Umuringa n'umuringa Alloy Welding Electrode
T207
GB / T ECuSi-B
AWS A5.6 ECuSi
Ibisobanuro: T207 ni electrode y'umuringa hamwe na silicon bronze ya bronze hamwe na sodium ya hydrogène nkeya.Koresha DCEP (itaziguye ya electrode nziza) hamwe nibikoresho bikomeye bya mashini.Ifite ruswa irwanya aside irike itari acide ya nitric, aside nyinshi kama ninyanja.
Gushyira mu bikorwa: Birakwiriye gusudira umuringa, umuringa wa silikoni n'umuringa, gusudira hejuru y'imirongo y'imashini zikoresha imiti, n'ibindi.
Ibigize imiti yicyuma (%):
| Cu | Si | Mn | Pb | Al + Ni + Zn |
| ＞ 92.0 | 2.5 ~ 4.0 | ≤3.0 | ≤0.02 | ≤0.50 |
Ibikoresho bya tekinike yicyuma gisudira:
| 试验 项目 Ikizamini | 抗拉强度 Imbaraga Mpa | 延伸 率 Kurambura % |
| 保证 值 Bijejwe | 70270 | ≥20 |
Icyifuzo kigezweho:
| Diameter （Mm） | 3.2 | 4.0 | 5.0 |
| Kuzenguruka A） | 90 ~ 130 | 110 ~ 160 | 150 ~ 200 |
Icyitonderwa:
Icyitonderwa:
1. Electrode igomba gutekwa nka 300 ° C mumasaha 1 kugeza 2 mbere yo gusudira;
2. Ubushuhe, amavuta, okiside nindi myanda hejuru yubudodo bigomba kuvaho mbere yo gusudira.
3. Iyo gusudira umuringa wa silicon cyangwa kugaragara gusudira ku byuma, nta bushyuhe bukenewe.Ubushyuhe bwo gushyushya umuringa usukuye ni nka 450 ° C, n'ubushyuhe bwo gushyushya imiringa ni 300 ° C;
4. Gusudira bigufi-arc bigomba gukoreshwa mugihe cyo gusudira.Mugihe cyo gusudira-ibice byinshi, icyapa kiri hagati yabyo kigomba kuba
yakuweho burundu;nyuma yo gusudira, inyundo isudira hamwe ninyundo yo mumutwe kugirango itunganyirize ibinyampeke, ikureho imihangayiko, kandi wongere imbaraga na plastike ya weld.
