Ua kom tiav cov tshuaj kom pom cov txheej txheem welding

01.Spot Vuam txheej txheem

Chaw vuam, raws li lub npe qhia, yog txheej txheem ntawm cov cua kub hauv zos thiab tom qab no ua tiav qhov chaw sib txuas, qhov ua tiav qhov chaw sib txuas ntawm cov hlau hlau. Hauv kev lag luam ntau lawm, chaw welding yog siv rau splicing, txhawb nqa, thiab txuas cov ntawv hlau.

Chaw welding yog feem ntau thov nyob rau hauv cov chaw hauv qab no:

1. Cov khoom lag luam Automotive: tuaj yeem siv rau vuam lub cev sib xyaw, chassis, tshuab lub tshuab lub qhov rooj, thiab cov qauv ncej. Tshwj xeeb tshaj yog nyob rau hauv cov kev sib tshooj thiab kho ntawm lub cev hlau stamping, chaw welding tshuab siv lub luag haujlwm tseem ceeb

2. Lithium roj teeb tsim: siv rau vuam qhov zoo thiab tsis zoo electrodes ntawm roj teeb kom ntseeg tau tias lawv txoj kev nyab xeeb thiab kev pabcuam lub neej.

3. AERPARACE: Siv dav rau Welding tseem ceeb xws li aircraft fuselage, tis, Xyaw, thiab lwm yam.

4. Khoom siv hauv tsev: feem ntau yog siv rau vuam thiab kho cov qauv nyias phaj. Cov khoom lag luam xws li cov tshuab cua txias, tub yees, ntxhua khaub ncaws, thiab lwm yam

5. Electronic thiab hluav taws xob Cheebtsam kev lag luam: Chaw Welding Technology yog siv nyob rau hauv vuam ntawm cov nyiaj sib cuag ntawm ntau yam khawm thiab hluav taws xob.

6. Lwm cov chaw tsim khoom lag luam: Ntxiv rau cov xim sib txawv, cov chaw welding nyob rau hauv cov hlau, kev tsim kho, cov nkoj, cov nqaj hlau, thiab petrochemicals.

02.Cracteristic

Thaum lub sij hawm chaw chaw vuam, welded ib qho kev ua ke ncej puab thiab yog compressed ntawm ob electrodes. Nws cov yam ntxwv tseem ceeb muaj raws li hauv qab no:

1. Kev siv hluav taws xob nrawm nrawm: vim qhov tseeb uas chaw vuam tsuas yog ua kom lub zog luv luv ntawm thaj chaw sib txuas hauv zos thiab muaj lub tshuab hluav taws xob luv luv thiab cov khoom siv nrawm nrawm yog qhov siab.

2. Ruaj khov thiab txhim khu kev qha vuam, lub caij sov rau kev sib txuas yog qhov chaw sov heev, thiab nws tsis yooj yim rau tawg. Meanwhile, vim yog qhov tseeb uas chaw vuam tsuas yog siv hluav taws xob siv hluav taws xob thiab tsis tas yuav ntim cov khoom siv, flux, roj av, thiab lwm yam.

3. Qib siab ntawm kev siv tshuab thiab automation: qhov chaw welding tshuab tau txais ib qho kev tswj hwm lub cev, uas tuaj yeem ua tiav kev ua haujlwm txuas ntxiv thiab txhim kho ntau lawm. Nyob rau tib lub sijhawm, chaw welding tshuab Siv elecural siab rau vuam, uas tuaj yeem zam kev ua yuam kev los ntawm kev ua haujlwm los ntawm kev coj ua kev sib tw los ntawm kev ua haujlwm ntawm kev ua yeeb yam.

4. Tsawg txoj hauj lwm siv zog: chaw welding tshuab yog yooj yim rau kev ua haujlwm thiab muaj qib siab ntawm kev siv tshuab thiab kev siv tsheb, ua rau muaj kev ua haujlwm qis dua rau cov neeg ua haujlwm.

5. High equipment cost: Due to the high current and pressure required for welding with spot welding machines, the power of the equipment is relatively high and the cost is high. Lub caij no, vim kev siv hluav taws xob rau vuam nyob rau hauv cov chaw welding tshuab, tus nqi ntawm cov khoom siv rau cov electrodes kuj tseem muaj siab.

6. Nws yog qhov nyuaj rau kev sim ua tsis zoo ntawm vuam cov ntsiab lus: vim kev kuaj cua sov luv luv thiab kev ua kom nrawm nrawm ntawm vuam cov ntsiab lus yog qhov nyuaj.

03. Cov Txheej Txheem Txheej Txheem

Ua ntej vuam, saum npoo ntawm workpiece yuav tsum tau huv si. Qhov feem ntau siv tu tu cov txheej txheem yog kua tshuaj ntxuav, uas cuam tshuam nrog thawj cov pickling hauv rhuab roj acid nrog lub tswv yim ntawm 10%, thiab tom qab ntawd yaug hauv dej kub. Cov txheej txheem vuam yog raws li hauv qab no:

(1) Ntxig cov workpiece sib koom tes nruab nrab ntawm sab saud thiab qis electrodes ntawm cov chaw welding tshuab thiab clamp nws nruj nreem;

(2) hluav taws xob tau thov kom ua kom sov rau ntawm ob lub workpieces, ua rau cov neeg ua haujlwm hauv nroog, ua rau MancesT Code;

(3) tswj lub siab tom qab fais fab, cia cov tub ntxhais kawm molten kom txias thiab ua rau cov pob qij txha hauv cov pob qij txha;

(4) Tshem lub siab thiab tawm mus ua haujlwm.

