I-Nickel ne-Nickel Alloy Welding Electrode
Ni327-6
I-GB/T ENi6620
I-AWS A5.11 ENCrMo-6
Incazelo: I-Ni327 -6 i-electrode esekwe ku-nickel ene-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode yamanje eqondilepositive).Insimbi efakiwe inopulasitiki omuhle kakhulu, ukuqina kanye nokumelana nokuqhekeka.Insimbi ediphozithiwe inomugqa wokunweba we-coefficient ofana naleyo yensimbi, futhi inamandla aphezulu kanye nokumelana nokugqwala okuqinile ekamelweni lokushisa kanye nezinga lokushisa eliphezulu.
Isicelo: Isetshenziselwa ukushisela insimbi ye-Ni9%, futhi ingasetshenziselwa ukushisela izinsimbi ezihlukene kanye nama-alloys okunzima ukushisela.
Ukwakheka kwamakhemikhali ensimbi ye-weld(%):

Izici zemishini ye-weld metal:
Into yokuhlola | Amandla aqinile Mpa | Amandla esivuno Mpa | Ukwelula % |
Kuqinisekisiwe | ≥620 | ≥350 | ≥32 |
Okwamanje okunconyiwe:
Ububanzi benduku (mm) | 2.5 | 3.2 | 4.0 |
Welding current (A) | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Isaziso:
1. I-electrode kufanele ibhakwe ihora elingu-1 endaweni engaba ngu-300 ℃ ngaphambi kokusebenza kokushisela.Zama ukusebenzisa i-arc emfushane ukushisela;
2. Kubalulekile ukuhlanza okugqwalile, uwoyela, amanzi, nokungcola ezingxenyeni zokushisela ngaphambi kokushisela.
3. Zama ukusebenzisa amandla kalayini omncane lapho welding, multi-layer kanye multi-pass welding.
