Copper Hlau End Cap Resistance Brazing Cheebtsam Rau Fuse

Dab tsi yog qhov sib txawv ntawm kev siv vuam thiab kev tiv thaiv brazing rau Fuse Contact Cap?

Yuav ua li cas tom qab vuam tu rau kev tiv thaiv brazing?

Resistance welding ntawm Fuse Contact Cap yog hais txog ib txoj kev siv hluav taws xob tam sim no los ntawm kev siv vuam thiab cov hluav taws xob tiv thaiv hluav taws xob los ntawm kev sib cuag raws li qhov chaw tshav kub kom sov hauv qhov chaw vuam, thiab tib lub sij hawm pressurize txoj kev vuam. Thaum welding Fuse Contact Riam Cap, tsis tas yuav tsum tau muab tub lim hlau, kev tsim khoom siab, me me deformation ntawm vuam, thiab yooj yim automation.

1. Qhov sib txawv ntawm kev siv vuam tsis kam thiab kev tiv thaiv brazing rau Copper Cap thiab Fuse Riam

Resistance welding Copper Cap thiab Fuse End Tag yog ib txoj hauv kev siv lub zog los ntawm electrodes tom qab sib txuas cov khoom ua haujlwm tooj liab thiab Fuse Txuas Txuas, thiab siv cov hluav taws xob tam sim no los ntawm kev sib cuag ntawm qhov sib koom ua ke thiab cov cua sov ua haujlwm nyob rau hauv qhov chaw uas nyob ib sab mus rau vuam. Resistance welding Copper Cap thiab Fuse Terminal yog ib txoj hauv kev siv cov hluav taws xob tam sim no ntws los ntawm qhov chaw sib chwv thiab cov chaw nyob ib sab ntawm lub workpiece kom sov nws mus rau lub xeev molten los yog yas los tsim ib daim ntawv cog lus hlau. Muaj plaub txoj hauv kev tseem ceeb ntawm kev tiv thaiv vuam Copper Cap thiab Fuse Contact, uas yog qhov chaw vuam, seam vuam, projection vuam thiab pob tw vuam.

Brazing Copper Cap thiab Fuse Terminal Sib cuag yog siv cov khoom siv hlau uas muaj qhov qis qis dua li cov hlau hauv lub hauv paus raws li cov hlau solder, ua kom sov lub vuam thiab cov vuam mus rau qhov kub siab tshaj qhov melting point ntawm solder thiab qis dua lub melting kub. lub hauv paus hlau Copper End Caps Round thiab Fuse Txuas Kev Sib cuag, thiab siv cov kua nplaum los ntub cov hlau hauv paus los sau qhov sib koom ua ke thiab Ib txoj hauv kev sib txuas weldments los ntawm interdiffusion nrog lub hauv paus hlau. Lub brazing deformation yog me me, qhov sib koom ua ke yog du thiab zoo nkauj, thiab nws yog tsim rau precision vuam. Ua ntej brazing Outer Cap thiab Automotive Fuse Terminals, lub workpiece yuav tsum tau ua tib zoo ua tiav thiab nruj me ntsis ntxuav kom tshem tawm cov roj stains thiab tuab oxide zaj duab xis ntau dhau los xyuas kom meej qhov sib txuas sib txuas. Qhov sib txawv feem ntau yuav tsum nyob nruab nrab ntawm {{0}}.01 thiab 0.1 hli.

