01.Kev piav qhia luv luv
Spot welding yog ib txoj kev siv vuam tsis kam uas vuam qhov chaw tau sib sau ua ke rau hauv cov pob qij txha thiab nias ntawm ob lub electrodes, siv cov cua sov ua kom yaj lub hauv paus hlau los ua cov pob qij txha.
Spot welding feem ntau yog siv hauv cov hauv qab no:
1. Kev sib tshooj ntawm nyias phaj stamping qhov chaw, xws li tsheb cab, cov khoom ntim, cov khoom siv ntses ntses nplai, thiab lwm yam.
2. Nyias phaj thiab zoo li tus steel qauv thiab cov qauv ntawm daim tawv nqaij, xws li carriage sab phab ntsa thiab qab nthab, trailer carriage panels, ua ke harvester funnels, thiab lwm yam.
3. Cov ntxaij vab tshaus, qhov chaw thav duab thiab ntoo khaub lig steel tuav, thiab lwm yam.
02. Nta
Thaum lub sij hawm welding, lub weldment tsim ib qho sib tshooj sib tshooj thiab nias ntawm ob lub electrodes. Nws lub ntsiab nta yog raws li nram no:
1. Thaum lub sij hawm qhov chaw vuam, lub sij hawm cua sov ntawm qhov chaw sib txuas yog luv heev thiab vuam ceev yog ceev.
2. Spot welding tsuas yog siv lub zog hluav taws xob thiab tsis xav tau cov ntaub ntawv sau, flux, roj, thiab lwm yam.
3. Qhov zoo ntawm qhov chaw vuam yog tsuas yog lav los ntawm qhov chaw vuam tshuab. Nws muaj kev ua haujlwm yooj yim, qib siab ntawm kev siv tshuab thiab automation, thiab cov khoom lag luam siab.
4. Kev siv zog tsawg thiab kev ua haujlwm zoo.
5. Txij li thaum vuam ua tiav nyob rau hauv ib lub sij hawm luv luv thiab yuav tsum tau loj tam sim no thiab siab, qhov kev pab cuam tswj cov txheej txheem yog ntau nyuaj, lub vuam tshuab muaj ib tug loj hluav taws xob muaj peev xwm, thiab tus nqi ntawm cov cuab yeej yog kuj siab.
6. Nws yog ib qho nyuaj rau kev sim tsis muaj kev puas tsuaj ntawm cov pob qij txha.
Xinfa vuam cov cuab yeej muaj cov yam ntxwv zoo thiab tus nqi qis. Yog xav paub ntxiv, thov mus saib:Vuam & txiav Manufacturers - Tuam Tshoj Vuam & Txiav Hoobkas & lwm tus neeg (xinfatools.com)
03. Cov txheej txheem ua haujlwm
Ua ntej vuam, qhov saum npoo ntawm lub workpiece yuav tsum tau ntxuav. Kev siv tshuaj ntxuav tu feem ntau yog pickling, uas yog, nws yog thawj zaug pickled nyob rau hauv rhuab sulfuric acid nrog ib tug concentration ntawm 10%, thiab ces ntxuav nyob rau hauv dej kub. Cov txheej txheem vuam tshwj xeeb yog raws li hauv qab no:
(1) Pub cov khoom sib koom ua ke ntawm cov khoom siv hluav taws xob sab saud thiab qis ntawm qhov chaw vuam tshuab thiab clamp nws;
(2) Thaum siv hluav taws xob, qhov chaw sib cuag ntawm ob lub workpieces yog rhuab, ib nrab melted, thiab ib tug nugget yog tsim;
(3) Khaws lub siab tom qab lub hwj chim tawm, kom lub molten nugget txias thiab solidifies nyob rau hauv lub siab los ua solder pob qij txha;
(4) Tshem tawm lub siab thiab tshem tawm lub workpiece.
04.Influencing yam
Lub ntsiab cuam tshuam ntawm vuam zoo xws li vuam tam sim no thiab lub zog lub sij hawm, electrode siab thiab shunt, thiab lwm yam.
