Intsimbi yobushushu obuphantsiUkuweldaI-Electrode
W707Ni
GB/T E5515-C1
Inkcazo: I-W707Ni i-electrode yensimbi ephantsi yobushushu equkethe i-Ni kwi-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode echanekileyo yangoku) kwaye inokudityaniswa kuzo zonke izikhundla.Isinyithi esidipozithiweyo sisenempembelelo entle yokuqina kwi -70°C.
Isicelo: Isetyenziselwa ukuwelda intsimbi yobushushu obuphantsi njenge-2.5Ni.
Ukwakhiwa kweekhemikhali zentsimbi edibeneyo(%):
| C | Mn | Si | Ni | S | P |
| ≤0.12 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Iimpawu zobuchwephesha bentsimbi ye-weld:
| Into yovavanyo | Tensile strength Mpa | Unikeze Amandla Mpa | Elongation % | Ixabiso lempembelelo (J) -70℃ |
| Iqinisekisiwe | ≥540 | ≥440 | ≥17 | ≥27 |
Umxholo we-hydrogen we-Diffusion yensimbi egciniweyo: ≤6.0mL / 100g (indlela ye-glycerin) okanye ≤10mL / 100g (i-mercury okanye indlela ye-chromatography yegesi)
Ukuhlolwa kwe-X-reyi: I grade
yangoku eCetyisiweyo:
| (mm) Intonga yobubanzi | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) I-Welding yangoku | 40 ~ 70 | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Isaziso:
- I-electrode kufuneka ibhakwe ngeyure eyi-1 kwi-350 ℃ ngaphambi kokusebenza kwe-welding;
- Kubalulekile ukucoca umhlwa, isikali se-oyile, amanzi, kunye nokungcola kwiindawo zokuwelda phambi kokuba udibanise;
- Zama ukusebenzisa amandla omgca omncinci xa udibanisa, i-multi-layer kunye ne-multi-pass welding.