04.Influence Factor

Lub ntsiab tseem ceeb ntawm vuam zoo xws li vuam tam sim no thiab lub sij hawm energization, electrode siab, thiab kev ua si hluav taws xob, thiab kev ua si hluav taws xob, thiab kev hloov pauv tshiab.

1. Vuam tam sim no thiab lub sijhawm lom zem

Cov chaw welding tuaj yeem faib ua ob hom: siv cov lus qhia nyuaj thiab cov khoom siv muag muag, raws li qhov ntau ntawm vuam tam sim no thiab ntev ntawm hluav taws xob lub sijhawm. Qhov tshwj xeeb ntawm kev hla siab tam sim no hauv lub sijhawm luv luv yog hu ua qhov zoo ntawm welded, thiab yog haum rau vuam cov hlau nrog cov thermal conductivity. Ib qho kev qhia tshwj xeeb uas siv me me tam sim no rau lub sijhawm ntev dua yog hu ua kev tsim khoom muag, uas muaj cov khoom lag luam muag khoom ntxiv nrog cov hlau sib tw nrog cov nyiam ntawm quenching thiab tawv.

2. Electrode siab siab

Thaum cov chaw vuam, lub siab thov rau lub workpiece los ntawm electrode yog hu ua electrode siab. Cov khoom tsim nyog rau pob hluav taws xob tsim nyog tuaj yeem ua tib zoo sib tiv toj ntawm cov hlau hauv lub chaw vuam, txhawb kev hloov pauv thaum tshav kub. Thaum lub siab yog siab, nws tuaj yeem tshem tawm cov shrinkage thiab porosity uas yuav tshwm sim thaum lub solidification ntawm Weld Core. Txawm li cas los xij, qhov qis dua hauv kev tawm tsam thiab cov ntom ntom ntom nti thaum lub sij hawm weld tsis txaus, thiab txo qis hauv lub zog ntawm weld sib koom tes. Qhov ntau ntawm electrode siab tuaj yeem xaiv raws li cov hauv qab no:

(1) cov khoom siv ntawm welded tivthaiv. Qhov siab dua qhov siab-kub lub zog ntawm cov khoom, qhov ntau dua qhov yuav tsum tau muaj hluav taws xob siab. Yog li ntawd, thaum vuam stainless hlau thiab kub-resistant steel, muaj ntau dua electrode siab yuav tsum tau siv tshaj li thaum vuam Qhab hlau.

(2) Vuam qhov tsis sib tw. Qhov nyuaj rau cov vuam qhov kev paub sib tw, qhov ntau dua cov hluav taws xob siab.

3. Kev Ua Si

Thaum cov chaw vuam, ntws tawm tam sim no sab nraum lub ntsiab vuam yog hu ua shunt. Qhov kev sib txawv txo qhov kev ntws tam sim no los ntawm qhov chaw vuam, ua rau muaj cua sov tsis txaus thiab txo qis ntawm vuam muag, uas cuam tshuam rau cov vuam zoo. Qhov cuam tshuam uas cuam tshuam rau qib kev ua si tshwj xeeb tsuas yog suav nrog cov hauv qab no:

(1) vuam tuab thiab txuas ntawm vuam cov ntsiab lus. Raws li qhov kev ncua deb ntawm cov pob qij txha sib npaug Thaum siv cov ntsiab lus sib txuas ntawm 30-50mm, lub tso dag tam sim no rau 25% rau 40% ntawm tag nrho cov tam sim no, thiab qib ntawm kev txaj muag txo qis ntawm weldment txo qis.

(2) cov khoom sib txawv ntawm cov khoom siv welded. Thaum muaj cov oxides lossis av ntawm cov npoo ntawm welded, kev sib cuag ntawm ob welded qhov chaw txo qis, uas yog, qib kev sib tw nce. Lub workpiece tuaj yeem yog pickled, sandblasted lossis polished.

05.Safety Ceev Faj

(1) Tus taw hloov ntawm cov tshuab vuam yuav tsum muaj kev tiv thaiv kev tiv thaiv khov kho kom tiv thaiv kev ua haujlwm tsis zoo kom tsis txhob ua haujlwm.

(2) Cov haujlwm nqa los ua tom tsev yuav tsum tau nruab nrog ib qho kev sib tw tiv thaiv kev tiv thaiv ntawm kev sib txig.

(3) Welders yuav tsum hnav lub ntsej muag lub ntsej muag zais iav, hnab looj tes, khaub ncaws ua haujlwm, thiab lwm yam thaum vuam

(4) Qhov chaw uas cov vuam tshuab vuam yuav tsum tau khaws cia qhuav, thiab hauv av yuav tsum tau them nrog kev tiv thaiv npleem.

(5) Tom qab vuam ua haujlwm tiav, lub zog yuav tsum tau txiav, thiab cov dej txias txias yuav tsum tau txuas ntxiv rau 10 vib nas this ua ntej muab tua. Thaum qhov ntsuas kub tsawg, cov dej muaj roj nyob hauv cov dej yuav tsum tau nqus kom tiv thaiv kom khov.
