Ingxubevange yobhedu kunye neCopperUkuweldaI-Electrode
T107
GB/T ECu
AWS A5.6 ECu
Inkcazo: T107 i electrode yobhedu ecocekileyo kunye nobhedu olusulungekileyo njengondoqo kwaye igqunywe ngohlobo oluphantsi lwe-hydrogen sodium.Sebenzisa i-DCEP (i-electrode yangoku echanekileyo).Iipropathi ezilungileyo zoomatshini, ukumelana nokudumba okuhle emoyeni kunye namanzi olwandle, akufanelanga ukuwelda i-oksijini equlathe ubhedu kunye nobhedu lwe-electrolytic.
Isicelo: Isetyenziselwa ikakhulu ukuwelda amacandelo obhedu afana neentsimbi zobhedu eziqhutywayo, ii-copper exchangers zobushushu, kunye nemijelo yamanzi olwandle kwiinqanawa.Inokusetyenziselwa ukuwelda ngaphezulu kwentsimbi yekhabhoni ekwaziyo ukumelana nokudleka kwamanzi olwandle.
Ukwakhiwa kweekhemikhali zentsimbi edibeneyo(%):
| Cu | Si | Mn | P | Pb | Fe+Al+Ni+Zn |
| 95.0 | ≤0.5 | ≤3.0 | ≤0.30 | ≤0.02 | ≤0.50 |
Iimpawu zobuchwephesha bentsimbi ye-weld:
| Into yovavanyo | Tensile strength Mpa | Elongation % |
| Iqinisekisiwe | ≥170 | ≥20 |
yangoku eCetyisiweyo:
| Intonga yobubanzi (mm) | 3.2 | 4.0 | 5.0 |
| UkuweldaOkwangoku (A) | 120 ~ 140 | 150 ~ 170 | 180 ~ 200 |
Isaziso:
1. I-electrode kufuneka ibhakwe malunga ne-200 ° C ngeyure eli-1 ngaphambi kwe-welding, kwaye umswakama, ioli, i-oxides kunye nezinye izinto ezingcolileyo phezu kwe-weldment kufuneka zisuswe.
2. Ngenxa ye-thermal conductivity yobhedu, kunye nokushisa kwangaphambili komthi omele ukudityaniswa ngokuqhelekileyo kuphezulu kakhulu, ngokuqhelekileyo ngaphezu kwe-500 °C.Ubungakanani be-welding current kufuneka buhambelane nokushisa kwangaphambili kwesiseko sesinyithi;Zama ukuwelda kwi-arc emfutshane.Ingasetyenziselwa ukuphindaphinda isindululo somgca ukuphucula ukubunjwa kwe-weld.
3. Kwii-welds ezide, zama ukusebenzisa indlela ye-welding ye-back step, kwaye isantya se-welding kufuneka sikhawuleze kangangoko.
Xa i-welding multi-layer, i-slag phakathi kweengqimba kufuneka isuswe ngokupheleleyo;emva kwe-welding, nyula i-weld ngehamile yentloko ethe tyaba ukuze unciphise uxinzelelo,
Phucula umgangatho we-weld.
