AWS E10015-G Kulimba Kwambiri Kwambiri-Low Hydrogen Electrode J707RH Low Alloy Steel Welding Rod

Low Alloy Steel Welding Electrode

J707RH                               

GB/T E7015-G

AWS E10015-G

Kufotokozera: J707RH ndi cholimba kwambiri chotsika kwambiri cha hydrogen electrode chokhala ndi zokutira za hydrogen sodium.Gwiritsani ntchito DCEP (mwachindunji panopa electrode positive) ndipo akhoza welded mu maudindo onse.The kuwotcherera ndondomeko ntchito bwino.Kupindika kozizira, kukana ming'alu ndi kukana kuphulika kwa ma welds ndi abwino.Chitsulo choyikidwa chili ndi pulasitiki wamkulu komanso kulimba.

Ntchito: Imagwiritsidwa ntchito pakuwotcherera zinyumba zamadzi, komanso ndiyoyenera kuwotcherera zinthu zofunika za Rp0.2≥590MPa zitsulo zolimba kwambiri.

Chemical zikuchokera weld zitsulo (%):

Zimango za weld zitsulo:

Kuphatikizika kwa haidrojeni muzitsulo zoyikidwa: ≤4.1mL/100g (njira ya mercury kapena gas chromatography)

Kuwunika kwa X-ray: Ndimapanga

Zomwe tikulimbikitsidwa:

Zindikirani:

1. Elekitirodi ayenera kuphika kwa 2 ora pa 400 ℃ pamaso kuwotcherera ntchito;

2. Ndikofunikira kuyeretsa dzimbiri, sikelo yamafuta, madzi, ndi zonyansa pazigawo zowotcherera musanawotchere;

3. Gwiritsani ntchito kachipangizo kakang'ono powotcherera.Njira yopapatiza yowotcherera ndiyoyenera.
