Uma usebenzisa i-medium frequency inverter spot welder ukushisela amapuleti ensimbi engagqwali, kuvamile ukuhlangana nenkinga ye-porosity.I-Porosity isho ukuba khona kwamaphakethe omoya amancane noma ama-voids ngaphakathi kwensimbi yokushisela, engenza buthaka wonke amandla e-weld futhi kubangele ukukhubazeka.
Kunezizathu ezimbalwa zokuthi kungani i-porosity ingase yenzeke lapho kushiselwa insimbi engagqwali nge-medium frequency inverter spot welder.Esinye sezici eziyinhloko ukuba khona kokungcola ebusweni bensimbi, njengamafutha, amafutha, noma ukugqwala.Lokhu kungcola kungakha amaphakethe egesi ngesikhathi senqubo yokushisela, okuholela ku-porosity.
Esinye isici amapharamitha we-welding.Uma i-welding current noma ingcindezi iphezulu kakhulu, ingadala ukushisa okudlulele futhi ibangele ukuba insimbi ihwamuke, okuholela emaphaketheni egesi kanye ne-porosity.Ngokufanayo, uma isivinini sokushisela sishesha kakhulu, singase singavumeli isikhathi esanele sokuthi insimbi ihlangane kahle, okuholela ekushiseleni okungaphelele kanye ne-porosity.
Ukuvimbela i-porosity lapho ushisela insimbi engagqwali nge-medium frequency inverter spot welder, kubalulekile ukulungisa kahle indawo yensimbi ngokuyihlanza kunoma yikuphi ukungcola.Ukwengeza, kubalulekile ukulungisa ngokucophelela imingcele ye-welding ukuqinisekisa ukuthi ingaphakathi kwebanga elifanele lesicelo esithile.
Kafushane, i-porosity lapho kushiselwa insimbi engagqwali nge-medium frequency inverter spot welder kungenzeka ngenxa yokungcola okungaphezulu noma imingcele ye-welding engafanele.Ngokuthatha izinyathelo ezifanele zokulungiselela insimbi futhi ulungise imingcele ye-welding, kungenzeka ukufeza izinga eliphezulu, ama-welds angenayo i-porosity.
