E7028 electrode yowotcherera

AWS A5.1 E7028 Ndodo Yowotchereras

Choyeretsera choyeretsera AWS A5.1 E7028 ndi electrode yachitsulo cha kaboni yokhala ndi haidrojeni-potaziyamu-chitsulo chophimbidwa ndi ufa wochepa. Ufa wachitsulo womwe uli mu chophimbacho umawonjezera kuchuluka kwa chosungidwacho mpaka 180%. Chili ndi kugwiritsidwa ntchito bwino kwambiri komwe kumachilola kukhala ndi arc yokhazikika, yothira madzi pang'ono, kuchotsa slag ndikosavuta ndipo chimagwira ntchito yonse. Chitsulo choyikidwacho chili ndi mphamvu zabwino zamakanika zomwe zimapereka kulimba kwabwino kwambiri kutentha kochepa.

Kugwiritsa ntchito

AWS A5.1 E7028 imagwiritsidwa ntchito polumikiza fillets zathyathyathya ndi zathyathyathya m'nyumba zopangidwa ndi chitsulo cha kaboni ndi zitsulo zochepa monga zitsulo za 16Mn, 09Mn2Si ndi A, B, D, E zomwe zimagwiritsidwa ntchito popanga zombo.

Katundu wa Makina a Chitsulo Chosungidwa

Ma Reference Current (DC)

Zolemba:

1. Electrode iyenera kutenthedwa pa kutentha kwa 350°C kwa ola limodzi. Yatsani ndodo nthawi iliyonse ikagwiritsidwa ntchito.

2. Zonyansa monga dzimbiri, madontho a mafuta ndi chinyezi ziyenera kuchotsedwa pa ntchitoyo.

3. Mzere waufupi umafunika kuti munthu agwiritse ntchito kuwotcherera. Njira yopapatiza yowotcherera ndiyo yabwino kwambiri.

Kusunga ndi kuphika kwa E7028 Welding Electrode

Popeza E7016 ndi electrode yochepa ya hydrogen, imafunakuphika/kuumitsamusanagwiritse ntchito. Kutentha koyenera kowumitsa kapena kuphika kwa ndodo ya E7028 malinga ndi AWS A5.1, Table 1.3 ndi 500-800°F (260-425°C) kwa maola 1-2.

Ma electrode ophikidwa kapena ouma ayenera kusungidwa mu uvuni wonyamulika pa kutentha kwa 50-250°F (30-140°C) panthawi yogwiritsidwa ntchito. Ma electrode osagwiritsidwa ntchito ayenera kubwezeretsedwa ku uvuni wokhazikika.
