I-Low Temperature Steel Welding Electrode
W607
I-GB/T E5015-G
I-AWS A5.5 E7015-G
Incazelo: I-W607 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 inokuqina okuhle komthelela ku -60°C.
Isicelo: Isetshenziselwa ukushisela insimbi yokushisa ephansi efana ne-09MnD.
Ukwakheka kwamakhemikhali ensimbi ye-weld(%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.65 | ≤0.60 | 0.50 ~ 2.50 | ≤0.020 | ≤0.025 |
Izici zemishini ye-weld metal:
| Into yokuhlola | Amandla aqinile Mpa | Amandla esivuno Mpa | Ukwelula % | Inani lomthelela (J) -60 ℃ |
| 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 | 60 ~ 90 | 100 ~ 120 | 140 ~ 170 | 170 ~ 200 |
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. Ingxenye eshiselwe ingashiswa ngaphambi kuka-150 ° C ngaphambi kokushisela ukuvimbela ukuqhekeka.
