Ala Alloy Steel Welding Electrode
J707RH
GB/T E7015-G
AWS E10015-G
Nkọwa: J707RH bụ elu siri ike ultra-ala hydrogen electrode na obere hydrogen sodium mkpuchi.Jiri DCEP (direct current electrode positive) na ike welded na niile positions. The ịgbado ọkụ usoro ịrụ ọrụ dị mma.Ntugharị oyi, nkwụsị mgbawa na mgbawa mgbawa nke nkwonkwo welded dị mma.Igwe etinyere ego nwere nnukwu plasticity na ike.
Ngwa: A na-eji ya maka ịgbado ọkụ nke akụkụ hull, ma dịkwa mma maka ịgbado ọkụ nke akụkụ dị mkpa nke Rp0.2≥590MPa ígwè dị elu.
Ngwakọta kemịkalụ nke igwe 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 |
Njirimara nke igwe weld metal:
| Nwalee ihe | Ike ọdụdọ Mpa | Mpụta ike Mpa | Ogologo oge % | Uru mmetụta (J) -50 ℃ |
| Ekwenyere | ≥690 | ≥590 | ≥15 | ≥34 |
Mgbasa hydrogen ọdịnaya nke ọla edobere: ≤4.1mL/100g (mercury ma ọ bụ gas chromatography usoro)
Nyocha x-ray: akara ule
Akwadoro ugbu a:
| (mm) Dayameta mkpanaka | 4.0 | 5.0 |
| (A) Welding Ugbu a | 160 ~ 180 | 180 ~ 220 |
Mara:
1. The electrode ga-abụọ maka 2 hour na 400 ℃ tupu ịgbado ọkụ ọrụ;
2. Ọ dị mkpa iji kpochaa nchara, ọnụ ọgụgụ mmanụ, mmiri, na adịghị ọcha na akụkụ ịgbado ọkụ tupu ịgbado ọkụ;
3. Jiri obere arc arụ ọrụ mgbe ịgbado ọkụ.Ụzọ ịgbado ọkụ dị warara kwesịrị ekwesị.
