Nickel and Nickel Alloy Welding Electrode
Ni307-2
GB/T ENi6133
AWS A5.11ENiCrFe-2
Whakaahuatanga: Ko te Ni307-2 he electrode i runga i te nickel me te paninga konutai iti-hydrogen.Whakamahia te DCEP (te hiko tika o naianei pai).I te mea he nui te molybdenum, te niobium me etahi atu mea whakauru i roto i te weld, he pai te aukati kapiti o te whakarewa.
Taupānga: Ka whakamahia mo te whakapiri i nga koranu nickel-chromium-rino (penei i te UNS N08800, UNS N06600), he pai rawa atu mo te whakapiri i nga konganuku rereke, te whakapiri paparanga whakawhiti me te whakakii i te papa, ka taea hoki te whakamahi ina ko te 980 ° C te pāmahana mahi, engari ka taea e ia te aukati i te waikura ina teitei ake te pāmahana i te 820 ° C Te heke o te ira tangata me te kaha.
Te hanganga matū o te whakarewa whakarewa(%):
| C | Mn | Fe | Si | Cu | Ni |
| ≤0.10 | 1.0 ~ 3.5 | ≤12.0 | ≤0.8 | ≤0.5 | ≥62.0 |
| Cr | Nb + Ta | Mo | S | P | Ētahi atu |
| 13.0 ~ 17.0 | 0.5 ~ 3.0 | 0.5 ~ 2.5 | ≤0.015 | ≤0.020 | ≤0.50 |
Nga ahuatanga miihini o te whakarewa whakarewa:
| Tuemi whakamatautau | Te kaha tensile Mpa | Te kaha tuku Mpa | Te whakaroa % |
| Ka whakamanahia | ≥550 | ≥360 | ≥27 |
O nāianei e taunaki ana:
| Te diameter o te tokotoko （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Waehere naianei （A） | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Panui:
1. Me tunuhia te electrode mo te 1 haora i te taha o te 300 ℃ i mua i te mahi fehokotaki'anga;
2. He mea nui ki te horoi i te waikura, te hinu, te wai, me nga poke i runga i nga waahanga whakapiri i mua i te whakapiri.Ngana ki te whakamahi i te pewa poto ki te wea.
