I-Copper kunye ne-Copper AlloyUkuweldaI-electrode
T107
I-GB/T ECu
I-AWS A5.6 ECu
Inkcazo: I-T107 yi-electrode yobhedu olucocekileyo olunobhedu olucocekileyo njengombindi kwaye lugqunywe yi-sodium type flux ephantsi kwe-hydrogen. Sebenzisa i-DCEP (i-electrode yangoku ngqo echanekileyo). Iipropati ezilungileyo zoomatshini, ukumelana okuhle nokugqwala emoyeni nasemanzini olwandle, ayifanelekanga ukuwelda i-copper equlethe i-oxygen kunye ne-electrolytic copper.
Ukusetyenziswa: Isetyenziswa kakhulu ekudibaniseni izinto zobhedu ezifana neebhari zobhedu eziqhubayo, izitshintshi zobushushu zobhedu, kunye nemijelo yamanzi olwandle yeenqanawa. Ingasetyenziselwa ukunxibelelanisa iindawo zentsimbi yekhabhoni ezimelana nokugqwala kwamanzi olwandle.
Ukwakheka kweekhemikhali zesinyithi esijiyiweyo (%):
| Cu | Si | Mn | P | Pb | Fe+Al+Ni+Zn |
| ＞95.0 | ≤0.5 | ≤3.0 | ≤0.30 | ≤0.02 | ≤0.50 |
Iimpawu zoomatshini zesinyithi esijijekileyo:
| Into yovavanyo | Tensile strength I-Mpa | Ukwandiswa % |
| Iqinisekisiwe | ≥170 | ≥20 |
I-current ecetyiswayo:
| Ububanzi bentonga （mm） | 3.2 | 4.0 | 5.0 |
| UkuweldaOkwangoku (A) | 120 ~ 140 | 150 ~ 170 | 180 ~ 200 |
Isaziso:
1. I-electrode kufuneka ibhakwe malunga nama-200°C kangangeyure e-1 ngaphambi kokuba i-welded, kwaye umswakama, ioyile, ii-oxides kunye nezinye izinto ezingcolileyo ezikumphezulu we-weldment mazisuswe.
2. Ngenxa yokuqhuba kobushushu kobhedu, kwaye ubushushu bokufudumeza iinkuni eziza kudityaniswa buhlala buphezulu, buhlala bungaphezulu kwama-500 °C. Ubukhulu bomsinga wokuwelda kufuneka buhambelane nobushushu bokufudumeza kwangaphambili besinyithi esisisiseko; Zama ukuwelda okuthe nkqo okumfutshane kwe-arc. Ingasetyenziselwa ukujikeleza intshukumo yomgca ukuphucula ukwakheka kwe-weld.
3. Kwi-welds ezinde, zama ukusebenzisa indlela ye-back step welding, kwaye isantya se-welding kufuneka sikhawuleze kangangoko.
Xa kudityaniswa iileya ezininzi, i-slag phakathi kweeleya kufuneka isuswe ngokupheleleyo; emva kokudityaniswa, faka i-weld ngesando esithe tyaba ukuze unciphise uxinzelelo,
Phucula umgangatho wokuwelda.
