AWS A5.13 ECoCr-A Kulumikizana kolimba kwa ma elekitirodi opangira ma weld
Ntchito & Standard
GEH-SL6 ndi mtundu wa kuwotcherera kwa valavu ya injini, tsamba la turbine, kutentha kwakukulu ndi valavu yothamanga kwambiri, kufa kwamoto wotentha ndi zina zotentha kwambiri komanso kukana kwa dzimbiri. Pakuwotcherera, kuti muphatikizidwe mwamphamvu ndi gawo lapansi, ndikofunikira kuwotcherera mozama kulowa. Chifukwa chake, njira yayifupi yowotcherera arc ingatengedwe. Kachiwiri, pofuna kuthana ndi vuto la dziwe lakuya komanso zinthu zoyambira kwambiri zomwe zimasungunuka mu weld panthawi yowotcherera arc, kuchuluka kwa dilution ndikwambiri. Kuperewera kwa zigawo zogwira ntchito mu weld layer kumachepetsa vuto la kukana kuvala. Ayenera kugwiritsa ntchito njira zingapo, zosanjikiza zambiri. Mwa njira iyi, osati zigawo zothandiza ndi kuvala kukana mu backsurfacing wosanjikiza kuwonjezeka wosanjikiza ndi wosanjikiza. Kuphatikiza apo, zigawo zingapo zoyambirira za pamwamba zimagwiranso ntchito ngati gawo losinthira, kuchepetsa kung'ambika komwe kumachitika chifukwa cha kusiyana kwa kuchuluka kwamafuta pakati pa zigawo ziwiri zoyandikana. Pakalipano, njira yoyendetsera mizere yowongoka, njira yoyendetsera nsomba, njira yosuntha ya herringbone kapena njira yaufupi ya arc agitation movement iyenera kutsatiridwa.
Mawonekedwe
Ichi ndi titaniyamu calcium yokutira cobalt m'munsi electrode, yoyenera DC reverse kulumikiza, zitsulo pamwamba akhoza kukhalabe bwino kuvala kukana ndi dzimbiri kukana pa 650 ℃, kukana mphamvu ndi kuzizira ndi kutentha kukana kutopa. Itha kugwiritsidwa ntchito pazofunikira zozungulira 650 ℃ ntchito imatha kukhalabe yabwino kuvala kukana ndi kukana dzimbiri, komanso momwe zimakhudzira komanso kuzizira ndi malo akutenthedwa, zitha kukhala ndi ntchito yabwino.
