Mid-frequency spot welding yog cov txheej txheem siv dav hauv ntau yam kev lag luam, xws li tsheb thiab kev tsim khoom, rau kev koom nrog cov khoom siv hlau.Ua kom ntseeg tau qhov zoo ntawm cov pob qij txha no yog qhov tseem ceeb los tswj cov khoom lag luam thiab kev nyab xeeb.Kab lus no yuav delve rau hauv kev tshuaj xyuas ntawm cov teeb meem zoo sib xws nrog rau nruab nrab zaus qhov chaw vuam pob qij txha.
Qhov teeb meem zoo 1: Weld Porosity Weld porosity yog hais txog qhov muaj cov voids me me los yog kab noj hniav hauv qhov sib koom ua ke, uas tuaj yeem ua rau cov qauv tsis muaj zog thiab txo qhov kev ncaj ncees tag nrho ntawm cov vuam.Ntau yam tuaj yeem ua rau muaj qhov sib txawv ntawm qhov sib txawv, suav nrog cov roj tiv thaiv tsis zoo, cov khoom siv vuam tsis raug, lossis cov hlau tsis huv.Kev tswj xyuas zoo, xws li kev saib xyuas roj thiab kev saib xyuas cov khoom siv vuam tsis tu ncua, yog qhov tseem ceeb los daws qhov teeb meem no.
Qhov Teeb Meem Zoo 2: Weld Cracking Weld cracking, los yog tsim cov kab nrib pleb hauv qhov sib koom ua ke, yog lwm qhov kev txhawj xeeb zoo.Nws tuaj yeem tshwm sim vim qhov txias txias ntawm qhov vuam, tsis txaus preheating, los yog muaj kev ntxhov siab ntau.Kev tiv thaiv kev tiv thaiv zoo li kev tswj cov cua txias, siv cov txheej txheem preheating kom zoo, thiab siv cov ntaub ntawv muab tub lim tsim nyog tuaj yeem pab txo qis kev sib tsoo.
Qhov teeb meem zoo 3: Kev nkag mus tsis tiav Incomplete penetration tshwm sim thaum lub vuam tsis ncav cuag tag nrho cov tuab ntawm cov khoom siv hauv paus, ua rau muaj kev sib koom ua ke tsis muaj zog.Cov laj thawj uas ua rau qhov teeb meem no suav nrog qhov tsis raug welding tam sim no, qhov loj ntawm electrode tsis tsim nyog, lossis kev npaj tsis sib xws.Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia txaus thiab tsis tu ncua xyuas lawv cov khoom siv vuam kom ntseeg tau tias kev nkag mus tau zoo thiab sib koom ua ke zoo.
Qhov teeb meem zoo 4: Weld Spatter Weld spatter yog ejection ntawm molten hlau hais thaum lub vuam txheej txheem, uas tuaj yeem ua rau muaj kev nyab xeeb thiab txo qhov zoo nkauj.Kev hnav khaub ncaws zoo electrode, tswj xyuas qhov chaw ua haujlwm huv, thiab kho qhov vuam tsis tuaj yeem txo qhov tshwm sim ntawm qhov sib tsoo.
Qhov Teeb Meem Zoo 5: Electrode Hnav Cov xwm txheej ntawm vuam electrodes plays lub luag haujlwm tseem ceeb hauv kev ua tiav cov vuam zoo.Electrode hnav, tshwm sim los ntawm tej yam xws li ntau dhau tam sim no lossis tsis txaus cua txias, tuaj yeem ua rau kev sib koom ua ke tsis zoo thiab nce nqi kho.Ua raws li kev saib xyuas electrode thiab hloov lub sijhawm tuaj yeem pab daws qhov teeb meem no.
Xaus: Ua kom ntseeg tau qhov zoo ntawm qhov nruab nrab ntawm qhov chaw vuam pob qij txha yog qhov tseem ceeb rau kev tswj xyuas cov khoom ncaj ncees thiab kev nyab xeeb hauv ntau yam kev lag luam.Los ntawm kev daws cov teeb meem zoo xws li weld porosity, cracking, incomplete penetration, weld spatter, and electrode wear, manufacturers tuaj yeem txhim kho lawv cov txheej txheem vuam thiab tsim cov khoom siv vuam zoo, txhim khu kev qha zoo.Kev tswj xyuas kev ua tau zoo, kev cob qhia tus neeg ua haujlwm, thiab kev saib xyuas cov khoom siv tsis tu ncua yog qhov tseem ceeb hauv kev ua kom tau zoo ib yam, zoo welds.
