Ib tug loj npaum li cas ntawm cov huab cua nkag mus rau hauv cov roj yuav ua rau aggravate lub" cavitation" phenomenon, ua kom lub compressibility ntawm cov roj hydraulic, ua hauj lwm instability, txo kev ua hauj lwm efficiency, thiab ua rau" nkag" ntawm cov actuators. Tsis tas li ntawd, huab cua kuj tseem yuav oxidize cov roj hydraulic thiab ua kom cov roj tsis zoo.
Thaum lub sij hawm vuam, vim muaj kev sib xyaw ua ke ntawm thermal load thiab mechanical load ntawm lub electrode cap, oxide zaj duab xis los yog roj thiab lwm yam impurities yuav raug tsim nyob rau saum npoo ntawm electrode raws li tus naj npawb ntawm qhov chaw vuam nce. Nws yog precisely cov khoom no ncaj qha cuam tshuam qhov ceev ntawm vuam tam sim no.
Cov hluav taws xob conductivity thiab thermal conductivity ntawm cov khoom siv electrode yog ncaj qha cuam tshuam rau tiam thiab poob ntawm cov cua sov, yog li cov duab thiab cov khoom siv ntawm electrode muaj feem cuam tshuam rau lub nugget. Raws li cov lus qhia electrode siv, qhov saum npoo ntawm lub workpiece yuav maj mam hnav thiab deform, uas yuav yog li ntawd, qhov chaw sib cuag tau nce, lub zog ntawm cov khoom sib koom ua ke tsis ruaj khov, thiab cov nplai oxide thiab roj rau ntawm qhov chaw. workpiece yuav ncaj qha nce kev tiv thaiv.
Vim hais tias cov tuab nruab nrab yuav ua kom cov Vuam tam sim no tsis tau dhau, thiab ntev li tam sim no ceev yuav ua rau loj nto hlawv thiab muaj txaws, yog li tu qhov chaw ntawm lub workpiece ua ntej lub weld yog tus mob thawj rau muab high-zoo solder pob qij txha.
