01. Cov lus piav qhia luv luv
Spot welding yog ib txoj hauv kev ua haujlwm vuam uas cov vuam vuam tau sib sau ua ke rau hauv lub puab tsaig thiab nias ntawm ob lub electrodes, thiab lub hauv paus hlau yog yaj los ntawm cov cua sov los ntawm kev sib koom ua ke.
Spot welding feem ntau yog siv hauv cov hauv qab no:
1. Lap sib koom ua ke ntawm daim ntawv stamping qhov chaw, xws li tsheb cab, tsheb thauj neeg, ntses nplai npo ntawm cov qoob loo, thiab lwm yam.
2. Nyias phaj thiab seem steel qauv thiab daim tawv nqaij qauv, xws li sab phab ntsa thiab qab nthab ntawm carriages, trailer carriage panels, combines harvester funnels, thiab lwm yam.
3. Cov ntxaij vab tshaus, qhov chaw thav duab thiab ntoo khaub lig tuav, thiab lwm yam.
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
Qhov saum npoo ntawm lub workpiece yuav tsum tau ntxuav ua ntej vuam. Txoj kev tu siv feem ntau yog kev ntxuav tu, uas yog, pickling hauv rhuab sulfuric acid nrog ib tug concentration ntawm 10%, thiab ces ntxuav hauv dej kub. Cov txheej txheem vuam tshwj xeeb yog raws li hauv qab no:
(1) Xa 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) electrification, kom qhov chaw sib cuag ntawm ob lub workpieces yog rhuab thiab ib nrab melted los ua ib tug nugget;
(3) Khaws lub siab tom qab lub hwj chim txiav tawm, kom lub nugget txias thiab solidified nyob rau hauv lub siab los tsim ib tug solder sib koom;
(4) Tshem tawm lub siab thiab tshem tawm lub workpiece.
04. Muaj feem cuam tshuam
Lub ntsiab tseem ceeb cuam tshuam rau vuam zoo yog vuam tam sim no thiab lub zog lub sij hawm, electrode siab thiab shunt, thiab lwm yam.
1. Lub sijhawm vuam tam sim no thiab lub zog siv zog
Raws li qhov loj ntawm qhov vuam tam sim no thiab qhov ntev ntawm lub zog lub sij hawm, qhov chaw vuam tuaj yeem muab faib ua ob hom: tawv specification thiab mos specification. 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 cov khoom tsim tau zoo, lub neej ntev electrode, thiab me me deformation ntawm vuam. Nws yog tsim rau vuam hlau nrog zoo thermal conductivity. Ib qho kev qhia tshwj xeeb uas dhau qhov tam sim no me me rau lub sijhawm ntev yog hu ua cov lus qhia muag muag, uas muaj cov khoom lag luam qis dua thiab tsim nyog rau cov vuam hlau uas zoo li hardened.
2. Electrode siab
Thaum lub sij hawm qhov chaw vuam, lub siab exerted los ntawm electrode ntawm lub vuam yog hu ua electrode siab. Lub electrode siab yuav tsum tau xaiv kom raug. Thaum lub siab yog siab, nws tuaj yeem tshem tawm qhov shrinkage thiab shrinkage kab noj hniav uas yuav tshwm sim thaum lub nugget solidifies, tab sis qhov kev sib txuas kuj thiab tam sim no ceev txo, ua rau tsis txaus cua sov ntawm lub weldment thiab ib tug txo nyob rau hauv lub cheeb ntawm lub nugget. Lub zog ntawm qhov sib koom ua ke yog txo. Qhov loj ntawm electrode siab tuaj yeem xaiv raws li cov hauv qab no:
(1) Cov khoom siv welding. 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, lub electrode siab yuav tsum siab tshaj cov uas tsis muaj carbon steel.
(2) Welding parameters. Qhov nyuaj ntawm weld specification, qhov siab dua electrode.
3. xuuj
Thaum lub sij hawm qhov chaw vuam, qhov tam sim no ntws los ntawm sab nraud lub vuam lub ntsiab 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) Lub thickness ntawm vuam thiab qhov sib nrug ntawm cov pob qij txha. Raws li qhov kev ncua deb ntawm cov pob qij txha nce, lub shunt kuj nce thiab qib ntawm shunt txo. Thaum cov pa dot pitch ntawm 30-50mm yog saws, lub shunt tam sim no suav rau 25% -40% ntawm tag nrho cov tam sim no, thiab raws li lub thickness ntawm weldment txo, lub degree ntawm shunt kuj txo.
(2) Qhov saum npoo ntawm qhov vuam. Thaum muaj oxides los yog av nyob rau saum npoo ntawm lub vuam, qhov kev sib cuag ntawm ob lub weldment nce, thiab tam sim no los ntawm qhov vuam cheeb tsam txo, uas yog, qhov degree ntawm shunt nce. Lub workpiece tuaj yeem raug xaiv, sandblasted lossis polished.
05. Ceev faj txog kev nyab xeeb
(1) Lub ko taw hloov ntawm lub tshuab vuam yuav tsum muaj lub hau npog tiv thaiv kom tsis txhob muaj kev sib tsoo.
(2) Lub chaw ua haujlwm yuav tsum tau nruab nrog lub baffle los tiv thaiv kev tawg ntawm kev ua haujlwm.
(3) Welders yuav tsum hnav looj tsom iav thaum vuam.
(4) Qhov chaw uas lub tshuab vuam yog muab tso rau hauv qhov chaw yuav tsum tau qhuav, thiab hauv av yuav tsum tau npog nrog cov ntaub thaiv npog.
(5) Tom qab ua haujlwm vuam, lub zog hluav taws xob yuav tsum raug txiav tawm, thiab qhov hloov dej txias yuav tsum 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.
