I-Copper ne-Copper Alloy Welding Electrode
T207
GB/T ECuSi-B
AWS A5.6 ECuSi
Incazelo: I-T207 iyi-electrode ye-alloy yethusi ene-silicon bronze core kanye ne-hydrogen sodium coating ephansi.Sebenzisa i-DCEP (i-electrode eqondile yamanje eqondile) enezakhiwo ezinhle zokusebenza.Inokumelana nokugqwala okuhle kuma-asidi angaphili ngaphandle kwe-nitric acid, ama-asidi amaningi aphilayo namanzi olwandle.
Isicelo: Ilungele ukushiselwa kwethusi, ithusi le-silicon nethusi, i-welding ye-linings yamapayipi emishini yamakhemikhali, njll.
Ukwakheka kwamakhemikhali ensimbi ye-weld(%):
Cu | Si | Mn | Pb | I-Al+Ni+Zn |
92.0 | 2.5 ~ 4.0 | ≤3.0 | ≤0.02 | ≤0.50 |
Izici zemishini ye-weld metal:
试验项目 Into yokuhlola | 抗拉强度 Amandla aqinile Mpa | 延伸率 Ukwelula % |
保证值 Kuqinisekisiwe | ≥270 | ≥20 |
Okwamanje okunconyiwe:
Ububanzi benduku (mm) | 3.2 | 4.0 | 5.0 |
I-Welding Yamanje (A) | 90 ~ 130 | 110 ~ 160 | 150 ~ 200 |
Isaziso:
Izinyathelo zokuzivikela:
1. I-electrode kufanele ibhakwe cishe ku-300 ° C amahora angu-1 kuya kwangu-2 ngaphambi kokushisela;
2. Umswakama, amafutha, ama-oxides nokunye ukungcola ebusweni be-weldment kumele kususwe ngaphambi kokushisela.
3. Uma ushisela ithusi le-silicon noma i-welding ebekwe phezu kwensimbi, akukho ukushisa kwangaphambili okudingekayo.Izinga lokushisa langaphambi kokushisa lokushisela ithusi elihlanzekile lingaba ngu-450 ° C, futhi izinga lokushisa langaphambi kokushisa kwethusi lokushisela lingaba ngu-300 ° C;
4. I-short-arc welding kufanele isetshenziswe ngesikhathi sokushisela.Ngesikhathi se-welding ye-multi-layer, i-slag phakathi kwezingqimba kufanele ibe
isuswe ngokuphelele;ngemuva kokushisela, shaya i-weld ngesando sekhanda eliyisicaba ukuze ucwenge okusanhlamvu, uqede ukucindezeleka, futhi uthuthukise amandla kanye ne-plasticity ye-weld.
