Pitfalls nyob rau hauv Teem Vuam Parameters: Struggling nrog Spot Welding? Tsis txhob ua yuam kev no

Novices tshiab rau qhov chaw vuam feem ntau ntsib teeb meem xws li tsis muaj zog welds (txias welds), hlawv-los ntawm, hnyav workpiece deformation, thiab electrode sticking. Kev hloov kho cov cuab yeej rov ua dua feem ntau tsis ua tiav cov txiaj ntsig tau txais txiaj ntsig, feem ntau vim tias tus neeg siv tau poob rau hauv qhov tsis txaus ntseeg txog kev teeb tsa parameter. Peb tau muab tso ua ke ib daim ntawv teev cov feem ntau yuam kev beginners ua thaum teeb tsa lub tshuab, piav qhia lawv qhov tshwm sim, thiab tau piav qhia txog cov kev hloov kho kom raug los pab koj kom zam dhau qhov yuam kev no.

Qhov muag tsis pom kev luam tawm yam tsis xav txog tej yam kev ua haujlwm

Ntau tus neeg pib tsuas yog siv cov kab kos duab pom hauv online lossis los ntawm lwm lub Hoobkas yam tsis xav txog qhov sib txawv ntawm cov khoom siv, tuab, lossis qhov chaw. Piv txwv li, siv cov kev txwv npaj rau 1 hli carbon steel ncaj qha mus rau 0.8mm stainless hlau workpiece tuaj yeem ua rau kub hnyiab tau yooj yim.

Txoj hauv kev kom raug yog thawj zaug txheeb xyuas cov khoom siv thiab qhov tseeb ntawm qhov workpiece. Tom qab ntawd, siv cov cuab yeej siv phau ntawv qhia cov lus pom zoo raws li qhov pib, maj mam kho peb qhov tseem ceeb - tam sim no, siab, thiab lub sijhawm - los ntawm qis dua mus rau qhov tseem ceeb dua. Ua qhov ntsuas welds ntawm cov khoom seem ua ntej kom ntseeg tau tias lub zog vuam thiab zoo li raws li cov qauv ua ntej yuav mus rau ntau lawm.

Kho tsuas yog vuam tam sim no thaum tsis quav ntsej electrode siab

Ntau tus pib xav tias qhov tsis muaj zog weld yog tshwm sim los ntawm qhov tsis txaus tam sim no thiab ua kom nws nce ntxiv yam tsis tau ua kom cov electrode siab zoo sib xws. Piv txwv li, thaum vuam tuab daim hlau, yog tias electrode siab tsis txaus, daim hlau yuav tsis haum nruj ua ke. Txawm tias muaj qhov siab tam sim no, tsis sib npaug ntawm cov cua sov tuaj yeem ua rau thaj chaw tsis muaj zog welds thiab nto pitting.

Qhov tseeb logic yog ua ntej sib tw lub electrode siab rau lub workpiece thickness kom paub tseeb tias cov phaj haum nruj nreem tsis muaj qhov khoob. Tom qab ntawd, kho qhov tam sim no kom tau raws li qhov yuav tsum tau ua kom sov. Tsuas yog los ntawm synchronizing siab thiab tam sim no koj tuaj yeem ua tau zoo, ruaj khov welds.

Teem lub sij hawm vuam heev - ntev dhau los lossis luv dhau

Cov pib tshiab feem ntau mus rau qhov kawg thaum teeb tsa lub tshuab: txawm tias teeb tsa lub sijhawm luv luv rau kev ntshai ntawm kev kub nyhiab-los ntawm qhov ua rau muaj cua sov tsis txaus, tsis ua rau lub vuam tsis muaj zog, thiab lub vuam tsis muaj zog-los yog teeb lub sij hawm ntev heev rau kev ntshai ntawm qhov tsis muaj zog weld-ua rau kub tsub zuj zuj, qhov loj ntawm tshav kub-tshem tawm tsam, thiab workpiece deformation. Thaum pom cov ntawv nyias nyias ntawm cov hlau tsis tshua muaj cov pa roj carbon monoxide, lub sij hawm vuam feem ntau yog tswj tsis pub dhau 0.1s-0.3s. Tus txheej txheem rau kev vam meej yog tsim kom tiav weld nugget yam tsis muaj qhov tseem ceeb nto overheating los yog discoloration; zam qhov kev txiav txim siab teem caij ntev uas dhau ntawm cov khoom lag luam cov lus pom zoo.

Kev tsis saib xyuas parameter them nyiaj rau electrode hnav

Tom qab siv sijhawm ntev, cov lus qhia vuam electrode hnav thiab nthuav dav, ua rau thaj chaw sib cuag. Qhov no txo ​​qhov ceev tam sim no ntawm ib cheeb tsam, ua rau 'txias welds' (tsis muaj zog bonds) yuav. Ntau tus novices tsis pom qhov kev hloov pauv no thiab txuas ntxiv siv cov kev txwv qub, ua rau lub zog tsis zoo-feem ntau yuam kev vim qhov teeb meem rau cov khoom siv tsis ua haujlwm.

Tsis tu ncua tshuaj xyuas cov lus qhia electrode thaum lub sijhawm ua haujlwm txhua hnub thiab hnav khaub ncaws (sib tsoo / flatten) kom sai li sai tau thaum hnav. Yog tias lub zog weld poob tom qab hnav khaub ncaws, me ntsis nce qhov vuam tam sim no los ntawm 5% -10% txhawm rau them nyiaj rau qhov poob ntawm qhov tam sim no ntom ntom los ntawm qhov chaw sib cuag.

Siv cov kev txwv rau ib qho khoom siv thaum vuam cov khoom sib txawv

Thaum qhov chaw vuam sib txawv ntawm cov hlau tsis sib xws - xws li carbon steel rau stainless hlau, lossis hlau rau cov ntawv galvanized - cov novices feem ntau siv cov chaw npaj rau ib qho ntawm cov ntaub ntawv. Vim hais tias thermal conductivity thiab melting cov ntsiab lus sib txawv ntawm ob, cov cua sov faib ua tsis sib xws; Qhov no feem ntau ua rau tsis txaus fusion ntawm ib sab lossis hlawv-los ntawm lwm qhov.

Thaum vuam cov hlau tsis sib xws, kho qhov tsis sib xws raws li cov khoom siv nrog cov thermal conductivity qis dua thiab cov ntsiab lus melting ntau dua. Tsis tas li ntawd, kho cov khoom siv hluav taws xob thiab lub taub taub kom sib npaug ntawm cov khoom siv hluav taws xob, kom ntseeg tau tias cov ntaub ntawv weld nugget tsim nyog hauv ob qho tib si.

PDKJ yog cov chaw tsim khoom ntawm cov khoom siv vuam tshuab. Peb cov cuab yeej los nrog lub tsev qiv ntawv built-in siv ntawm cov kev txwv rau ntau yam ntaub ntawv thiab thicknesses, tso cai rau cov novices sai sai tswv lub tshuab teeb. Peb kuj muab cov kev taw qhia kev ua haujlwm pub dawb thiab kev sim-vuam cov kev pabcuam los pab koj kom tsis txhob muaj kev cuam tshuam hauv kev teeb tsa parameter thiab xyuas kom muaj qhov zoo sib xws. Xav tias dawb hu rau peb rau kev sab laj.
