Preloading, tseem hu ua precompression lossis pre-squeeze, yog ib qho tseem ceeb hauv cov txheej txheem ntawm nruab nrab zaus inverter chaw vuam.Kab lus no tshawb txog qhov tseem ceeb ntawm preloading thiab nws cuam tshuam rau weld zoo thiab kev ua tau zoo.
Ua kom zoo Electrode Alignment:
Ib lub hom phiaj tseem ceeb ntawm preloading yog los xyuas kom meej qhov zoo ntawm cov electrodes ua ntej qhov tseeb vuam txheej txheem pib.Los ntawm kev siv lub zog tswj preloading, cov electrodes raug coj mus rau hauv kev sib cuag nrog cov workpieces, tsim kom muaj kev ruaj khov thiab zoo ib yam electrode-rau-workpiece interface.Qhov kev sib raug zoo no yog qhov tseem ceeb rau kev tswj xyuas qhov sib xws tam sim no thiab kev faib hluav taws xob thaum lub sij hawm vuam, ua rau muaj kev ntseeg siab thiab sib xws.
Txhim kho hluav taws xob conductivity:
Preloading pab txhim kho cov hluav taws xob conductivity ntawm electrodes thiab workpieces.Los ntawm kev siv lub siab, txhua yam kab mob los yog oxides uas tuaj yeem cuam tshuam cov hluav taws xob tiv tauj tau raug tshem tawm lossis tawg, ua rau kom zoo dua tam sim no.Txhim kho hluav taws xob conductivity txhawb kev hloov hluav taws xob zoo, ua rau muaj txiaj ntsig zoo dua thiab muaj zog welds.
Ua kom muaj kev sib txuam Nugget:
Daim ntawv thov ntawm preloading quab yuam pab kom tsim tau ib tug zoo ib yam thiab zoo-txhais weld nugget.Lub preload compresses lub workpieces, txo qhov kev tiv thaiv tiv thaiv thiab ua kom muaj cua sov zoo dua ntawm lub interface.Qhov kev tswj xyuas compression no pab txhawb kev tsim ntawm thaj chaw fusion txhim khu kev qha, uas muaj kev sib raug zoo thiab kev sib raug zoo ntawm metallurgical.
Tsawg Electrode Marks:
Preloading tuaj yeem txo qhov tsim ntawm cov cim electrode ntawm qhov chaw ua haujlwm.Thaum cov electrodes raug preloaded kom zoo, lub siab yog tusyees faib, txo qhov kev pheej hmoo ntawm lub zos indentation los yog cim los ntawm kev quab yuam ntau dhau.Qhov no yuav pab khaws cia qhov zoo nkauj ntawm cov khoom siv welded.
Txhawb Weld Strength thiab Durability:
Daim ntawv thov ntawm preloading quab yuam txhawb lub zuag qhia tag nrho lub zog thiab durability ntawm qhov chaw weld.Los ntawm kev ua kom muaj kev sib raug zoo, hluav taws xob conductivity, thiab tsim nugget, preloading pab txhawb rau welds nrog txhim kho cov khoom siv, xws li siab dua tensile thiab shear zog.Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas muaj kev ncaj ncees thiab kev ua haujlwm ntev yog qhov tseem ceeb.
Preloading plays lub luag haujlwm tseem ceeb hauv nruab nrab zaus inverter chaw vuam.Nws ua kom muaj kev sib raug zoo ntawm electrode, txhim kho cov hluav taws xob conductivity, txhawb kev tsim cov txiaj ntsig zoo ib yam, txo cov cim electrode, thiab txhawb nqa lub zog thiab ua haujlwm ntev.Los ntawm kev koom ua ke preloading raws li tus qauv kev coj ua, cov neeg ua haujlwm tuaj yeem ua tiav qhov chaw welds zoo nrog kev txhim kho kev ntseeg siab, cov khoom siv kho tshuab, thiab kev ua haujlwm tag nrho.
