AWS A5.1 E7015 ndi low-hydrogen sodium yokutidwa carbon steel electrode.
Elekitirodi yowotcherera ya E7015 iyenera kugwiritsidwa ntchito pa DCEP.Ili ndi ma welding abwino kwambiri omwe amawathandiza kuti azitha kuwotcherera malo onse, ali ndi arc yokhazikika, kuchotsa slag ndikosavuta komanso kumakhala ndi spatter yochepa.Chitsulo choyikidwa chimakhala ndi machitidwe abwino amakina komanso kukana ming'alu, zomwe zimapereka kulimba kwa kutentha kochepa.
Kugwiritsa ntchito
AWS A5.1 E7015 imagwiritsidwa ntchito powotcherera zitsulo zapakati-carbon ndi zocheperako monga 16Mn, 09Mn2Si, 09Mn2V ndi zitsulo zomwe zimagwiritsidwa ntchito popanga zombo monga A, B, D, E. Amagwiritsidwanso ntchito m'mbale zachitsulo zokhuthala ndi zida za carbon steel zomwe zimakhala zovuta kuwotcherera.

Ndemanga:
1. Elekitirodi iyenera kutenthedwa pa kutentha kwa 350 ° C kwa ola limodzi.Preheat ndodo nthawi iliyonse ikagwiritsidwa ntchito.
2. Zonyansa monga dzimbiri, madontho amafuta ndi chinyezi ziyenera kuchotsedwa pa ntchitoyo.
3. Short arc chofunika kuchita kuwotcherera.Njira yopapatiza yowotcherera ndiyokonda.
