J607
I-GB/T E6015-D1
I-AWS E9015-D1
Incazelo: I-J607 iyi-electrode yensimbi ene-alloy ephansi ene-low-hydrogen coating.Sebenzisa i-DCEP (i-electrode eqondile yamanje eqondile), futhi ingashiselwa kuzo zonke izikhundla.
Isicelo: Isetshenziselwa ukushisela i-medium carbon steel kanye ne-low-alloy high-strength steel izakhiwo zamandla ahambisanayo, njenge-Q420, njll.
Ukwakheka kwamakhemikhali ensimbi ye-weld(%):
| C | Mn | Si | Mo | S | P |
| ≤0.12 | 1.25 ~ 1.75 | ≤0.60 | 0.25 ~ 0.45 | ≤0.035 | ≤0.035 |
Izici zemishini ye-weld metal:
| Into yokuhlola | Amandla aqinile Mpa | Amandla esivuno Mpa | Ukwelula % | Inani lomthelela (J) -30 ℃ |
| Kuqinisekisiwe | ≥590 | ≥490 | ≥15 | ≥27 |
| Ihloliwe | 620 ~ 680 | ≥500 | 20 ~ 28 | ≥27 |
Okuqukethwe kwe-hydrogen okusabalaliswa kwensimbi efakiwe: ≤4.0mL/100g (indlela ye-glycerin)
Ukuhlolwa kwe-X-ray: I grade
Okwamanje okunconyiwe:
| (mm) Ububanzi benduku | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 | 5.8 |
| (A) I-Welding Yamanje | 60 ~ 80 | 70 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 | 210 ~ 260 |
Isaziso:
1. I-electrode kufanele ibhakwe ihora elingu-1 ku-350 ℃ ngaphambi kokusebenza kokushisela;
2. Kubalulekile ukuhlanza okugqwalile, isikali sikawoyela, amanzi, nokungcola ezingxenyeni zokushisela ngaphambi kokushisela;
3. Sebenzisa ukusebenza kwe-arc emfushane lapho ushisela.Ithrekhi yokushisela emincane ilungile.
