I-Electrode yokuWelda yeNickel kunye neNickel Alloy
I-Ni327-6
GB/T ENi6620
I-AWS A5.11 ENiCrMo-6
Inkcazo: I-Ni327 -6 yi-electrode esekelwe kwi-nickel ene-hydrogen sodium coating ephantsi. Sebenzisa i-DCEP (i-electrode yangoku ngqo)intle). Isinyithi esigciniweyo sinobunkunkqele obuhle kakhulu, ukuqina kunye nokumelana nokuqhekeka. Isinyithi esigciniweyo sinomlinganiselo wokwandiswa okuthe ngqo ofana nowentsimbi, kwaye sinamandla aphezulu kunye nokumelana nokugqwala okunamandla kubushushu begumbi kunye nobushushu obuphezulu.
Ukusetyenziswa: Isetyenziselwa ukuwelda intsimbi ye-Ni9%, kwaye ingasetyenziselwa ukuwelda iintsimbi ezahlukeneyo kunye nee-alloys ezinzima ukuwelda.
Ukwakheka kweekhemikhali zesinyithi esijiyiweyo (%):
| C | Mn | Si | Ni | Mo | Fe | Cu |
| ≤0.10 | 2.0 ~ 4.0 | ≤1.0 | ≥55.0 | 5.0 ~ 9.0 | ≤10.0 | ≤0.5 |
| Nb + Ta | W | Cr | S | P | Okunye |
|
| 0.5 ~ 2.0 | 1.0 ~ 2.0 | 12.0 ~ 17.0 | ≤0.015 | ≤0.020 | ≤0.5 |
|
Iimpawu zoomatshini zesinyithi esijijekileyo:
| Into yovavanyo | Tensile strength I-Mpa | Unikeze Amandla I-Mpa | Ukwandiswa % |
| Iqinisekisiwe | ≥620 | ≥350 | ≥32 |
I-current ecetyiswayo:
| Ububanzi bentonga （mm） | 2.5 | 3.2 | 4.0 |
| Ukuwelda komsinga (A) | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Isaziso:
1. I-electrode kufuneka ibhakwe iyure e-1 malunga ne-300℃ ngaphambi kokuba isebenze nge-welding. Zama ukusebenzisa i-arc emfutshane uku-welding;
2. Kubalulekile ukucoca umhlwa, ioyile, amanzi kunye nokungcola kwiindawo zokuwelda ngaphambi kokuba uwelda.
3. Zama ukusebenzisa amandla amancinci xa udibanisa iintambo, usebenzisa iileya ezininzi kunye ne-multi-pass welding.
