1.Qhov hom vuam sib tw yog sib xws nrog kub - dip phau ntawv steel?
Kuj tseem ceeb chaw vuam: ib qho txuj ci vuam hauv kev lag luam thiab tsev neeg siv khoom lag luam (piv txwv li lub tsheb cev ntas thiab tshuab ntxhua khaub ncaws nruas). Los ntawm nce lub vuam tam sim no (10% {5% siab dua li cov hlau tawg, Tsis tas li ntawd, siv cov khoom siv hluav taws xob alloy (xws li chromium - zirconium-tooj liab) txo zinc corrosion thiab ua kom muaj kev ruaj ntseg weld ruaj khov.
Cov pa roj carbon dioxide (co₂) roj thaiv cov txheej txheem rau cov qauv steel thiab piv txwv, lub Hoobkas teeb thiab kev sib tham xov tooj). Silicon -} muaj cov hlau hlau (piv txwv li, er50- 6) yog siv. Silicon reacts nrog zinc vapor los ua ib qho qis {{9} melting-point silicate sag, uas floats rau weld nto thiab txo porosity. Thaum lub sij hawm vuam, tswj qhov kev ncua deb ntawm lub nozzle thiab qhov ua haujlwm (15-20 hli) los pab txhawb zinc vapor khiav tawm thiab txo weld tsis zoo.
Arc Vuam (phau ntawv vuam): Tsim nyog rau cov paib tuab (ntau dua los yog sib npaug rau 10 hli) lossis daim teb, cov yeeb nkab kev sib txuas). Xaiv cov pob zeb tso zis acidic (xws li J422), raws li lawv cov nplais pob muab cov kev pab them zoo heev thiab tuaj yeem tso cov npuas loj tsim los ntawm zinc vapor. Siv Arc luv luv thaum vuam kom txo qis cua sov ntau dhau ntawm zinc txheej thiab tsis txhob zinc hlawv.
Laser Vuam / Ntshav Vuam Welding: Haum rau high - Precision vuam cov ntawv thov thiab tshuab hluav taws xob sib xyaw). Cov no siv lub siab {2} h zog {}} Qhov chaw sov} Lub sijhawm kub nyob rau hauv qhov kub thiab txias. Qhov no txo qhov cuam tshuam ntawm zinc vapor ntawm weld tsim, uas ua rau du weld nrog qhov tseeb ntawm ± 0.05 hli.
2.Qhov yog qhov Weld lub zog ntawm kub - dip galvanized steel daim phiaj thaiv?
Guaranteed Strength: Under normal processing conditions, the tensile strength of the weld can reach over 90% of the base material strength (eg, Q235 hot-dip galvanized steel sheet, with a weld tensile strength of>=200 MPa), meeting the load-bearing requirements of industries such as construction and automotive. Piv txwv li, kub {{{{{- pa galvanized steel ntawv siv nyob rau hauv chaw loj vuam, thiab cov welds tuaj yeem tiv thaiv qhov kev sib tsoo tsheb tsis tau tawg.
Cov khoom muaj zog zoo heev: Qhov kev cuam tshuam nyuaj ntawm Weld thiab tshav kub}}} kev cuam tshuam rau cov khoom siv hluav taws xob tsawg dua (xws li cov tshuab hluav taws xob tsis zoo tsawg kub.
Kev qaug zog tsis kam: Raws li cov nqaj hlau tsis ua haujlwm (piv txwv li crane tseem muaj zog ntawm Weld yog qhov zoo ib yam li cov khoom siv hlau dog dig. Lub zinc txheej tsis muaj qhov cuam tshuam tsis zoo rau kev ua kom qaug zog ntawm Weld, thiab tsuas yog yuav tsum tau kho cov weld, thiab tsuas yog siv zinc pleev kev kho kom zoo (xws li ntev {4 4.
3.Txhua kev tswj kev tswj hwm vuam tsis xws luag?
Pority tswj: Ntxiv rau xaiv silicon {{0} Cov roj ntau dua li ntawm cov hlau ua ntej Qhov no tuaj yeem khaws Weld Porosity hauv qab 0.5%, deb hauv qab cov qauv kev lag luam ntawm 2%.
Splosion supression: thaum vuam, kho cov ntaub thaiv vuam (xws li CO₂ shielded vuam tam sim no uas yuav ua rau muaj kev sib txuas tam sim no. Ua ntawv thov ib tus neeg sawv cev tiv thaiv kab mob rau lub chaw ua haujlwm kuj tseem tuaj yeem txo cov phuav sab nrauv thiab tu kom huv tom ntej.
Zinc Slagal yog qhov yooj yim: Residual Zinc Slag Nws yuav tsis nkag rau hauv weld thiab cuam tshuam kev ua tau zoo.
4. Qhov zoo ntawm Weld tiv thaiv thiab kho tau yooj yim?
Zos zinc rov ua dua tshiab: ME NYE NYHAV (xws li cov khoom siv hauv cov khoom siv) tuaj yeem sib xyaw nrog txias {} tsuag tsuag xim (zinc cov ntsiab lus ntau dua los yog sib npaug rau 95%). Tom qab ziab, cov txheej zinc tuaj yeem ncav cuag ib txheej tuab ntawm 60}}}}}}}}}} dauv txheej galvanized. Cov ntawv loj loj (xws li cov neeg hauv cov qauv hlau) tuaj yeem kho nrog kub {}}} tsuag tsuag (nplaim taws {} txau zinc hlau). Qhov no zinc txheej muaj cov nplaum uas muaj zog thiab kev tiv thaiv kev tiv thaiv kev tiv thaiv lub neej sib piv sib piv rau qhov qub kub-dip galvanized txheej.
Yuav tsum muaj cov kev pab txheej txheej tag nrho Cov txheej no muaj cov khoom lag luam zoo dua (hla {}} Hatch 0) piv rau cov txheej txheem txias zoo tib yam, thiab txuas ntxiv mus ntxiv lub neej.
5.Qhov yog tus tub ntxhais ua haujlwm tseem ceeb ntawm vuam yoogam?
Weldability ntawm kub - dip galvanized steel ntawv yog qhov tseem ceeb ua ke ntawm cov kev ua ke zinc txheej thiab ruaj khov kev ua tau zoo. Kho cov txheej txheem vuam (cov ntaub ntawv tsis zoo, thiab cov khoom siv tsis zoo ntawm cov txheej txheem weldent ntawm cov khoom siv weld, kev nruj me ntsis.
