Copper le Copper Alloy Welding Electrode
T207
GB/T ECuSi-B
AWS A5.6 ECuSi
Tlhaloso: T207 ke electrode ea koporo ea alloy e nang le mokokotlo oa boronse oa silicon le coating e tlaase ea hydrogen sodium.Sebelisa DCEP (electrode e nepahetseng ea hajoale) e nang le thepa e ntle ea mochini.E na le khanyetso e ntle ea kutu ho li-inorganic acid ntle le asiti ea nitric, boholo ba li-organic acid le metsi a leoatle.
Kopo: E loketse bakeng sa tjheseletsa ea koporo, boronse ba silicon le koporo, ho tjheseletsa ka holim'a masela a liphaephe tsa mechine ea lik'hemik'hale, joalo-joalo.
Sebopeho sa lik'hemik'hale tsa tšepe ea weld(%):
| Cu | Si | Mn | Pb | Al+Ni+Zn |
| hoo e ka bang 92.0 | 2.5 ~ 4.0 | ≤3.0 | ≤0.02 | ≤0.50 |
Mechine ea tšepe ea weld:
| 试验项目 Ntho ea teko | 抗拉强度 Matla a tšepe Mpa | 延伸率 Elongation % |
| 保证值 Guaranteed | ≥270 | ≥20 |
Nako e khothalelitsoeng:
| Bophara ba molamu (mm) | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 90-130 | 110 ~ 160 | 150 ~ 200 |
Tlhokomeliso:
Mehato ya tlhokomelo:
1. Electrode e tlameha ho behoa hoo e ka bang 300 ° C bakeng sa lihora tse 1 ho isa ho tse 2 pele ho tjheseletsa;
2. Mongobo, oli, oxides le litšila tse ling holim'a weldment e tlameha ho tlosoa pele ho cheselletsa.
3. Ha tjheseletsa silicon boronse kapa holim'a tjheseletsa holim'a tšepe, ha ho hlokahale preheating.Thempereichara preheating bakeng sa tjheseletsa koporo e hloekileng e ka bang 450 ° C, 'me mocheso preheating bakeng sa tjheseletsa koporo e ka bang 300 ° C;
4. Ho lokela ho sebelisoa welding e khutšoanyane ea arc nakong ea ho tjheseletsa.Nakong ea li-welding tse ngata, slag pakeng tsa lihlopha e tlameha ho ba
ho tlosoa ka ho feletseng;ka mor'a ho cheselletsa, etsa hamore ea weld ka hamore ea hlooho e bataletseng ho ntlafatsa lijo-thollo, ho felisa khatello ea kelello, le ho ntlafatsa matla le polasetiki ea weld.
