Xa usebenzisa i-medium frequency inverter spot welder ukuwelda iipleyiti zensimbi ezingenasici, kuqhelekile ukudibana nengxaki ye-porosity.I-Porosity ibhekiselele kubukho beepokotho ezincinci zomoya okanye i-voids ngaphakathi kwentsimbi ye-weld, enokuthi yenze buthathaka amandla onke e-weld kwaye ibangele iziphene.
Kukho izizathu ezininzi zokuba kutheni i-porosity inokuthi yenzeke xa iwelding intsimbi engenasici kunye ne-medium frequency inverter spot welder.Enye yezinto eziphambili kubukho bezinto ezingcolileyo kumphezulu wesinyithi, njengeoli, igrisi, okanye irusi.Ezi zingcolisi zingenza iipokotho zegesi ngexesha lenkqubo ye-welding, ekhokelela kwi-porosity.
Enye inkalo ye-welding parameters.Ukuba i-welding current okanye i-pressure iphezulu kakhulu, inokudala ubushushu obugqithisileyo kwaye ibangele ukuba isinyithi sibe ngumphunga, okukhokelela kwiipokotho zegesi kunye ne-porosity.Ngokufanayo, ukuba isantya se-welding sikhawuleza kakhulu, sinokungavumeli ixesha elaneleyo lokuba isinyithi sidibanise ngokufanelekileyo kunye, okubangela ukuba i-welds ingaphelelanga kunye ne-porosity.
Ukuthintela i-porosity xa i-welding steel stainless nge-medium frequency inverter spot welder, kubalulekile ukulungiselela ngokufanelekileyo umphezulu wesinyithi ngokuyicoca kuyo nayiphi na into engcolileyo.Ukongezelela, kubalulekile ukulungelelanisa ngokucophelela iiparitha ze-welding ukuqinisekisa ukuba ziphakathi koluhlu olufanelekileyo lwesicelo esithile.
Ngamafutshane, i-porosity xa i-welding insimbi engenasici kunye ne-medium frequency inverter spot welder ingenzeka ngenxa yokungcoliswa komphezulu okanye imilinganiselo ye-welding engafanelekanga.Ngokuthatha amanyathelo afanelekileyo ukulungiselela isinyithi kunye nokulungelelanisa iiparitha ze-welding, kunokwenzeka ukuba ufezekise umgangatho ophezulu, i-porosity-free welds.
