Intermediate zauschaw vuam tshuabxav tau electrodes kom tiav cov txheej txheem vuam. Qhov zoo ntawm cov electrodes ncaj qha cuam tshuam qhov zoo ntawm cov welds. Electrodes feem ntau yog siv los xa cov tam sim no thiab siab rau lub workpiece. Txawm li cas los xij, kev siv cov khoom siv hluav taws xob tsis zoo tuaj yeem ua kom hnav thaum siv, ua rau muaj kev sib tsoo ntau dua thiab siv cov khoom siv raw. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv electrodes raws li cov ntaub ntawv raug welded.
Electrodes yuav tsum muaj ib theem ntawm high-temperature hardness, tshwj xeeb tshaj yog kom tswj tau qhov hardness ntawm kub ntawm 5000-6000 ° C. Kev kub siab kub hardness tiv thaiv electrode stacking thaum lub vuam txheej txheem. Feem ntau, qhov kub ntawm qhov chaw sib chwv ntawm lub workpiece thiab electrode thaum vuam yog li ntawm ib nrab ntawm lub melting point ntawm cov hlau welded. Yog hais tias cov khoom siv electrode muaj hardness siab ntawm qhov kub thiab txias tab sis tsis tshua muaj hardness thaum vuam, stacking tseem tuaj yeem tshwm sim.
Qhov kawg ua hauj lwm ntawm lub electrode tuaj nyob rau hauv peb daim duab: cylindrical, conical, thiab kheej kheej. Conical thiab spherical duab yog siv ntau dua vim lawv txhim khu kev txias thiab txo qhov kub ntawm electrode. Txawm hais tias spherical electrodes muaj lub neej ntev dua, kev ua kom sov sai dua, thiab zoo dua weld tsos, kev tsim khoom thiab tshwj xeeb tshaj yog kho lawv tuaj yeem nyuaj. Yog li ntawd, conical electrodes feem ntau nyiam.
Kev xaiv ntawm qhov chaw ua haujlwm yog nyob ntawm qhov siab thov. Ib qhov chaw ua haujlwm loj dua yog xav tau thaum lub siab siab los tiv thaiv kev puas tsuaj rau qhov kawg ntawm electrode. Yog li ntawd, raws li lub thickness ntawm lub phaj nce, txoj kab uas hla ntawm qhov chaw ua hauj lwm yuav tsum tau nce. Qhov chaw ua haujlwm maj mam hnav thiab nce thaum lub sijhawm ua haujlwm. Yog li ntawd, kev kho raws sij hawm yog tsim nyog thaum lub sij hawm vuam ntau lawm los tiv thaiv kom tsis txhob muaj qhov ntom ntom tam sim no ua rau txo qis fusion nkag los yog txawm tias tsis muaj fusion nucleus. Kev txais yuav ib txoj hauv kev uas tam sim no cia li nce nrog qhov nce ntawm cov welds tuaj yeem ncua lub sijhawm ntawm ob qho kev kho.
Yuav daws teeb meem me me li cas hauv Intermediate Frequency Spot Welding Machine?
Cov khoom siv tsis muaj hwj chim rau: qhov txawv txav ntawm lub tshuab thyristor, kev ua txhaum ntawm lub thawv tswj P board.
Cov khoom siv tsis ua haujlwm tom qab khiav: tsis txaus roj siab, tsis muaj cua compressed, txawv txav solenoid valve, kev ua haujlwm txawv txav, lossis tus maub los tsis siv, kev ua haujlwm ntawm qhov kub thiab txias.
Cov kab nrib pleb tshwm nyob rau hauv welds: ntau oxidation txheej ntawm lub workpiece nto, siab vuam tam sim no, tsis tshua muaj electrode siab, tsis xws luag nyob rau hauv lub welded hlau, misalignment ntawm lub qis electrode, tsis raug cov cuab yeej kho.
Tsis txaus lub zog ntawm cov ntsiab lus weld: tsis txaus electrode siab, seb tus pas nrig electrode yog nruj nreem.
Kev sib tsoo ntau dhau thaum vuam: hnyav oxidation ntawm lub taub hau electrode, kev sib cuag tsis zoo ntawm cov khoom siv vuam, txawm tias qhov hloov pauv tau teeb tsa siab dhau lawm.
Lub suab nrov los ntawm vuam AC contactor: seb qhov hluav taws xob tuaj ntawm AC contactor thaum vuam qis dua nws tus kheej tso tawm hluav taws xob los ntawm 300 volts.
Cov khoom siv overheats: xyuas cov dej nkag siab, dej ntws tus nqi, muab dej kub, seb cov dej txias puas raug thaiv.: leo@agerawelder.com
