Ubushyuhe buke bwo gusudira Electrode
W707
GB / T E5015-G
AWS A5.5 E7015-G
Ibisobanuro: W707 ni electrode yubushyuhe bwo hasi hamwe na sodium ya hydrogène nkeya.Koresha DCEP (itaziguye ya electrode nziza) kandi irashobora gusudira mumyanya yose.Icyuma cyabitswe kiracyafite ingaruka nziza kuri -70 ° C.
Gusaba: Byakoreshejwe mu gusudira ubushyuhe buke nka 2.5Ni.
Ibigize imiti yicyuma (%):
| C | Mn | Si | Ni | S | P |
| .080.08 | ≤1.25 | 60.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Ibikoresho bya tekinike yicyuma gisudira:
| Ikizamini | Imbaraga Mpa | Tanga imbaraga Mpa | Kurambura % | Agaciro k'ingaruka (J) -70 ℃ |
| Bijejwe | 90490 | 90390 | ≥22 | ≥27 |
Diffusion hydrogène yibikoresho byabitswe: ≤6.0mL / 100g (uburyo bwa glycerine) cyangwa ≤10mL / 100g (uburyo bwa mercure cyangwa gaz chromatografiya)
Igenzura rya X-ray: I amanota
Icyifuzo kigezweho:
| （Mm） Diameter | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| A） Kuzenguruka | 40 ~ 70 | 70 ~ 100 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Icyitonderwa:
1. Electrode igomba gutekwa kumasaha 1 kuri 350 ℃ mbere yo gusudira;
2. Gerageza gukoresha ingufu z'umurongo muto mugihe cyo gusudira, ibyiciro byinshi hamwe no gusudira byinshi.
