Ndodo Yowetsera Yotsika ya AWS E10015-D2 Yokhala ndi Mphete Yotsika ya Hydrogen Welding Stick Electrodes

Low Aloyi Zitsulo kuwotcherera elekitirodi

J707                               

GB/T E7015-D2

AWS E10015-D2

Kufotokozera: J707 ndi electrode yachitsulo yolimba kwambiri yokhala ndi chofunda chochepa cha sodium. Gwiritsani ntchito DCEP (electrode ya direct current positive), ndipo ikhoza kulumikizidwa m'malo onse. Ngati pakufunika, zolumikizira zimatha kutenthedwa musanazigwiritse ntchito ndikuzitenthetsa pambuyo pozilumikiza.

Kugwiritsa Ntchito: Amagwiritsidwa ntchito makamaka powotcherera 15MnMoV, 14MnMoVB, 18MnMoNb ndi zina zopangidwa ndi chitsulo chotsika. Kapangidwe kowotcherera kamatha kugwira ntchito ngati kowotcherera kapena kotenthetsera (500 ~ 650 ℃).

Kapangidwe ka mankhwala a chitsulo chosungunula (%):

Kapangidwe ka makina a chitsulo chosungunula:

Kuchuluka kwa haidrojeni m'chitsulo chosungidwa: ≤4.0mL/100g (njira ya glycerin)

Kuwunika kwa X-ray: Giredi I

Mphamvu yovomerezeka:

Zindikirani:

1. Electrode iyenera kuphikidwa kwa ola limodzi pa kutentha kwa 350 ~380℃ isanayambe kuwotcherera;

2. Ndikofunikira kuyeretsa dzimbiri, mafuta oyezera, madzi, ndi zinyalala pa zipangizo zowotcherera musanawotchetse;

3. Gwiritsani ntchito njira yochepetsera arc polumikiza. Njira yopapatiza yolumikizira ndi yoyenera.
