ISO 3581-A He kowiri tira A-ringa hiko nga taputapu Welding
Ka taea te whakamahi mo nga kaupapa AC me te DC, a he pai rawa atu te kapiti o te whakarewa.E tika ana mo nga waahi katoa, he pai te kaha o te kiri hiko.Ka whakamahia te nuinga mo te whakarewa i te rino ASTM307 me etahi atu maitai rereke, ka taea hoki te whakamahi mo te whakarewa i te papa o te rino aatete aa me te paparanga whakawhiti.Pērā i te maitai konupora teitei, te maitai whakapakeke, etc.
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 E5016, AWS A5.1 E7016 & A5.1M E4916, ISO2560-A: E 42 3 B 1 2, ISO 2560-B: E4916 A
Whakatupatotanga Welding:
I mua i te whakapiri, me tino kore te hinu, te waikura, te makuku, me etahi atu;whakamaroke i te 350°C mo te haora;me te whakamaroke me te whakamahi
3. Whakamahia te whaowhia haere kuiti me te whakahiato pewa poto;AC me DC hononga whakamuri.
Ka taea te whakamahi mo te whakapiri i te waro waro iti me te 490MPa te kaha teitei o te putorino putorino paipa hono, ka taea te mohio ki te hanga i te taha taha-rua.
Ko te electrode no te momo hauwai iti, putorino paipa me te hanganga whanui o te pakiaka o te weld, ka taea te mohio ki te whakakotahi i te taha kotahi ki te hanga i nga taha e rua, kia taea ai te whakaora i te rekereke horoi horoi, kia pai ake ai te pai o te whakapiri. .
Nga waahanga matua o te tukanga:
1, whakamaroke i mua i te whakamahinga, 300 ~ 350 ℃ whakamaroke 30 ~ 60 meneti;
2, whiriwhiri i te nāianei tika me te haehae, i roto i te tikanga ki te tiki i te fehokotaki'anga hoki ataahua;
3. Ka tineia te pewa, arahina te rua arc ki te taha o te riu, katahi ka pakaru te pewa;
4. Te wa timata arc ma te whakamahi i te pereti timata arc ranei i te taha o te pewa haehae;
5. Puritia poto fehokotaki'anga pewa;
6. Whakamahia te hononga whakamuri AC, DC ranei.
Ngā āhuatanga
1. Titanium calcium kowiri tira hiko, ko te hanganga matua ko 18% CR-8% Ni-6% Mn;
2. Arc u, ataahua hanga, ripples pai, he torutoru pōrutu, ngāwari de-slagging, ātete ahi pai o te kiri tarukino, pai ātete stomatal.
3. Ko nga taonga miihini pumau, he nui te tere o te whakawhiti hihi X.
E307-16with Grade (AWS A5.4),Stainless steel fehokotaki'anga Electrode he momo rereke o te whakarewa maitai pērā i te fehokotaki'anga austenitic konupora ki te whakarewa maitai waro whakarewa ranei.
Ka whakamahia nuitia i roto i nga umanga tono kanorau ka hangaia mai i te hangarau taone me te kounga teitei o nga rawa mata me nga ahuatanga hou, Ka taea hoki enei hiko hiko SS te hanga ritenga e pa ana ki o raatau rahi me te matotoru kia rite ki nga whakaritenga a nga kaihoko.