2. Yuav ua li cas tom qab vuam tu ntawm kev tiv thaiv brazing Copper Cap thiab Fuse End Blade Femules?

Feem ntau ntawm cov flux residues muaj cov nyhuv corrosive ntawm cov pob qij txha brazed, thiab tseem cuam tshuam rau kev tshuaj xyuas ntawm cov pob qij txha tooj liab hlau kawg Cap thiab Fuse Txuas Sib cuag, thiab feem ntau yuav tsum tau ntxuav. Cov residue ntawm cov dej ntws uas muaj rosin tuaj yeem raug tshem tawm nrog cov kuab tshuaj organic xws li isopropanol, cawv thiab trichloroethylene. Fluxes uas muaj cov organic acids thiab ntsev feem ntau yog soluble hauv dej thiab tuaj yeem ntxuav nrog dej kub. Mos fluxes muaj li ntawm inorganic acids yog soluble nyob rau hauv dej thiab yog li ntawd yuav tsum tau ntxuav nrog dej kub. Fluxes uas muaj alkali hlau thiab alkaline ntiaj teb hlau chlorides (xws li zinc chloride) tuaj yeem ntxuav nrog 2% hydrochloric acid tov. Cov borax thiab boric acid flux residues siv rau brazing Copper End Cap thiab Fuse Terminal Sib cuag yog qhov yooj yim insoluble hauv dej thiab nyuaj rau tshem tawm. Feem ntau, sandblasting yog siv los tshem tawm lawv. Ib txoj hauv kev zoo dua yog muab lub pob zeb ua haujlwm tooj liab kawg Caps thiab Fuse Sib cuag hauv dej hauv lub xeev kub, kom cov dej ntws tawm tau tawg thiab yooj yim tshem tawm. Cov residue ntawm brazing Copper Cap thiab L-Type Termial fluxes uas muaj cov poov tshuaj fluoroborate lossis potassium fluoride (xws li tus neeg sawv cev 102) tuaj yeem raug tshem tawm los ntawm boiling los yog hauv 10% citric acid dej kub.

Vuam kev ua tau zoo ntawm tooj liab stamping qhov chaw Fuse End Cap thiab Tiv tauj

1. Muaj zog thermal conductivity, Fuse Copper Contact Riam Cap muaj cov thermal conductivity siab, thiab yuav tsum muaj lub zog hluav taws xob siab; preheating lub weldment yuav siv tau rau vuam End Cap thiab Tiv tauj.

2. Lub fluidity yog loj, thiab molten tooj liab kua muaj fluidity zoo, thiab tsuas yog welded nyob rau hauv lub tiaj vuam txoj hauj lwm. Yog hais tias ib sab pob tw vuam yuav tsum tau ua nyob rau hauv ib tug spatial txoj hauj lwm, ib tug thaub qab phaj yuav tsum tau ntxiv los xyuas kom meej nkag mus thiab tau txais kev zoo.

3. Lub thermal expansion thiab txias contraction yog loj, thiab cov coefficient ntawm linear expansion ntawm Copper End Cap thiab Contact Vuam Cheebtsam yog loj, thiab qhov tshwm sim ntawm thermal expansion thiab txias contraction thaum lub sij hawm vuam txheej txheem yog tshwj xeeb tshaj yog pom tseeb, yog li lub deformation tom qab vuam. yog loj.

4. Oxidation, tooj liab ntawm Design Welded Joints yog yooj yim oxidized nyob rau hauv cov kua hauv lub xeev los ua cuprous oxide, uas yog yaj nyob rau hauv tooj liab kua. Thaum lub sij hawm crystallization, ib tug eutectic nrog ib tug qis melting point yog tsim, uas muaj nyob rau ntawm lub grain ciam teb ntawm tooj liab End Cap thiab Terminal, uas txo cov plasticity thiab yooj yim ua rau tawg.

5. Stomata, solubility ntawm hydrogen hauv kua tooj liab yog loj heev; Tom qab solidification, lub solubility txo qis dua. Thaum lub sij hawm vuam Outer Cap thiab kev sib cuag, cov vuam seam txias sai heev, thiab cov hydrogen ntau dhau tsis muaj sij hawm khiav tawm, yog li hydrogen qhov tsim. Tsis tas li ntawd, lub khob oxide ntawm qhov kub siab reacts nrog hydrogen thiab carbon monoxide los tsim cov dej vapor thiab carbon dioxide. Yog tias lawv tsis tuaj yeem khiav tawm tag nrho ua ntej solidification, pores kuj yuav tsim.
