Xa uwelda iipleyiti zentsimbi engenaziphene ezineendawo zokuwelda zamaxesha aphakathi, i-porosity inokuba ngumcimbi oqhelekileyo.I-Porosity ibhekisela kubukho bemibhobho encinci okanye imingxuma kwi-joint welded, enokuthi ibe buthathaka ngokubambisana kunye nokunciphisa umgangatho wayo wonke.Kweli nqaku, siza kuxubusha ezinye iindlela zokusombulula ingxaki ye-porosity kwi-welding steel stainless steel plates kunye ne-intermediate frequency spot welders.
Okokuqala, kubalulekile ukuqinisekisa ukuba izixhobo zokuwelda zisekwe ngokuchanekileyo.Oku kubandakanya ukukhetha iiparamitha ezifanelekileyo ze-welding ezifana ne-welding current, ixesha le-welding, amandla e-electrode, kunye nobukhulu be-electrode.Ukusebenzisa iiparitha ezingalunganga kunokukhokelela kwi-porosity kunye nezinye iziphene kwi-joint welded.
Okwesibini, i-welding surface ye-stainless steel plates kufuneka ihlambuluke ngokufanelekileyo kwaye ilungiswe ngaphambi kokuba i-welding.Naziphi na izinto ezingcolisayo ezifana nomhlwa, ioyile, okanye igrisi kufuneka zisuswe ukuze kuqinisekiswe indawo ecocekileyo negudileyo yokuwelda.Oku kunokufumaneka ngokusebenzisa izinyibilikisi, iibrashi zocingo, okanye ezinye izixhobo zokucoca.
Okwesithathu, ukusebenzisa indlela efanelekileyo yokuwelda kubalulekile ekuthinteleni i-porosity.Ngokomzekelo, ukugcina isantya esifanelekileyo se-welding, ukulawula amandla e-electrode kunye ne-angle, kunye nokuqinisekisa ukulungelelaniswa okufanelekileyo phakathi kwee-electrodes kunye ne-workpiece kunokunceda ukukhusela i-porosity ukuba ingenzeki.
Ukongeza, ukukhetha izinto ezisetyenziselwa ukuwelda ezifanelekileyo kunokunceda ukukhusela i-porosity.Kwi-welding steel stainless, kucetyiswa ukuba kusetyenziswe iingcingo ze-welding okanye i-electrode enomxholo ophantsi wekhabhoni ukunciphisa umngcipheko we-porosity.
Ekugqibeleni, ukuba i-porosity isenzeka emva kokuphumeza le miqathango, kunokufuneka ukuba uhlolisise kwaye ulungelelanise izixhobo ze-welding okanye ufune iingcebiso zengcali ye-welding ukuchonga nokusombulula nayiphi na imiba engaphantsi.
Ukuqukumbela, i-porosity ngumba oqhelekileyo xa udibanisa iipleyiti zensimbi ezingenasici kunye ne-intermediate frequency spot welders, kodwa inokuthintelwa ngokuqinisekisa ukuseta izixhobo ezifanelekileyo, ukulungiswa komphezulu, ubuchule bokuwelda, kunye nokukhethwa kwe-welding consumable.Ukuba i-porosity isenzeka, ukuhlolwa okungaphezulu kunye nohlengahlengiso kunokufuneka ukusombulula umba.
