Iti Alloy Steel Welding Hiko
J707
GB/T E7015-D2
AWS E10015-D2
Whakaahuatanga: Ko te J707 he hiko hiko teitei teitei me te paninga konutai iti-waikawa.Whakamahia te DCEP (te hiko hiko tika o naianei), ka taea te paihere ki nga waahi katoa.I te wa e tika ana, ka taea te whakamahana i nga weldments i mua i te whakapiri me te whakamaarama i muri i te whakapiri.
Taupānga: Te nuinga whakamahia mō te fehokotaki'anga 15MnMoV, 14MnMoVB, 18MnMoNb me ētahi atu hanganga rino-iti.Ka taea e te hanganga paiherea te mahi i raro i te ahua o te weriweri, te whakamahana ranei (500 ~ 650 ℃).
Te hanganga matū o te whakarewa whakarewa(%):
| C | Mn | Si | Mo | S | P |
Ka whakamanahia | ≤0.15 | 1.65 ~ 2.00 | ≤0.60 | 0.25 ~ 0.45 | ≤0.035 | ≤0.040 |

O nāianei e taunaki ana:
(mm) Te diameter o te tokotoko | 2.5 | 3.2 | 4.0 | 5.0 |
(A) Waeherehere o naianei | 60 ~ 100 | 100 ~ 140 | 140 ~ 190 | 190 ~ 250 |
Panui:
1. Me tunuhia te electrode mo te 1 haora i te 350 ~ 380 ℃ i mua i te mahi whakapiri;
2. He mea nui ki te horoi i te waikura, te unahi hinu, te wai, me nga poke i runga i nga waahanga whakapiri i mua i te whakapiri;
3. Whakamahia te mahi arc poto ina whakapiri.He tika te ara fehokotaki'anga kuiti.
