Steel Structure Vuam Technology
Steel qauvwelding sequence thiab txheej txheem parameter ntawm cov pob qij txha raug:
(1) Lub earless phaj nyob rau sab sauv thiab qis yuav tsum raug txiav tawm los ntawm ob lub vuam thaum ob sab yog symmetrically welded rau 1/3 ntawm lub thickness ntawm lub phaj.
(2) Tom qab ntawd Ob tus neeg hlau yuav tsum tau welded symmetrically nyob rau sab ntawm lub pob ntseg txiav mus rau 1/3 ntawm lub thickness ntawm lub phaj.
(3) Ob lub vuam yuav tsum ua qhov vuam ntawm ob sab uas nyob ib sab.
(4) Cov pob qij txha ntawm qhov sib txuas ntawm txhua ob txheej yuav tsum tau staggered, thiab qhov sib koom ua ke ntawm txoj hlua vuam los ntawm ob lub vuam yuav tsum tau staggered txhua txheej, thiab qhov kub ntawm cov txheej yuav tsum raug kuaj xyuas thaum lub sij hawm vuam txheej txheem.
(5) Steel qauv vuam txheej txheem txheej txheem tsis:
CO2 roj tiv thaiv vuam: hlau txoj kab uas hla Φ1.2mm, tam sim no 280 ~ 320A, vuam ceev 350 ~ 450mm / min
Qhov ntev ntawm vuam hlau: li 20 hli, roj ntws 25 ~ 80L / min, qhov hluav taws xob yog 29 ~ 34V, thiab qhov kub nruab nrab yog 120 ~ 150 degree
Steel qauv welding tshuab: kem - beam, beam - beam sib koom
(1) Weld qis flange ntawm lub nqaj ua ntej, thiab flange welds ntawm ob sab ntawm lub vev xaib yuav tsum tau welded symmetrically.
(2) Tom qab lub flange qis yog welded, weld lub sab flange.
(3) Yog hais tias lub thickness ntawm lub flange phaj yog ntau tshaj 30 hli, lub sab sauv thiab sab flange yuav tsum tau welded alternately.
(4) Vuam parameter:
CO2 roj shielded vuam:
Txoj kab uas hla ntawm vuam hlau: φ1.2mm
Cov hluav taws xob tam sim no: 280 ~ 360A
Vuam ceev: 300 ~ 500mm / min
Qhov ntev ntawm cov vuam hlau yog li 20 hli
Gas ntws tus nqi: 20 ~ 80L / mm
Lub hwj chim: 30 ~ 38V
Interpass kub: 120 ~ 150 degree
