Vim li cas Electrode Pressure tseem ceeb rau Medium Frequency Spot Vuam?

Nruab nrab zaus qhov chaw vuam yog cov txheej txheem siv dav hauv ntau qhov kev lag luam rau kev koom nrog cov khoom siv hlau. Ib qho tseem ceeb uas cuam tshuam rau qhov zoo thiab kev ntseeg siab ntawm cov welds yog cov electrode siab siv thaum lub sij hawm tus txheej txheem. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv qhov tseem ceeb ntawm electrode siab nyob rau hauv nruab nrab zaus qhov chaw vuam thiab yuav ua li cas nws cuam tshuam rau tag nrho cov txiaj ntsig weld.

Lub luag haujlwm ntawm Electrode Pressure:

Electrode siab yog hais txog lub zog quab yuam los ntawm cov electrodes ntawm lub workpieces raug welded. Lub siab no ua lub luag haujlwm tseem ceeb hauv kev ua tiav qhov sib koom ua ke uas muaj zog thiab zoo sib xws. Nov yog vim li cas electrode siab tseem ceeb heev:

1. Kev sib cuag ntawm cov khoom siv thiab kev tsim hluav taws xob:Kev siv hluav taws xob zoo ua kom pom kev sib cuag ntawm cov khoom ua haujlwm thiab cov electrodes. Qhov kev sib cuag no yog qhov tseem ceeb rau kev tsim hluav taws xob zoo thiab hloov pauv thaum lub sijhawm vuam. Kev tsis txaus siab tuaj yeem ua rau cov cua sov tsis zoo, ua rau cov welds tsis sib xws thiab muaj peev xwm ua tsis tau.
2. Hluav taws xob conductivity:Lub siab txaus pab tsim kom muaj hluav taws xob zoo ntawm cov electrodes thiab cov khoom ua haujlwm. Qhov no conductivity yog tsim nyog rau txoj kev tam sim no los ntawm cov hlau Cheebtsam, ua rau lub zos cua sov nyob rau hauv lub vuam cov ntsiab lus.
3. Molten Material Flow:Nyob rau hauv qhov chaw welding, ib feem ntawm cov hlau ntawm qhov vuam taw tes ua molten thiab ntws ua ke los tsim cov weld nugget. Txaus electrode siab ua kom zoo molten cov ntaub ntawv txaus thiab fusion, ua rau muaj zog weld sib koom ua ke.
4. Minimization ntawm Electrode Hnav:Qhov zoo tshaj plaws siab pab faib cov tam sim no thiab cua sov sib npaug, txo qhov kev pheej hmoo ntawm overheating thiab electrode hnav. Qhov no ua rau lub neej ntev ntawm cov electrodes thiab txo qhov kev xav tau ntawm kev hloov ntau zaus.

Kev cuam tshuam rau Weld Quality:

Cov qib ntawm electrode siab ncaj qha cuam tshuam qhov zoo ntawm cov vuam tsim. Kev tsis txaus siab tuaj yeem ua rau ntau qhov kev sib tsoo, suav nrog:

1. Weak Welds:Kev tsis txaus siab yuav ua rau tsis zoo fusion ntawm cov khoom ua haujlwm, ua rau tsis muaj zog welds uas ua rau tsis ua haujlwm hauv kev ntxhov siab.
2. Porosity:Lub siab tsis txaus tuaj yeem cuam tshuam cov huab cua los yog gases ntawm lub workpieces, ua rau porosity nyob rau hauv lub weld. Porosity tsis muaj zog ntawm qhov sib koom ua ke thiab ua rau nws raug corrosion thiab tawg.
3. Incomplete Penetration:Kev tsim nyog yog tsim nyog rau kev ua tiav kev nkag mus los ntawm cov ntawv hlau. Kev nkag mus tsis tiav tuaj yeem cuam tshuam qhov kev ncaj ncees ntawm cov vuam.

Nrhiav qhov zoo tshuav:

Thaum siab dua electrode feem ntau ua rau zoo dua weld zoo, siab dhau kuj tuaj yeem muaj qhov tsis zoo. Nws yuav ua rau cov khoom deformation, hnav electrode ntau dhau, thiab txawm tias cov hlau molten tawm ntawm qhov chaw vuam. Yog li ntawd, nrhiav qhov sib npaug yog qhov tseem ceeb.

electrode siab yog ib qho tseem ceeb parameter nyob rau hauv nruab nrab zaus qhov chaw vuam. Nws cuam tshuam rau ntau yam ntawm cov txheej txheem vuam, los ntawm kev tsim hluav taws xob mus rau cov khoom ntws thiab tag nrho cov vuam zoo. Cov neeg ua haujlwm vuam yuav tsum ua tib zoo kho thiab saib xyuas cov electrode siab kom ua tau raws li qhov sib xws thiab txhim khu kev qha welds, kom ntseeg tau qhov kev ncaj ncees ntawm cov khoom kawg.