1. Vuam tam sim no thiab lub zog ntawm lub sijhawm
Raws li qhov loj ntawm qhov vuam tam sim no thiab qhov ntev ntawm lub zog ntawm lub sij hawm, qhov chaw vuam tuaj yeem muab faib ua ob hom: tawv gauge thiab mos ntsuas. Cov kev qhia tshwj xeeb uas dhau qhov tam sim no loj hauv lub sijhawm luv luv yog hu ua qhov tshwj xeeb nyuaj. Nws muaj qhov zoo ntawm kev tsim khoom siab, lub neej ntev electrode, thiab me me deformation ntawm vuam, thiab yog tsim rau vuam hlau nrog zoo thermal conductivity. Lub ntsuas hluav taws xob uas dhau los ntawm qhov tam sim no me dua nyob rau lub sijhawm ntev yog hu ua lub ntsuas hluav taws xob, uas muaj cov khoom lag luam qis dua thiab tsim nyog rau cov vuam hlau uas zoo li tawv.
2. Electrode siab
Thaum lub sij hawm qhov chaw vuam, lub siab exerted ntawm lub vuam los ntawm electrode yog hu ua electrode siab. Lub electrode siab yuav tsum raug xaiv kom tsim nyog. Thaum lub siab yog siab, lub shrinkage thiab shrinkage kab noj hniav uas yuav tshwm sim thaum lub nugget solidifies yuav raug tshem tawm. Txawm li cas los xij, qhov tsis kam thiab qhov ceev tam sim no ntawm cov electrode raug txo, uas ua rau cov cua sov tsis txaus ntawm cov vuam thiab txo qis hauv txoj kab uas hla ntawm cov nugget. Lub zog ntawm qhov sib koom ua ke txo qis. Qhov loj ntawm electrode siab tuaj yeem xaiv raws li cov hauv qab no:
(1) Cov khoom siv vuam. Qhov siab dua qhov kub siab zog ntawm cov khoom siv. Qhov siab dua electrode xav tau. Yog li ntawd, thaum welding stainless hlau thiab tshav kub-resistant steel, yuav tsum tau siv ib tug siab electrode siab tshaj thaum vuam uas tsis muaj carbon steel.
(2) Welding parameters. Qhov nyuaj ntawm vuam specification, qhov siab dua electrode.
3. Kev hloov pauv
Thaum lub sij hawm qhov chaw vuam, qhov tam sim no ntws tawm sab nraud lub ntsiab vuam Circuit Court yog hu ua shunt. Lub shunt txo qhov tam sim no ntws los ntawm qhov chaw vuam, ua rau cov cua sov tsis txaus, ua rau muaj qhov txo qis hauv lub zog ntawm cov vuam sib txuas thiab cuam tshuam rau vuam zoo. Cov yam ntxwv uas cuam tshuam rau qib kev hloov pauv feem ntau suav nrog cov hauv qab no:
(1) Weldment thickness thiab vuam taw tes sib nrug. Raws li qhov kev ncua deb ntawm cov pob qij txha nce, lub shunt kuj nce thiab qib ntawm shunting txo. Thaum siv cov ntsiab lus sib txawv ntawm 30 mus rau 50 hli, lub shunt tam sim no tso nyiaj rau 25% mus rau 40% ntawm tag nrho cov tam sim no, thiab raws li cov thickness ntawm cov weldment txo, cov degree ntawm shunting kuj txo.
(2) Deg mob ntawm vuam. Thaum muaj oxides los yog av nyob rau saum npoo ntawm lub welding, qhov kev sib cuag ntawm ob weldments nce, thiab tam sim no dhau los ntawm qhov vuam cheeb tsam txo, uas yog, qhov degree ntawm shunting nce. Lub workpiece tuaj yeem raug xaiv, sandblasted lossis polished.
05.Kev ceev faj txog kev nyab xeeb
(1) Lub ko taw hloov ntawm lub tshuab vuam yuav tsum muaj lub ntsej muag tiv thaiv kom tsis txhob muaj kev sib tsoo.
(2) Lub taw tes ua haujlwm yuav tsum tau nruab nrog baffles los tiv thaiv kev ua haujlwm ntawm kev ya.
(3) Welders yuav tsum hnav looj tsom iav thaum vuam.
(4) Qhov chaw uas lub tshuab vuam tau muab tso rau yuav tsum tau muab cia kom qhuav, thiab hauv pem teb yuav tsum tau pav nrog daim hlau tiv thaiv.
(5) Tom qab kev ua haujlwm vuam tiav lawm, cov khoom siv hluav taws xob yuav tsum raug txiav tawm, thiab qhov hloov dej txias yuav tsum tau txuas ntxiv rau 10 vib nas this ua ntej kaw. Thaum qhov kub thiab txias tsis tshua muaj, cov dej ntim hauv cov dej yuav tsum tau muab tshem tawm kom tsis txhob khov.
