Spot welding yog ib hom kev siv tshuab vuam uas muaj keeb kwm ntev, uas yog tsim los ntawm vuam qhov chaw sib sau ua ke rau hauv ib lub puab tsaig thiab nias ntawm ob lub electrodes, thiab siv cov hluav taws kub kub los yaj lub hauv paus hlau los ua ib qho chaw vuam.
Cov khoom siv vuam yog txuas nrog lub me me molten core, uas yuav tsum sib npaug thiab sib npaug ntawm qhov sib txuas ntawm ob lub welds, thiab muaj cov yam ntxwv ntawm vuam nyob rau hauv siab tam sim no, lub sij hawm luv luv thiab siab.
Spot welding yog ib qho hluav taws xob-mechanical (force) sib koom ua haujlwm ntawm cov txheej txheem vuam, raws li daim ntawv ntawm cov khoom siv hluav taws xob tuaj yeem muab faib ua ib sab vuam thiab ob sab vuam, tuaj yeem welded nyob rau hauv ib lub sij hawm luv luv, yog li ua haujlwm siab. Thaum tshav kub kub yog concentrated nyob rau hauv ib feem, cov khoom welded tsis tshua muaj tshwm sim thermal deformation, thiab vuam zoo yog zoo. Vim tias nws yog vuam tsis siv neeg, leej twg tuaj yeem vuam, thiab tsis tas yuav tsum muaj kev ua haujlwm.
Lub rationality ntawm vuam chaw npaj ntawmnruab nrab zaus qhov chaw vuam tshuab: Spot welding qauv feem ntau yog ua los ntawm ntau yam kev sib txuas, nws txoj kev npaj yog feem ntau ib kab, qee zaum kuj tuaj yeem ua ntau kab, nyob rau hauv ib kab ib leeg qhov chaw vuam sib koom ua ke ntxiv rau cov kev nyuab siab shear, tab sis kuj dais tensile kev nyuaj siab los ntawm eccentric quab yuam. , nyob rau hauv ib tug ntau-kab qhov chaw welding ob leeg, tensile kev nyuaj siab yog me me, kev tshawb fawb qhia tau hais tias tus naj npawb ntawm solder pob qij txha ntau tshaj 3 yog tsis tsim nyog, vim hais tias ntau tshaj 3 kab tsis tuaj yeem ua rau cov kabmob muaj peev xwm.
Nyob rau tib lub sijhawm, nws yuav tsum tau muab sau tseg tias ib kab ntawm qhov chaw welded pob qij txha yog tsis yooj yim sua kom ua tiav lub zog ntawm kev sib koom ua ke thiab lub hauv paus hlau, tsuas yog siv ntau kab (3 kab) txheej txheem cov pob qij txha, tuaj yeem txhim kho qhov cuam tshuam. ntawm ib feem ntawm lub zog hluav taws xob, txo qhov kev ntxhov siab coefficient, yog tias siv txoj kev staggered kab, qhov xwm txheej yuav zoo dua, hauv kev xav, koj tuaj yeem tau txais ib qho chaw welded sib koom nrog lub zog ntawm lub hauv paus hlau.
Peb yuav ntsib qhov tshwm sim ntawm kev txaws thaum ua haujlwm ntawm qhov nruab nrab zaus qhov chaw vuam tshuab, uas tuaj yeem ua rau yooj yim khawb ntawm cov hlau hauv paus, kis kab mob ntawm cov kaus mom hlau tiv thaiv lub kaus mom, thiab cov iav frosted ntawm lub lim thiab lub koob yees duab. Yog li koj yuav tiv thaiv qhov no li cas?
Nyob rau hauv tus txheej txheem ntawm kev khiav hauj lwm, lub interface ntawm vuam sai sai melts nyob rau hauv ib tug luv luv lub sij hawm, lub tshav kub ntawm cov hlau nce instantaneously, lub melted kua yog lig dhau lawm txias, thiab cov kua yog sprayed tawm ntawm lub molten core nyob rau hauv qhov kev txiav txim ntawm lub siab. , ua rau muaj txaws.
Muaj kev tshaj tawm cua sov Q = I²RT, uas qhia tau hais tias spatter yog ib qho yooj yim tshwm sim thaum tshav kub kub heev, yog li spatter yuav tswj tau los ntawm lub kaum sab xis ntawm tam sim no thiab kuj; Tam sim no ceev: muaj av nyob rau saum npoo ntawm lub workpiece los yog muaj qhov sib txawv ntawm lub workpiece. Electrode: Electrode cap asymmetry los yog hnav tam sim no ceev nce spatter nce.
Thaum ntxov splash:
Weld tu tsis tsim nyog, lub siab faib rau ntawm qhov chaw sib chwv yog qhov tsis sib xws, uas ua rau thaum ntxov melting tshwm sim los ntawm lub zos tam sim no ceev ceev, nyob rau lub sij hawm no vim tsis muaj cov yas tiv thaiv yuav inevitably tshwm sim splashing tshwm sim.
Late splash:
Lub melting core loj hlob thiab kev hloov pauv, dhau ntawm qhov ua tau zoo ntawm electrode siab, thiaj li ua txhaum ntawm lub nplhaib yas nyob rau hauv radial ua rau sab hauv splashing, ua rau sab nraud splashing ntawm lub axial so nto, qhov teeb meem no feem ntau ua nyob rau hauv lub tam sim no loj. , lub sijhawm hluav taws xob ntev dhau lawm, tuaj yeem txo lub sijhawm fais fab thiab txo cov qauv tam sim no los tiv thaiv.
