Buku Lothandiza Kwambiri la Ndodo Zowotcherera Zitsulo Zotentha Kwambiri

Mukalumikiza chitsulo pa kutentha kochepa, kugwiritsa ntchito elekitirodi yoyenera ndikofunikira kwambiri kuti mupange weld yolimba komanso yolimba.W107 (AWS E7015-C2L) electrode yachitsulo yotsika kutenthandi imodzi mwa ma electrode otere omwe amadziwika kwambiri pamsika. Ndodo yolumikizira iyi yapangidwa ndi hydrogen sodium yochepa ndipo ndi yoyenera kwambiri kulumikiza m'malo otentha kwambiri.

Ma electrode a W107 adapangidwa mwapadera kuti asunge kulimba kwamphamvu ngakhale pa -100°C, zomwe zimapangitsa kuti ikhale chisankho chodalirika chogwiritsira ntchito kuwotcherera m'malo ozizira kwambiri. Kutha kwake kupirira kutentha kotsika koteroko kumapangitsa kuti ikhale chida chofunikira kwambiri m'mafakitale monga zomangamanga, mafuta ndi gasi, komanso opanga magalimoto, komwe kuwotcherera m'malo omwe ali pansi pa zero ndi kofala.

Chimodzi mwa zinthu zazikulu za electrode ya W107 ndi kusinthasintha kwake m'malo olumikizirana. Kaya ndi yolumikiza molunjika, molunjika, pamwamba kapena molunjika, electrode iyi ingagwiritsidwe ntchito m'malo onse, kupatsa olumikiza kusinthasintha komanso kosavuta kugwira ntchito pamapulojekiti osiyanasiyana.

Ponena za magawo a welding, electrode ya W107 imagwiritsidwa ntchito bwino limodzi ndi DCEP (DC electrode positive electrode) kuti zitsimikizire kuti mawonekedwe a arc ndi okhazikika komanso ntchito zowotcherera zimakhala zosavuta. Izi zimapangitsa kuti ikhale yoyenera kwa onse odziwa bwino ntchito yowotcherera komanso oyamba kumene chifukwa ndi yosavuta kugwiritsa ntchito komanso imagwira ntchito bwino.

Ponena za ubwino wa chitsulo chosungidwa, ma electrode a W107 amapereka ma weld amphamvu komanso odalirika omwe amakwaniritsa miyezo yapamwamba yofunikira pakuwotcherera zitsulo zotentha pang'ono. Chophimba chake chochepa cha hydrogen sodium chimawonjezeranso kuthekera kwake kopanga ma weld oyera komanso olondola, kuchepetsa chiopsezo cha zolakwika ndikuwonetsetsa kuti cholumikizira cholumikizidwacho chikuyenda bwino.

Mwachidule, W107 (AWS E7015-C2L) Low Temperature Steel Electrode ndiyo chisankho choyamba cha osonkha ma waya omwe amafunikira ma electrode odalirika komanso ogwira ntchito bwino kuti awotchuthire m'malo otentha kwambiri. Kulimba kwake kwabwino kwambiri, malo osonkha ma waya osiyanasiyana, komanso kugwirizana ndi DCEP zimapangitsa kuti ikhale chinthu chamtengo wapatali pa ntchito iliyonse yosonkha ma waya yomwe imafuna mphamvu ndi kulimba m'malo ozizira. Kaya mukugwira ntchito pa mapaipi, nyumba zachitsulo kapena makina olemera, ndodo zosonkha ma waya za W107 ndi bwenzi lanu lodalirika la ma weld apamwamba kwambiri pakugwiritsa ntchito chitsulo chotentha kwambiri.
