COV KEV CEEV FAJ:

⒈ vuam electrode yuav tsum tau 300 ~ 350 ℃ ci 1 teev.

⒉ Ua ntej vuam cov khoom ua haujlwm kom preheated rau 300 ℃ saum toj no, tom qab vuam, kev kho cua sov sib txawv tuaj yeem tau txais qhov nyuaj tsim nyog.

Cov Qws Welding AWS E6010:

AWS E6010 yog ib hom cellulose-Na hom vuam electrodes, tshwj xeeb rau DC. Nws siv cov thev naus laus zis txawv teb chaws siab heev, nws muaj ARC tob tob, ob peb slags, yooj yim detachability, vuam zoo, zoo nkauj ua tau zoo. Nws tuaj yeem siv rau vuam rau txhua qhov chaw, ntsug nce thiab nqis txoj haujlwm vuam thiab lwm yam nws tuaj yeem ncav cuag cov nyhuv uas ib sab vuam ob sab tsim.

DAIM NTAWV THOV:

Cov pas nrig vuam AWS E6010 feem ntau yog rau kev vuam cov yeeb nkab carbon lossis cov khoom siv tib yam, thaub qab weld / filling weld / cosmetic weld rau cov qauv hlau hauv qab.

CEEB TOOM:

1. Nws yooj yim rau raug dej noo, thov khaws cia rau hauv qhov chaw qhuav.

2. Nws xav tau cua sov thaum pob tawg lossis dej noo nqus, qhov kub cua sov yuav tsum nyob nruab nrab ntawm 70C txog 80C, lub sijhawm cua sov yuav tsum yog txij li 0.5 txog 1 teev.

3. Thaum siv cov electrodes vuam 5.0 hli, nws zoo dua los siv cov thrust siab, qis-tam sim no, txhawm rau txhim kho kev ua haujlwm vuam.
