Humilis Alloy Steel Welding Electrode
J707
GB/T E7015-D2
AWS E10015-D2
Descriptio: J707 Electrodam est humilis mixtura altae vires chalybis cum humili-hydrogenis sodium efficiens.Utere DCEP (electro positivo directo) et in omnibus positionibus coniungi potest.Cum opus est, nuptiae ante glutino temperari et post glutino praevenire possunt.
Applicatio: Maxime adhibenda est ad glutino 15MnMoV, 14MnMoVB, 18MnMoNb et alia structurae ferro admixto ignobili.Iuncta compages sub conditione glutino vel temperantia laborare potest (500~ 650 ).

Animadverte:
1. Electrodum coquendum est per 1 horae 350~ 380℃ ante operationem glutinum;
2. Essentiale est mundare ferruginem, squamam olei, aquam et immunditias in partibus glutino ante glutino;
3. Utere operationi arcuum brevibus glutino.Vestigium glutino angustum proprium est.
