Low Kutentha Zitsulo kuwotcherera Electrode
W107
GB/T E5015-C2L
AWS A5.5 E7015-C2L
Kufotokozera: W107 ndi electrode yachitsulo yotsika kutentha yokhala ndi zokutira za hydrogen sodium.Gwiritsani ntchito DCEP (mwachindunji pakalipano ma elekitirodi abwino) ndipo mutha kuwotcherera m'malo onse.Chitsulo choyikidwa chikadali ndi kulimba kwabwino kwa -100 ° C.
Ntchito: Ntchito kuwotcherera otsika kutentha zitsulo monga 3.5Ni.
Chemical zikuchokera weld zitsulo (%):
| C | Mn | Si | Ni | S | P |
| ≤0.05 | ≤1.25 | ≤0.60 | 3.00 ~ 3.75 | ≤0.020 | ≤0.025 |
Zimango za weld zitsulo:
|
Yesani chinthu |
Kulimba kwamakokedwe Mpa |
Zokolola mphamvu Mpa | Elongation% | Mtengo (J) -100 ℃ |
|
Zotsimikizika | ≥490 | ≥390 | ≥22 | ≥27 |
Kuphatikizika kwa haidrojeni muzitsulo zoyikidwa: ≤4.0mL/100g (njira ya glycerin) kapena ≤7.0mL/100g (njira ya mercury kapena gas chromatography)
Kuwunika kwa X-ray: Ndimapanga
Zomwe tikulimbikitsidwa:
| (mm) Ndodo diameter | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Welding Current | 40-70 | 70-90 | 90-130 | 140 ~ 180 | 180 ~ 240 |
Zindikirani:
- Elekitirodi ayenera kuphika kwa ola 1 pa 350 ℃ pamaso kuwotcherera ntchito;
- Ndikofunikira kuyeretsa dzimbiri, sikelo yamafuta, madzi, ndi zonyansa pazigawo zowotcherera musanawotcherera;
- Yesani kugwiritsa ntchito mphamvu ya mzere waung'ono powotcherera, ma multilayer ndi ma pass-pass kuwotcherera.
