Kufufuza Ubwino wa Ma Electrode a Aluminium mu Kuweta kwa Enicrmo Kochokera ku Nickel

Polumikiza zitsulo za Enicrmo zopangidwa ndi nickel, kusankha ma electrode ndikofunikira kwambiri kuti mupeze weld yapamwamba kwambiri. Njira imodzi yothandiza kwambiri yolumikizira zitsulozi ndikugwiritsa ntchito ndodo zolumikizira za aluminiyamu. Ma electrode a aluminiyamu amapereka zabwino zambiri zomwe zimapangitsa kuti akhale chisankho chodziwika bwino chogwiritsira ntchito zitsulo za Enicrmo zopangidwa ndi nickel.

Ma electrode a aluminiyamu amadziwika ndi mphamvu yawo yabwino kwambiri yoyendetsera magetsi komanso malo osungunuka kwambiri, zomwe zimapangitsa kuti akhale abwino kwambiri polumikiza ma alloy otentha kwambiri monga Enicrmo yochokera ku nickel. Mphamvu yoyendetsera kutentha kwambiri ya ma electrode a aluminiyamu imalola kusamutsa kutentha bwino panthawi yolumikiza, zomwe zimapangitsa kuti dziwe lolumikizira likhale lokhazikika komanso lolamulidwa. Izi ndizofunikira kwambiri mukamagwiritsa ntchito ma alloy a Enicrmo ochokera ku nickel, chifukwa magawo a welding ayenera kuyendetsedwa bwino kuti apewe mavuto monga kusweka ndi kusinthika.

Kuwonjezera pa mphamvu zabwino kwambiri zotenthetsera, ma electrode a aluminiyamu alinso ndi mphamvu zabwino zotsutsana ndi dzimbiri komanso okosijeni. Ichi ndi chinthu chofunikira kwambiri polumikiza ma alloy a Enicrmo okhala ndi nickel, chifukwa zinthuzi nthawi zambiri zimagwiritsidwa ntchito kutentha kwambiri komanso m'malo owononga. Kugwiritsa ntchito ma electrode a aluminiyamu kumathandiza kuonetsetsa kuti ma weld amasunga umphumphu wawo komanso magwiridwe antchito ngakhale pakakhala zovuta pakugwira ntchito.

Kuphatikiza apo, ma electrode a aluminiyamu amadziwika kuti ali ndi hydrogen yochepa, zomwe ndizofunikira kwambiri popewa ming'alu yomwe imabwera chifukwa cha hydrogen mu ma weld. Izi ndizofunikira kwambiri polumikiza ma alloy a Enicrmo okhala ndi nickel, chifukwa zinthuzi zimatha kusweka mosavuta ndi hydrogen. Pogwiritsa ntchito ma electrode a aluminiyamu, ma weld amatha kuchepetsa chiopsezo cha zolakwika zokhudzana ndi hydrogen ndikuwonetsetsa kuti malo olumikizirana a welded ndi odalirika kwa nthawi yayitali.

Mwachidule, kugwiritsa ntchito ma electrode a aluminiyamu powotcherera ma alloy a Enicrmo okhala ndi nickel kumapereka zabwino zambiri, kuphatikizapo kutentha kwabwino kwambiri, kukana dzimbiri komanso kuchepa kwa haidrojeni. Ubwino uwu umapangitsa ma electrode a aluminiyamu kukhala chisankho chabwino kwambiri chopezera ma weld apamwamba kwambiri pakugwiritsa ntchito zovuta zomwe zimaphatikizapo ma alloy a Enicrmo okhala ndi nickel. Pogwiritsa ntchito mawonekedwe apadera a ma electrode a aluminiyamu, owotcherera amatha kutsimikizira kuti weld ndi yolimba komanso imagwira ntchito bwino ngakhale m'malo ovuta kwambiri.
