1.What yog lub luag haujlwm ntawm zinc cov ntsiab lus ntawm weld tsis xws luag?
Kev Tsim Kom Zoo
Txhim Kho Ci
Tsim kev tsim
Fe-ZN intermetallic tebchaw: tsim ntawm ζ theem (fezn₁₃) thiab Δ theem (fezn₇) ntawm qhov kub
When zinc content is >80g/m², the thickness of brittle phase in heat affected zone (HAZ) is >5μm
2.Qhov dab tsi yog zinc cov ntsiab lus tsis pub txwv rau cov txheej txheem vuam sib txawv?
Laser Vuam
Qhov Zoo: Tsawg tshav kub lub tswv yim → 50% txo cov zinc Volatilization
Zinc Cov Ntsiab Lus Qhov rai: GI Galvanized Sheet (Zinc Txheej 60-80g / M²): Weldable
ZM Txheej (Zinc Txheej 100-150G / M²): 0.2 hli sib txawv yuav tsum tau tshwj tseg rau kev kub siab
3.Qhov dab tsi yog zinc cov ntsiab lus ntxiv cov kev daws teeb meem?
Tsawg Zinc Txheej
Cov txheej txheem muaj feem xyuam: tag nrho cov arc vuam, laser vuam
Vuam Parameter Optimization: Ua kom Arc Voltage 2-3V (txuas ntxiv lub sijhawm ntawm Molten los pab Zinc Translatilization)
Siv hom ob chav mem tes (tsawg heev mem tes los huv zinc vapor)
Nruab Nrab rau Kev Kub Siab Zinc Txheej
Pority tswj: Laser-Arc Hybrid Vuam
Nta supression: actatorator
Kev hnav hauv elecroadode: Dispersed Tooj Liab Electrode
Ultra-siab Zinc Txheej
Yuav tsum muaj kev ntsuas: Laser tu ua ntej vuam (tshem zinc txheej hauv weld cheeb tsam, dav> 5mm)
Siv Hloov Hlau Hlau (CMT) thev naus laus zis (txo cov lus tawm los ntawm 40%)
Sau nrog lub ntiaj teb tsis tshua muaj hluav taws xob (LA / Y rov qab cov nplej thiab neutralizes zn brittleness)
4.Qhov xaiv cov khoom sib txawv rau cov ntawv thov muaj kev lag luam?
Lub Cev Vuam
Cov Txheej Txheem Xaiv: Sab saum toj Npog / Sab Vaj Huam Sib Luag: Laser Vuam (Sib Txawv Vuam (Sib Ntaus 0.1 hli)
CHASSIS Cov Qauv: Pulse mag
Kev Sib Kis Ntauwd
Cov kauj ruam tseem ceeb: nplaim taws preheating (200℃kom qeeb zinc volatilization)
Siv E6010 Vuam Qws (Cellulose Hom, Muaj Zog Arc Tshuab Yuam Kev)
Tsev neeg lub phaj nyias nyias daim hlau
Kev daws teeb meem siab: Kuj yog chaw chaw vuam + hauv zos passivation kev kho ntawm txheej
5.Qhov dab tsi yog qhov tseem ceeb ntawm zinc cov ntsiab lus ntawm Weldability?
Tsawg Zinc Txheej (<70G / M²): Kho Ac cov tsis muaj thiab Weld ncaj qha
Nruab Nrab rau Cov Txheej Zinc Zinc (80-150G / M²): Laser-Arc Hybrid Vuam + Awarator
Ultra-High Zinc Txheej (> 150g / M²): Laser Tu + Cmt + Tsawg Lub Ntiaj Teb Vuam Hlau
