Buku Lothandiza Kwambiri la Ndodo Zowotcherera Zitsulo Zotentha Kwambiri

Polumikiza zitsulo zotentha pang'ono, kusankha electrode yoyenera ndikofunikira kwambiri kuti mupeze ma weld apamwamba komanso olimba. W107 (AWS E7015-C2L) ndi electrode yomwe imadziwika bwino pamsika.electrode yachitsulo yotsika kutenthaYapangidwa ndi chophimba cha sodium chochepa cha haidrojeni, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito powotcherera m'malo otentha kwambiri. Yokhoza kusunga kulimba kwabwino mpaka -100°C, electrode ya W107 ndi yankho lodalirika la mapulojekiti owotcherera omwe amafunikira magwiridwe antchito apamwamba kwambiri m'malo ozizira kwambiri.

Ndodo yolumikizira ya W107 yapangidwa mwapadera kuti igwiritsidwe ntchito polumikiza zitsulo zotentha pang'ono ndipo imapereka zotsatira zabwino kwambiri pakukhala ndi mphamvu komanso kulimba. Chophimba chake cha sodium yochepa ya haidrojeni chimatsimikizira kuyamwa kochepa kwa haidrojeni panthawi yolumikiza, zomwe ndizofunikira kuti zisasweke ndikuwonetsetsa kuti cholumikiziracho chikuyenda bwino. Izi zimapangitsa kuti ikhale chisankho choyamba cholumikizira zomangamanga zofunika komanso zinthu zomwe zimakhudzidwa ndi kutentha kochepa, monga matanki a cryogenic, mapaipi ndi zida zomwe zimagwiritsidwa ntchito m'malo ozizira.

Chimodzi mwa zinthu zazikulu za electrode ya W107 ndi kusinthasintha kwake m'malo olumikizirana. Kaya ndi yoyima, yopingasa, yokwera pamwamba kapena yosalala, electrode iyi ingagwiritsidwe ntchito m'malo onse, kupatsa olumikizirana kusinthasintha komanso kosavuta kugwira ntchito pamapulojekiti osiyanasiyana. Kuphatikiza apo, electrodeyi idapangidwa kuti igwiritsidwe ntchito ndi DC Positive Electrode (DCEp) kuti ikwaniritse magwiridwe antchito olumikizirana bwino komanso okhazikika m'malo osiyanasiyana olumikizirana.

Chitsulo chosungidwa cha elekitirodi ya W107 chimasunga kulimba kwamphamvu kwambiri ngakhale kutentha kotsika kwambiri, zomwe zimapangitsa kuti chikhale chosankha chodalirika chogwiritsidwa ntchito pomwe weld imakhudzidwa ndi kuzizira kwambiri. Kulimba kwapadera kumeneku kumatsimikizira kuti weld imasunga kapangidwe kake komanso magwiridwe antchito ake ngakhale m'malo omwe ali pansi pa zero, zomwe zimapangitsa kuti zigawo zolumikizidwa zikhale zodalirika komanso zotetezeka kwa nthawi yayitali.

Mwachidule, W107 (AWS E7015-C2L) Low Temperature Steel Welding Rod ndiye njira yabwino kwambiri yogwiritsira ntchito welding yomwe imafuna magwiridwe antchito apamwamba kwambiri m'malo otentha kwambiri. Chophimba chake chochepa cha hydrogen sodium pamodzi ndi kuthekera kwake kosunga kulimba kwamphamvu pa -100°C zimapangitsa kuti ikhale chisankho chabwino kwambiri kwa oweda omwe akufuna zotsatira zabwino komanso zodalirika m'malo ozizira kwambiri. Chifukwa cha malo ake oweda komanso kugwirizana ndi DCEP, electrode ya W107 imapatsa oweda chidaliro komanso chitsimikizo chomwe amafunikira kuti athe kuthana ndi mapulojekiti oweda zitsulo otentha kwambiri molondola komanso mwaluso.
