1.} Yuav ua li cas Zinc Txheej Txheej Txheem cuam tshuam rau cov vuam zoo ntawm Secvanized ntawv?
Zinc evaporation thiab cov pa luam yeeb: zinc evaporates tsaus nti ntawm siab vuam, uas ua kom muaj ntau tus nqi zinc oxide (zno) pa taws tom qab txias {}}
Cuam tshuam: ua rau cov pas dej tsis khov, ntau zog, Weld Porosity khaws (zinc Vapor ceev cia), thiab thaiv kom muaj arc / laser .
Detherating qhov xwm txheej: Cov lus qhia tshav sov ntau dhau, cov hluav taws xob tsis txaus, thiab qhov cua tsis zoo, .
Kua zinc infiltration thiab embrittlement: molten zinc nkag mus rau hauv weld lossis tshav kub-cuam tshuam rau cov hlau emble) .
Kev cuam tshuam: Microcracks yog tsim nyob rau hauv weld lossis tshav kub-cuam tshuam cov kev ntxhov siab) .
Passivation zaj duab xis nyob seem: chromate passivation zaj duab xis (muaj cr⁶⁺ lossis cr³⁺) muaj kev ua tsis zoo thiab nyuaj kiag li tshem tawm .
Kev Cuam Tshuam: Kev sib chwv tau ntau zuj zus thaum lub sij hawm tiv thaiv vuam, ua rau muaj lub zog tsis ruaj khov hauv kev pib ntawm cov theem vuam; tej zaum yuav paug lub pas dej molten .
2. Kev xaiv cov khoom thiab khoom siv thiab khoom siv khoom siv twg cuam tshuam secc vuam zoo?
Vuam hlau / Electrode xaiv: Arc vuam hlau: VUAM HLAU MUAJ SI thiab AL (xws li Pas Dej Molten thiab Txo Cov Pores.
Cov Khoom Siv Hluav Taws Xob: Chromium Zirconium Tooj Liab Electrode rau Zinc corrosion dua li ntshiab tooj liab {}}}
Galvanized txheej tuab tuab thiab kev sib txuam: cov tuab tuab: Cov tuab tuab
Tsis ncaj zinc txheej ua rau sib txawv hauv cov kev sib chwv ze, cuam tshuam nrog kev sib xws ntawm welds .
Nto huv si: Roj thiab Plua Plav Ua Kom Txoj Kev Mob Siab Tshaj Plaws Ntawm Qhov Pores Thiab Nthuav Tawm, thiab De degreing thiab Kev Tu Kom Ua Ntej Vuam .
3. Qhov ib puag ncig ua li cas ib puag ncig ua rau SECc tau vuam zoo?
Qhov cua ua pa: yuam kom tso cov kab ke: yuav tsum tau! Inhalation ntawm zinc fume (zinc oxide) ua rau "hlau fume tshav kub" thiab paug cov khoom .
Workpiece sib dhos raug: Ntau qhov sib txawv ua rau lub pas dej molenCen) {} Kev ua haujlwm ruaj khov rau hauv lub tshav kub (chaw ua haujlwm
{{0 {}} Dab tsi yog cov ua rau vuam tsis xws luag?
Sib txig: Zinc Vinc Vapor tawg, tam sim no / siab Mismatch, electrode adhesion .
Porosity: Zinc Vapor Stagnation nyob rau hauv lub pas dej molten, tsis txaus tiv thaiv roj, siv vuam ceev {}}
Tawg: zinc infiltration rau hauv cov ciaj ciam av, siab kev ntxhov siab, qeeb txias tus nqi .
Tsis tiav fusion / me weld nugget: tsis txaus tam sim no, dhau los ua ntej, dhau electrode siab .
Cov Khoom Siv Hluav Taws Xob: Cov Khoom Uas Tsis Raug, Tsis Txaus Sib Tsoo, Kev Ua Siab Tsis Muaj Siab A6}}}
Ntxig weld nto: zinc vapor floats rau weld deg (ib txwm nyob rau hauv laser vuam / arc vuam) .
5. Dab tsi yog qhov ntsuas kom zoo rau kev txhim kho vuam zoo?
Kuj tseem ua hluav taws xob: Lub sijhawm luv + lub sijhawm luv + loj kawg + loj kawg chirconium tooj liab electrode + Tsis siv neeg sib tsoo tshuab {}}
Arc Vuam: Kev Hloov Tsheb Luv Luv + Tom Ntej Tilting Relding + AR / C -₂ Sib xyaw Groamerers {}}
Laser Vuam: Tshwj xeeb gap + ob sab roj av tiv thaiv + lub zog siab ceev ceev {}}
Kev Xav Tau Ntawm Dav: Kev tu nruj ua ntej vuam, yuam kev dim pa, thiab xaiv cov ntaub ntawv vuam tshwj xeeb {}}
