Vuam cov ntsiab lus thiab ceev faj rau stainless hlau cua electric rhaub

1, Kev npaj ua ntej vuam
1. Raws li cov khoom yuav tsum tau kos duab, tshem tawm cov hlau tsis sib xyaw txheej ntawm qhov sib koom ua ke siv cov txheej txheem ua haujlwm, thiab ua kom haum rau cov pob tw.
2. Ntxuav nyob rau hauv ib qhov dav ntawm 10-20 hli ntawm ob sab ntawm lub vuam seam, siv cov hlau txhuam los yog polishing txoj kev tshem tawm oxides, xeb, roj, noo noo, thiab lwm yam khoom uas cuam tshuam rau vuam zoo.
3. Sib sau ua ke raws li cov khoom kos duab thiab siv cov welding rods rau qhov chaw vuam ntawm cov pa roj carbon steel. Qhov chaw welding welder yuav tsum muaj daim ntawv pov thawj kev ua haujlwm siv tau los xyuas kom meej qhov zoo ntawm qhov chaw vuam. Qhov ntev ntawm qhov chaw vuam yog 25-30mm.
2, Vuam txheej txheem
1. Vuam txheej txheem rau pob qij txha ntawm stainless hlau puas steel daim hlau
1.1 Welding ntawm cov pa roj carbon steel
1.1.1 Txoj kev tsis siv neeg submerged arc vuam yog saws, nrog ib txheej welded rau pem hauv ntej sab. Tom qab tig dhau, sab nraub qaum yog thawj zaug ntxuav nrog carbon arc gouging txoj kev, thiab tom qab ntawd muab khi nrog ib txheej welded rau sab nraub qaum. Cov specifications ntawm welding yog raws li nram no:
Txoj hauj lwm Vuam Hlau Flux Vuam Hlau Diameter Arc Voltage Vuam Tam sim no Vuam Ceev
Pem hauv ntej H08A J431 φ 5mm 31-33V 500-550A 44-46 cm/min
Rov qab H08A J431 φ 5mm 32-34V 580-620A 44-46 cm/min
1.1.2 Ntxuav lub slag tom qab vuam thiab polish nws.
1.1.3 X-ray sampling soj ntsuam tom qab vuam, nrog rau qhov piv txwv ntawm 10-20 feem pua, lossis UT tshuaj xyuas
1.2 Hloov txheej txheej vuam
Siv CO2 semi-automatic gas shielded vuam txoj kev, weld ib txheej, thiab xaiv cov nram qab no vuam specifications:
Flux cored vuam hlau TS-309
Vuam hlau txoj kab uas hla φ1.2 (MM)
Arc voltage 19-21V
Vuam tam sim no 130-150A
1.3 Ntau txheej vuam
Siv CO2 semi-automatic gas shielded vuam txoj kev, weld ib txheej, thiab vuam specifications yog raws li nram no:
Flux cored vuam hlau TS-316L
Vuam hlau txoj kab uas hla φ1.2 (MM)
Interlayer kub 150 degree
