I-Copper kunye ne-Copper Alloy Welding Electrode
T207
GB/T ECuSi-B
AWS A5.6 ECuSi
Inkcazo: I-T207 yi-electrode ye-alloy yobhedu kunye ne-silicon yobhedu yobhedu kunye ne-hydrogen sodium ephantsi yokwaleka.Sebenzisa i-DCEP (i-electrode echanekileyo yangoku) eneempawu ezinkulu zomatshini.Inokumelana ne-corrosion elungileyo kwi-asidi ye-inorganic ngaphandle kwe-asidi ye-nitric, uninzi lweeasidi eziphilayo kunye namanzi olwandle.
Isicelo: Ilungele ukuwelda ubhedu, ubhedu lwe-silicon kunye nobhedu, i-welding ye-surfacing ye-linings yemibhobho yoomatshini beekhemikhali, njl.
Ukwakhiwa kweekhemikhali zentsimbi edibeneyo(%):
| Cu | Si | Mn | Pb | Al+Ni+Zn |
| -92.0 | 2.5 ~ 4.0 | ≤3.0 | ≤0.02 | ≤0.50 |
Iimpawu zobuchwephesha bentsimbi ye-weld:
| 试验项目 Into yovavanyo | 抗拉强度 Tensile strength Mpa | 延伸率 Elongation % |
| 保证值 Iqinisekisiwe | ≥270 | ≥20 |
yangoku eCetyisiweyo:
| Intonga yobubanzi (mm) | 3.2 | 4.0 | 5.0 |
| I-Welding yangoku (A) | 90 ~ 130 | 110 ~ 160 | 150 ~ 200 |
Isaziso:
Ukulumkela:
1. I-electrode kufuneka ibhakwe malunga ne-300 ° C kwi-1 ukuya kwii-2 iiyure ngaphambi kwe-welding;
2. Umswakama, ioli, i-oxides kunye nezinye izinto ezingcolileyo ebusweni be-weldment kufuneka zisuswe ngaphambi kwe-welding.
3. Xa udibanisa i-silicon yobhedu okanye i-welding ye-surfacing kwintsimbi, akukho mfuneko yokufudumeza kwangaphambili.Iqondo lokushisa langaphambi kokushisa kwi-welding copper ecocekileyo li malunga ne-450 ° C, kunye nokushisa kwangaphambili kwi-welding brass malunga ne-300 ° C;
4. I-short-arc welding kufuneka isetyenziswe ngexesha le-welding.Ngexesha le-welding ye-multi-layer, i-slag phakathi kweengqimba kufuneka ibe
isuswe ngokupheleleyo;emva kwe-welding, nyula i-weld ngesando sentloko esicaba ukuze ucokise iinkozo, uphelise uxinzelelo, kwaye uphucule amandla kunye neplastiki ye-weld.
