490Mpa Hiko Ringa Mo Te Tino Kaha Rawa
Taupānga&Paerewa&Tuhipoka:
1. He pai mo te WELDING OF CARBON STEEL ME TE KAUPAPA KAUPAPA KAUPAPA, ME TE KAUPAPA KAUPAPA O TE BOILER, te paipa, te waka, te whare, te piriti me etahi atu hanganga, penei Q345.
2. Ko te paerewa i tutakihia e matou: GB/T5117 E501, AWS A5.1 E701 & A5.1M E491, ISO2560-A:E 42 3 B 2 2, ISO 2560-B: E4915 A
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.
GEL-57 iti waro waro hiko hiko ringa, kōeke ao ko E7015, China kōeke ko J507, no ki te iti hauwai konutai kawakore electrode, e tika ana mo te fehokotaki'anga Q345 kaha kōeke o iti koranu maitai hanganga.Ko te J te reta tuatahi o te hononga maitai o te hanganga, e tohu ana mo te hiko hiko.He rite, nui ake ranei i te 490MPa (50 KGF/mm2) te kaha tensile o te whakarewa whakarewa 50.He iti te konutai hauwai hiko.Ko te electrode kei te raina me te tauira E5015, kei reira a E te tohu i te hiko me te kaha tensile o te 50 whakarewa whakarewa rite ki te nui atu ranei i te 490MPa (50 KGF/mm2).Ko te 1 e whakaatu ana i nga hiko hiko o te tuunga-katoa (te whakapiri papaa, te raima poutū, te whakapae whakapae, te whakapiri poutū).He iti te konutai hauwai hiko.Karekau he kaiwhakamau arc i roto i te electrode ka taea anake te whakamahi mo te whakapiri polarity whakamuri DC.
