Kowiri tira fehokotaki'angaHikohiko
A902
GB/T E320-16
AWS A5.4 E320-16
Whakaahuatanga: Ko te A902 he hiko kowiri tira me te paninga titanium-calcium.Ka taea te whakamahi mo te AC me te DC me te mahi tino pai.He tino pai te parenga waikura me te kaha o te waikura i roto i te hanga o te ahumahi matū, te hinu, me te hauwai.
Taupānga: Whakamahia mō te fehokotaki'anga o Carpenter20Cb nickel koranu i roto i te waikawa pungatara, waikawa nitric, waikawa ūkuikui me te waikura waikawa waikura reo.Ka taea hoki te whakamahi mo te whakarewa maitai rereke.
Te hanganga matū o te whakarewa whakarewa(%):
| C | Si | Mn | Cr | Ni | Mo | Cu | Nb | S | P |
| ≤0.07 | ≤0.60 | 0.5 ~ 2.5 | 19.0 ~ 21.0 | 32.0 ~ 36.0 | 2.0 ~ 3.0 | 3.0 ~ 4.0 | 8 XC ~ 1.00 | ≤0.030 | ≤0.030 |
Nga ahuatanga miihini o te whakarewa whakarewa:
| Tuemi whakamatautau | Te kaha tensile Mpa | Te whakaroa % |
| Ka whakamanahia | ≥550 | ≥30 |
O nāianei e taunaki ana:
| Te diameter o te tokotoko （mm） | 2.5 | 3.2 | 4.0 |
| Waeherehere o naianei （A） | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 |
Panui:
- Me tunu te electrode mo te 1 haora i te 150 ℃ i mua i te mahi fehokotaki'anga;
- Na te mea he papaku te hohonutanga o te urunga i te wa e whakahiato ana i te AC, me whakamahi te mana hiko DC kia kaha ake ai te kuhu.kia kaua hoki e nui rawa te au ki te karo i te whero o te rakau whakapiri.
Wenzhou Tianyu Electronic Co., Ltd. i whakapumautia i te tau 2000. Kua mahi matou ki te hanga ote hiko hikos, tokotoko fehokotaki'anga, apau i te fehokotaki'anganeke atu i te 20 tau.
