Ukuqulunqwa kweZisombululo zePorosity kwiNut Projection Welding

I-Porosity ngumba oqhelekileyo ofunyanwa kwi-welding ye-nut projection welding, ekhokelela kwii-welds ezibuthathaka nezingathembekiyo. Kweli nqaku, siza kubonelela ngombono obanzi wezisombululo ezahlukeneyo zokujongana ne-porosity kwi-welding nut projection welding. Ngokuphumeza obu buchule, abaqhubi banokunciphisa ukwenzeka kwe-porosity kwaye baqinisekise i-welds eqinile.

1. Ukulungiswa komphezulu: Ukulungiswa okufanelekileyo komphezulu kubalulekile ukunciphisa i-porosity kwi-welding ye-nut projection welding. Phambi kwewelding, kubalulekile ukucoca ngokucokisekileyo iindawo zokukhwelana ze nut kunye ne workpiece ukususa naziphi na izinto ezingcolisayo, ezinje ngeoyile, ubumdaka, okanye ioksidi. Oku kunokufezekiswa ngokucoca i-solvent, ibrashi yocingo, okanye ukuqhushumba kwe-abrasive. Umphezulu ococekileyo ukhuthaza ukungena kwe-weld engcono kwaye unciphise umngcipheko wokwakheka kwe-porosity.
2. Ukukhetha i-Electrode: Ukukhethwa kwee-electrode ze-welding kunokuchaphazela kakhulu ukubunjwa kwe-porosity. Kunconywa ukusebenzisa i-electrodes eyenziwe ngezinto eziphathekayo ezinombane ophezulu kunye ne-reactivity ephantsi, ezifana nobhedu okanye i-alloys zethusi. Ezi electrode zibonelela ngokugqithiswa kobushushu obungcono kwaye zinciphise amathuba okubanjwa kwegesi, ukunciphisa ukubunjwa kwe-porosity.
3. Ukuphuculwa kweeParameters ze-Welding: Ukuphucula i-welding parameters kubalulekile ukunciphisa i-porosity. Iiparamitha ezifana ne-welding yangoku, ixesha, kunye noxinzelelo kufuneka zilungiswe ngononophelo ukuze kuphunyezwe umgangatho we-weld. I-welding yangoku okanye ixesha elinganelanga le-welding linokubangela ukuveliswa kobushushu okwaneleyo, okukhokelela kwi-porosity. Ngokwahlukileyo, i-welding egqithisileyo yangoku okanye ixesha elide le-welding inokudala ukushisa okugqithisileyo, ukukhupha izinto kunye nokubangela i-porosity. Ukufumana ibhalansi efanelekileyo ngundoqo ekunciphiseni i-porosity.
4. Ukukhusela igesi: Kwezinye iimeko, ukusetyenziswa kweegesi zokukhusela kunokuncedisa ukunciphisa i-porosity. Iigesi ezikhuselayo, ezifana ne-argon okanye i-helium, zenza indawo yokukhusela ejikeleze indawo ye-weld, ukukhusela ukungena kweegesi ze-atmospheric ezinokuthi zibe negalelo kwi-porosity. Oku kuluncedo ngakumbi xa uwelda izinto ezisebenzayo okanye kwindawo enamanqanaba aphezulu ongcoliseko lomoya.
5. Ukugcinwa kwe-Electrode: Ukugcinwa rhoqo kwee-electrode ze-welding kubalulekile ukukhusela i-porosity. Ngokuhamba kwexesha, ii-electrode zinokungcoliseka okanye ziguge, nto leyo ekhokelela ekugqithiseni ubushushu obuphantsi kunye nokunyuka kwe-porosity. Kubalulekile ukucoca kunye nokuhlola i-electrodes rhoqo, ukususa nayiphi na into engcolileyo eyakhelweyo okanye i-oxidation. Ukongezelela, ukutshintshwa kwee-electrodes ezigugileyo kuqinisekisa ukusebenza okufanayo kunye nokunciphisa umngcipheko we-porosity.
6. I-Welding Technique: Indlela efanelekileyo ye-welding idlala indima ebalulekileyo ekunciphiseni i-porosity. Abaqhubi kufuneka baqinisekise ukulungelelaniswa okulungileyo phakathi kwe-nut kunye ne-workpiece, bagcine uxinzelelo oluzinzile ngexesha lokudibanisa, kwaye ugweme amandla amaninzi e-electrode okanye ukunyakaza ngokukhawuleza. Ubuchwephesha be-welding obuhambelanayo kunye nokulawulwayo bunceda ukunciphisa i-porosity kunye nokuvelisa i-welds ezikumgangatho ophezulu.

I-Porosity kwi-welding nut projection welding inokuphazamisa ingqibelelo kunye namandla e-welds. Nangona kunjalo, ngokulandela izisombululo ezichazwe kweli nqaku, abaqhubi banokunciphisa ngokufanelekileyo imiba ye-porosity. Ukuphumeza ukulungiswa okufanelekileyo komphezulu, ukukhetha i-electrodes efanelekileyo, ukulungelelanisa imilinganiselo ye-welding, ukusebenzisa i-gas shielding, ukugcina i-electrodes, kunye nokusetyenziswa kobuchule obufanelekileyo be-welding ngamanyathelo abalulekileyo okunciphisa i-porosity kunye nokufezekisa i-welds eqinile kunye ethembekileyo kwizicelo ze-welding ze-nut.
