1. ukuhlukaniswa
Ngokwenani lokuqukethwe kwekhabhoni, i-carbon steel ingahlukaniswa ngezigaba ezintathu ezilandelayo:
1) Insimbi ye-carbon ephansi C% ≤ 0.25
2) Medium carbon steel 0.25
3) I-carbon steel ephezulu C% > 0.6
Ikhathoni eliphansi
Mid-Carbon
Ikhabhoni ephezulu
2. ukuhlaziywa kokushisela
Inani lokuqukethwe kwekhabhoni liyisithenjwa esibalulekile sokuthuthukiswa kwezinqubo zokushisela. Njengoba okuqukethwe kwekhabhoni kwanda, amandla nobulukhuni buyanda, kuyilapho ipulasitiki nokuqina kuncipha, kuyilapho ukucindezeleka kwanda. Uma sikhuluma ngokuqhathanisa, ukuncipha kwekhabhoni okuqukethwe, kuba ngcono ukushisela, ngakho-ke, okuqukethwe kwekhabhoni kuyindinganiso yokwahlulela ubunzima be-carbon steel welding, futhi izinqubo zokushisela ezihlukene kufanele zamukelwe kokuqukethwe kwekhabhoni okuhlukile.
3. Inqubo yokushisela
Ukukhethwa kwe-carbon steel welding materials kulandela isimiso "samandla alinganayo"
1. Insimbi ye-carbon ephansi (evame ukwaziwa njengensimbi emnene)
Amamaki ensimbi avamile afana ne-Q235 (eyayivame ukubizwa ngokuthi i-A3 steel), i-Q255, njll., ngokuvamile awathathi izinyathelo ezikhethekile lapho kushiselwa, kungashisi kuqala noma kudlule ukushisa.
2. Insimbi ye-carbon ephakathi
Insimbi evame ukusetshenziswa njenge-30 #, 45 #, njll., 45 # iyimpahla yokukhiqiza ama-saw blades namafayela, kungcono kakhulu ukusebenzisa izinto zokushisela eziphansi ze-hydrogen ezinokumelana nokuqhekeka okuhle, ukushisa kuqala i-100-200 ° C; Uma kungafaneleki ukushisa kuqala, kungakhethwa impahla yokushisela yensimbi engenasici ye-Cr-Ni austenitic.
3. High carbon steel
Amamaki ensimbi asetshenziswa kakhulu njenge-60Si2Mn, T8, T10 njalonjalo. I-60Si2Mn iyinsimbi evamile yasentwasahlobo, ngokuvamile ayikwenzi ukwelashwa kwe-welding, esetshenziswa kakhulu njenge-welding kabusha, kufanele ibe ngu-250-350 ° C preheating, i-welding kumele igaywe ngesando ukuze kuqedwe ukucindezeleka, kanye nokwelashwa kwangemva kokushisa okungama-650 ° C, nakho kungakwazi. khetha Cr-Ni austenitic insimbi engagqwali welding materials
Okwesine, izinto ezibalulekile zokushisela i-electrode yesandla sensimbi emnene:
Izinga lokushisa lokumisa i-Electrode
| Into | Uhlobo lwesikhumba | Umkhiqizo | Izinga lokushisa | Isikhathi |
| Insimbi ye-carbon ephansi nensimbi enamandla amakhulu | Uhlobo lwe-hydrogen oluphansi | I-E7016, E7048, E7015, E7015-G | 300-350 ℃ | 60 imiz |
| I-E7015, E8015-G, E9016-G, E9015-D1, E10015-D2, E12015-G | 330-380 ℃ | |||
| Ukuqina okuphezulu kanye nohlobo oluphansi lwe-hydrogen | E7016-G,E7015-G,E8015-G,E9015-G,E10015-G | 350-380 ℃ | 60 imiz | |
| I-iron powder uhlobo oluphansi lwe-hydrogen | I-E7018, E7018-1 | 300-350 ℃ | 60 imiz | |
| E8018-G,E918-G,E9018-M,E10018-D2,E10018M,E11018-G,E11018M,E12018-G | 350-380 ℃ | 60 imiz |
2. Umswakama, amafutha, ukugqwala, njll ebusweni bezinto eziyisisekelo kufanele kususwe
3. Sebenzisa indlela eya phambili ukushisela ukugwema i-stomata lapho uqala khona
I-arc welding emfushane kufanele isetshenziswe, njengemicu ye-oscillating, futhi i-oscillation amplitude akufanele idlule izikhathi ezi-3 ububanzi bezintambo.
