I-Low Temperature Steel Welding Electrode
W707
I-GB/T E5015-G
I-AWS A5.5 E7015-G
Incazelo: I-W707 iyi-electrode yensimbi enezinga lokushisa eliphansi ene-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode yamanje eqondile) futhi ingashiselelwa kuzo zonke izikhundla.Insimbi efakiwe isenokuqina okuhle komthelela ku -70°C.
Isicelo: Isetshenziselwa ukushisela insimbi yokushisa ephansi efana ne-2.5Ni.
Ukwakheka kwamakhemikhali ensimbi ye-weld(%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Izici zemishini ye-weld metal:
| Into yokuhlola | Amandla aqinile Mpa | Amandla esivuno Mpa | Ukwelula % | Inani lomthelela (J) -70 ℃ |
| Kuqinisekisiwe | ≥490 | ≥390 | ≥22 | ≥27 |
Okuqukethwe kwe-hydrogen yokusabalalisa kwensimbi efakiwe: ≤6.0mL/100g (indlela ye-glycerin) noma ≤10mL/100g (i-mercury noma indlela ye-gas chromatography)
Ukuhlolwa kwe-X-ray: I grade
Okwamanje okunconyiwe:
| (mm) Ububanzi benduku | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) I-Welding Yamanje | 40 ~ 70 | 70 ~ 100 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Isaziso:
1. I-electrode kufanele ibhakwe ihora elingu-1 ku-350 ℃ ngaphambi kokusebenza kokushisela;
2. Zama ukusebenzisa amandla kalayini omncane lapho ushisela, i-multi-layer kanye ne-multi-pass welding.
