Low Kutentha Zitsulo kuwotcherera Electrode
W707
GB/T E5015-G
AWS A5.5 E7015-G
Kufotokozera: W707 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 -70 ° C.
Ntchito: Ntchito kuwotcherera otsika kutentha zitsulo monga 2.5Ni.
Chemical zikuchokera weld zitsulo (%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤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 | ≥490 | ≥390 | ≥22 | ≥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 | 70 ~ 100 | 90-120 | 140 ~ 180 | 170 ~ 210 |
Zindikirani:
1. Elekitirodi ayenera kuphika kwa ola 1 pa 350 ℃ pamaso kuwotcherera ntchito;
2. Yesani kugwiritsa ntchito mphamvu ya mzere waung'ono powotcherera, ma multilayer ndi ma pass-pass kuwotcherera.
