Low Kutentha ChitsuloKuwotchereraElectrode
W707N
GB/T E5515-C1
Kufotokozera: W707Ni ndi electrode yachitsulo yotsika kutentha yokhala ndi Ni mu zokutira zotsika za haidrojeni.Gwiritsani ntchito DCEP (mwachindunji pakalipano ma elekitirodi abwino) ndipo mutha kuwotcherera m'malo onse.Chitsulo choyikidwa chikadali ndi kulimba kwabwino kwa -70 ° C.
Ntchito: Ntchito kuwotcherera otsika kutentha zitsulo monga 2.5Ni.
Chemical zikuchokera weld zitsulo (%):
| C | Mn | Si | Ni | S | P |
| ≤0.12 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Zimango za weld zitsulo:
| Yesani chinthu | Kulimba kwamakokedwe Mpa | Zokolola mphamvu Mpa | Elongation % | Mtengo (J) -70 ℃ |
| Zotsimikizika | ≥540 | ≥440 | ≥17 | ≥27 |
Kuphatikizika kwa haidrojeni muzitsulo zoyikidwa: ≤6.0mL/100g (njira ya glycerin) kapena ≤10mL/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 | 60-90 | 90-120 | 140 ~ 180 | 170 ~ 210 |
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.
