Preloading thiab tuav yog cov kauj ruam tseem ceeb hauv kev ua haujlwm ntawm nruab nrab zaus inverter chaw vuam tshuab. Cov txheej txheem no yog siv los xyuas kom meej kev sib cuag ntawm cov electrodes thiab workpieces, nrog rau kev tswj lub siab xav tau thaum lub vuam txheej txheem. Kab lus no muab cov ntsiab lus ntawm preloading thiab tuav hauv nruab nrab zaus inverter chaw vuam tshuab.
- Preloading: Preloading yog hais txog thawj daim ntawv thov ntawm lub siab ntawm lub workpieces ua ntej siv vuam tam sim no. Nws ua haujlwm rau ntau lub hom phiaj, suav nrog:
- Ua kom muaj kev sib cuag electrode-rau-workpiece los ntawm kev tshem tawm cov huab cua tsis sib xws lossis qhov tsis sib xws.
- Stabilizing lub workpieces thiab tiv thaiv kev txav thaum vuam.
- Txo qhov tsis kam ntawm qhov kev sib cuag, ua rau muaj kev txhim kho tam sim no thiab tsim hluav taws xob.
- Tuav: Tuav, tseem hu ua tom qab vuam siab, yog kev saib xyuas lub siab ntawm cov khoom ua haujlwm tom qab lub vuam tam sim no raug kaw. Nws tso cai rau lub sij hawm txaus rau lub weld nugget kom solidify thiab tsim ib tug muaj zog daim ntawv cog lus. Qhov tseem ceeb ntawm kev tuav pov hwm muaj xws li:
- Siv lub zog tswj thiab sib xws rau qhov chaw vuam.
- Tiv thaiv kev sib cais ntxov ntxov ntawm lub workpieces ua ntej weld solidifies.
- Tso cai rau kom txaus cua sov dissipation kom txo qis distortion los yog overheating.
- Qhov tseem ceeb ntawm Preloading thiab Tuav: Preloading thiab tuav yog ib qho tseem ceeb rau kev ua tiav qhov chaw zoo welds. Lawv muab cov txiaj ntsig hauv qab no:
- Txhim kho weld zoo ib yam thiab rov ua dua los ntawm kev ua kom lub siab sib xws thiab kev sib cuag electrode.
- Txhim kho cua sov faib thiab fusion ntawm workpieces.
- Tsawg tsim ntawm qhov tsis xws luag, xws li voids lossis tsis tiav kev nkag mus.
- Ua kom muaj zog sib koom ua ke thiab durability.
- Preloading thiab Holding Techniques: Cov txheej txheem sib txawv tuaj yeem ua haujlwm rau preloading thiab tuav, nyob ntawm seb qhov tshwj xeeb ntawm daim ntawv thov vuam. Qee txoj hauv kev uas muaj xws li:
- Mechanical caij nplooj ntoos hlav-loaded tshuab uas muab lub siab tsis tu ncua thoob plaws hauv lub voj voog vuam.
- Pneumatic los yog hydraulic tshuab uas tuaj yeem hloov kho kom xa cov siab thiab zoo ib yam.
- Programmable tswj systems uas tso cai rau customized preloading thiab tuav sequences raws li nyob rau hauv workpiece cov ntaub ntawv thiab thickness.
Preloading thiab tuav yog cov kauj ruam tseem ceeb hauv kev ua haujlwm ntawm nruab nrab zaus inverter chaw vuam tshuab. Lawv xyuas kom zoo electrode-rau-workpiece kev sib cuag, stabilize lub workpieces thaum lub sij hawm vuam, thiab pab tsim kom muaj zog thiab zoo welds. Los ntawm kev nkag siab txog qhov tseem ceeb ntawm preloading thiab tuav thiab siv cov txheej txheem tsim nyog, cov neeg ua haujlwm tuaj yeem txhim kho qhov zoo, kev ntseeg tau, thiab kev ua tau zoo ntawm qhov chaw welds hauv ntau daim ntawv thov kev lag luam.
