Introduction to the Formation Principple of Weld Spots in Medium-Frequency Inverter Spot Vuam Tshuab

Nyob rau hauv nruab nrab-zaus inverter chaw vuam tshuab, tsim ntawm weld me ntsis yog txheej txheem tseem ceeb uas txiav txim siab qhov zoo thiab lub zog ntawm cov pob qij txha. To taub lub hauv paus ntsiab lus tom qab weld chaw tsim yog qhov tseem ceeb rau optimizing welding tsis thiab ua tiav cov welds txhim khu kev qha thiab zoo ib yam. Kab lus no muab cov ntsiab lus ntawm kev tsim cov hauv paus ntsiab lus ntawm weld me ntsis hauv nruab nrab zaus inverter qhov chaw vuam tshuab, tso lub teeb rau ntawm qhov tseem ceeb ntawm cov txheej txheem.

1. Hluav taws xob tiv thaiv cua sov: Kev tsim cov chaw vuam hauv nruab nrab zaus inverter qhov chaw vuam tshuab feem ntau yog nyob ntawm cov hluav taws xob tiv thaiv cua sov. Thaum lub vuam tam sim no dhau los ntawm cov khoom ua haujlwm yuav tsum tau koom nrog, cov hluav taws xob tiv thaiv ntawm qhov chaw sib cuag ua kom sov. Qhov cua sov hauv cheeb tsam no ua rau cov hlau ntawm qhov sib cuam tshuam kom ncav cuag nws qhov melting point, uas ua rau tsim lub pas dej molten.
2. Kev Siv Siab: Ib txhij nrog cov hluav taws xob tiv thaiv cua sov, lub siab yog siv rau cov khoom ua haujlwm los ntawm cov lus qhia electrode. Lub siab pab ua kom muaj kev sib raug zoo ntawm cov khoom ua haujlwm, ua kom yooj yim rau kev hloov cov cua sov thiab cov hlau fusion. Nws kuj txhawb kev tshem tawm ntawm impurities thiab oxides los ntawm thaj chaw weld, tso cai rau kom muaj kev ruaj ntseg thiab ruaj khov.
3. Solidification thiab Fusion: Raws li cov hluav taws xob tiv thaiv cua sov thiab siab tswj, cov hlau molten nyob rau hauv lub pas dej weld pib solidify. Cov txheej txheem txias thiab solidification ua rau cov hlau molten hloov mus rau hauv lub xeev ruaj khov, tsim cov hlau sib txuas ntawm cov khoom ua haujlwm. Lub solidification thiab fusion ntawm cov hlau molten tsim muaj zog thiab ruaj khov weld sib koom ua ke.
4. Weld Spot Formation Factors: Muaj ntau yam cuam tshuam rau kev tsim cov chaw vuam hauv nruab nrab zaus inverter qhov chaw vuam tshuab. Cov yam tseem ceeb no suav nrog lub vuam tam sim no, lub sijhawm vuam, lub zog hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv ua haujlwm, thiab cov xwm txheej saum npoo. Kev tswj kom zoo ntawm cov kev ntsuas no yog qhov tseem ceeb heev kom ua tiav qhov sib txuas ntawm qhov chaw tsim thiab ua kom ntseeg tau qhov xav tau weld zoo.

Kev tsim cov chaw vuam hauv nruab nrab zaus inverter qhov chaw vuam tshuab tso siab rau cov qauv ntawm cov hluav taws xob tiv thaiv cua sov, kev siv siab, thiab kev sib zog. Kev nkag siab txog cov yam tseem ceeb uas cuam tshuam rau kev tsim cov khoom siv vuam tso cai rau cov tswv lag luam kom ua kom zoo dua cov vuam tsis zoo thiab ua kom ntseeg tau thiab ua tau zoo welds. Los ntawm kev tswj tsis tau xws li vuam tam sim no, lub sij hawm, electrode quab yuam, thiab cov khoom xaiv, cov neeg siv tuaj yeem ua tau raws li qhov sib xws thiab txaus siab weld qhov chaw tsim, ua rau muaj zog thiab ruaj khov weld pob qij txha.
