490Mpa Hiko Ringa Mo Te Tino Kaha Rawa
Taupānga&Paerewa
1.He pai mo te WELDING OF CARBON STEEL ME TE KAUPAPA KAUPAPA KAUPAPA, ME TE kaha o te paera, te paipa, te oko pehanga, te hangahanga o te hanga miihini moana, penei i te Q345, X60 pipeline maitai, etc.
2. Ko te paerewa i tutakihia e matou: GB / T5117 E5015-G AP, AWS A5.5 E7015-G & A5.5M E4915-G, ISO2560-A:E 42 4 Z0.5 Ni B 2 2, ISO 2560-B: E4915 G-AP
Nga tohu hei aro:
1. I mua i te whakapiri, me tunuhia te electrode i te 350 ℃ mo te 1 haora ka tangohia ina hiahiatia.
2. I mua i te whakapiri, me horoi te weldment i te waikura, te hinu, te wai me etahi atu poke.
3. Me mahi te welding ki te pewa poto, he tika te whaowhiowhio.
Ngā āhuatanga
1. He iti te hiko konupora hauwai, he pewa pumau, he ataahua te hanga, he ataahua, he iti te pakaru, he ngawari te whakakore, he pai te kiri o te ahi, he pai te porosity.
2. nga taonga miihini tepu, te kirihou pai, te pakari o te paanga me te aukati kapiti.He iti te ihirangi hauwai marara.
J507RH rite ki GBE5015-G. Te kaha tensile 500 ~ 600MPa kaha tuku 420 ~ 450MPa pānga ki 40 nekehanga taea tae 100 ~ 120JRH he hauwai ultra-iti hiko uaua teitei. 1. Ka tunuhia te hiko o mua ki te 350-430 ℃ mo te 1h, ka tukuna ki roto i te incubator i te 100-150 ℃ mo te whakamahi ki te tunu. 2. I mua i te whakapiri, ka horoia te weldment i te waikura, te hinu, te wai me etahi atu poke. 3. Me whakamahi te pewa poto i te wa o te whakapiri, a he tika te huarahi weld kuiti.
