Te Hiko Te Whakamahana Te Maamaa Te Hiko
W707
GB/T E5015-G
AWS A5.5 E7015-G
Whakaahuatanga: Ko te W707 he hiko hiko iti-mahana me te paninga konutai iti-waiwai.Whakamahia te DCEP (te hiko tika o naianei) ka taea te paihere ki nga waahi katoa.He pai tonu te pakaritanga o te konganuku kua whakatakotoria ki te -70°C.
Taupānga: Whakamahia mō te fehokotaki'anga maitai pāmahana iti pērā i 2.5Ni.
Te hanganga matū o te whakarewa whakarewa(%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Nga ahuatanga miihini o te whakarewa whakarewa:
| Tuemi whakamatautau | Te kaha tensile Mpa | Te kaha tuku Mpa | Te whakaroa % | Uara pānga (J) -70 ℃ |
| Ka whakamanahia | ≥490 | ≥390 | ≥22 | ≥27 |
Ko te ihirangi hauwai whakamaoritanga o te konganuku kua penapena: ≤6.0mL/100g (tikanga glycerin) ranei ≤10mL/100g (tikanga chromatography hau ranei)
Tirohanga X-ray: Ko taku tohu
O nāianei e taunaki ana:
| （mm） Te diameter o te tokotoko | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| （A） Waeherehere o naianei | 40 ~ 70 | 70 ~ 100 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Panui:
1. Me tunuhia te electrode mo te 1 haora i te 350 ℃ i mua i te mahi whakapiri;
2. Whakamātauria ki te whakamahi i te pūngao raina iti ina fehokotaki'anga, maha-apa me te maha-haere fehokotaki'anga.
