Kufotokozera: J506NiMA ndi J507NiMA ndi ma elekitirodi achitsulo otsika kwambiri a haidrojeni okhala ndi aloyi.Chitsulo choyikidwa chimakhala ndi pulasitiki wabwino kwambiri, kulimba kwa kutentha pang'ono komanso kukana kwa ming'alu, ndipo chitha kuwotcherera m'malo onse.Chophimbacho chimalimbana ndi kuyamwa kwa chinyezi.Pambuyo pa electrode yophikidwa pa 400 ° C x 1h ndikuyimitsidwa pamalo omwe ali ndi chinyezi chapafupi ≥ 80% kwa maola 4, chinyontho cha chophimbacho chimakwaniritsabe zofunikira zogwiritsira ntchito.

Ntchito: Amagwiritsidwa ntchito powotcherera nsanja zamafuta, zombo, zombo zapamadzi, ndi zida zina zopangidwa ndicarbon steel ndi low alloy steel.

Chemical zikuchokera weld zitsulo (%):

Zimango za weld zitsulo:

Kuphatikizika kwa haidrojeni muzitsulo zoyikidwa: ≤5.0mL/100g (gasi chromatography kapena njira ya mercury)

Chinyezi cha zokutira ma electrode: ≤0.30%

Kuwunika kwa X-ray: Ndimapanga

Zomwe tikulimbikitsidwa:

Zindikirani:

1. Elekitirodi ayenera kuphika kwa ola 1 pa 350 ~ 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.
