Electrode e tlase ea Alloy Steel Welding
J707RH
GB/T E7015-G
AWS E10015-G
Tlhaloso: J707RH ke motlakase o phahameng oa ultra-low hydrogen e nang le coating e tlaase ea hydrogen sodium.Sebelisa DCEP (electrode e nepahetseng ea hona joale e nepahetseng) 'me e ka chesetsoa maemong ohle. Ts'ebetso ea ts'ebetso ea welding e ntle.Ho kobeha ho batang, ho hanyetsa ho phatloha le ho hanyetsa ho phatloha ha manonyeletso a cheselitsoeng ho molemo.Tšepe e kentsoeng e na le polasetiki e kholo le ho tiea.
Kopo: E sebelisoa bakeng sa ho cheselletsa meaho ea li-hull, hape e loketse ho cheselletsa meaho ea bohlokoa ea tšepe ea Rp0.2≥590MPa e matla a phahameng.
Sebopeho sa lik'hemik'hale tsa tšepe ea weld(%):
| C | Mn | Cr | Si | Ni | Mo | S | P | S + P |
| ≤0.10 | 1.20 ~ 1,60 | 0.08 ~ 0.20 | 0,30 ~ 0,60 | 1.40 ~ 2.00 | 0,25 ~ 0,50 | ≤0.020 | ≤0.020 | ≤0.035 |
Mechine ea tšepe ea weld:
| Ntho ea teko | Matla a tšepe Mpa | Ho hlahisa matla Mpa | Elongation % | Boleng ba tšusumetso (J) -50 ℃ |
| Guaranteed | ≥690 | ≥590 | ≥15 | ≥34 |
Diffusion hydrogen content of deposited metal: ≤4.1mL/100g (mercury or gas chromatography method)
Tlhahlobo ea X-ray: Ke ea sehlopheng
Nako e khothalelitsoeng:
| (mm) Bophara ba molamu | 4.0 | 5.0 |
| (A) Welding Current | 160 ~ 180 | 180 ~ 220 |
Tlhokomeliso:
1. Electrode e tlameha ho apehoa lihora tse 2 ho 400 ℃ pele ho ts'ebetso ea welding;
2. Ho bohlokoa ho hloekisa mafome, sekala sa oli, metsi le litšila likarolong tsa ho cheseletsa pele ho tjheseletsa;
3. Sebelisa ts'ebetso e khuts'oane ea arc ha u cheselletsa.Tsela e moqotetsane ea ho tjheseletsa e nepahetse.
