa ntchito chitsulo kapena wokonda chitsulo.
