AWS A5.1 E7015 is low-hydrogen sodium coated carbon steel electrode.
E7015 vuam electrode yuav tsum tau ua ntawm DCEP.Nws muaj cov vuam siv tau zoo heev uas ua rau nws ua tau txhua txoj haujlwm vuam, muaj qhov ruaj khov arc, tshem tawm ntawm slag yog ib qho yooj yim thiab tsis muaj spatter.Cov hlau deposited muaj zoo mechanical kev ua tau zoo thiab tawg-ua hauj, uas muaj zoo kub tsis tshua muaj toughness.
Daim ntawv thov
AWS A5.1 E7015 yog siv nyob rau hauv vuam nruab nrab-carbon steel thiab low-alloy lug xws li 16Mn, 09Mn2Si, 09Mn2V thiab cov hlau siv nyob rau hauv shipbuilding xws li A, B, D, E. Nws kuj yog siv nyob rau hauv tuab steel daim hlau thiab cov carbon steel qauv uas nyuaj rau weld.

Nco tseg:
1. Cov electrode yuav tsum tau preheated ntawm qhov kub ntawm 350 ° C rau 1 teev.Preheat tus pas nrig thaum twg nws siv.
2. Cov impurities xws li xeb, roj stains thiab ya raws yuav tsum tau muab tshem tawm ntawm cov khoom ua haujlwm.
3. luv arc yuav tsum tau ua vuam.Txoj kev nqaim weld yog nyiam.
