I-Resistance spot welding yindlela esetyenziswa ngokubanzi kwiinkqubo zokuvelisa, ngakumbi kwimizi-mveliso yeemoto kunye ne-aerospace. Le ndlela ibandakanya ukudibanisa iziqwenga ezimbini zetsimbi kunye ngokusebenzisa ubushushu kunye noxinzelelo ngokusebenzisa i-electrode. Enye iparameter ebalulekileyo kule nkqubo kuxinzelelo lwe-electrode. Kweli nqaku, siza kuhlolisisa ukubaluleka koxinzelelo lwe-electrode kumatshini wokuwelda indawo yokumelana kunye nefuthe lawo kumgangatho wee-welds.
Ukuqonda uxinzelelo lwe-Electrode
Uxinzelelo lwe-electrode, nokwaziwa njengamandla e-welding okanye uxinzelelo loqhagamshelwano, lubhekisa kumandla asetyenziswa zii-electrode zokuwelda kwizinto zokusebenza ezidityaniswayo. Olu xinzelelo ludlala indima ebalulekileyo ekuqinisekiseni i-weld eyimpumelelo. Imisebenzi ephambili yoxinzelelo lwe-electrode yile:
1. Ukuqinisekisa uQhagamshelwano oluLungileyo loMbane
Ukuze i-welding yendawo yokumelana esebenzayo, indlela yombane enganyangekiyo kufuneka ibe khona phakathi kwee-electrode kunye nezinto zokusebenza. Uxinzelelo olwaneleyo luqinisekisa ukudibanisa kakuhle kombane, ukunciphisa ukunyanzeliswa kombane kunye nokuvumela ukuhamba kwe-welding yangoku ngokudibeneyo. Oku, kwakhona, kuququzelela ukuveliswa kobushushu obufunekayo kwinkqubo ye-welding.
2. Ukukhuthaza ukuguqulwa kwezinto
Uxinzelelo olwenziwa yi-electrodes lubangela ukuguqulwa kwendawo kwindawo yokusebenza. Olu tshintsho ludala unxibelelwano olusondeleyo phakathi kwezinto ezimbini zokusebenza, ukwandisa ibhondi ye-metallurgical ngexesha le-welding. Ikwanceda ekugqobhozeni ungcoliseko olungaphezulu olufana neeoksidi kunye neengubo zokwaleka, nokuphucula umgangatho we weld.
3. Ukulawula isiZukulwana soBubushushu
Uxinzelelo olufanelekileyo lwe-electrode lunceda ukulawula ubungakanani bobushushu obuveliswa ngexesha le-welding. Uxinzelelo olugqithisileyo lunokukhokelela ekufudumeni, ngelixa uxinzelelo olungonelanga lunokubangela ukuveliswa kobushushu obunganelanga. Ukufezekisa ulungelelwaniso olufanelekileyo kubalulekile ukukhusela umonakalo kwizinto zokusebenza kunye nokuqinisekisa i-weld eyomeleleyo.
Uxinzelelo lwe-Electrode oluLungileyo
Ukumisela uxinzelelo lwe-electrode olufanelekileyo kuxhomekeke kwizinto ezahlukeneyo, kubandakanya izinto ezidityanisiweyo, ubukhulu bayo, kunye ne-welding yangoku. Abavelisi bahlala bebonelela ngezikhokelo kunye neenkcukacha zoxinzelelo lwe-electrode ngokusekelwe kule miba. Ukongeza, abaqhubi be-weld banokubeka iliso kwaye bahlengahlengise uxinzelelo lwe-electrode ukufezekisa umgangatho ofunekayo we-weld.
Impembelelo kuMgangatho weWeld
Uxinzelelo lwe-electrode olungonelanga lunokukhokelela kwiziphene ezininzi ze-welding, ezinje nge-fusion engaphelelanga, i-porosity, kunye ne-weld bonds ebuthathaka. Ngakolunye uhlangothi, uxinzelelo olugqithisileyo lunokubangela ukugqithiswa kwe-welding, kubangele i-deformation kunye nomonakalo kwizinto zokusebenza. Ngoko ke, ukugcina uxinzelelo oluchanekileyo lwe-electrode lubalulekile ekuveliseni i-welds ephezulu kunye neempawu ezifunwayo zoomatshini.
Kumatshini wokuwelda indawo yokumelana, uxinzelelo lwe-electrode yiparamitha ephambili echaphazela kakhulu umgangatho wee-welds. Iqinisekisa ukudibana kombane okulungileyo, ikhuthaza ukuguqulwa kwezinto eziphathekayo, kwaye ilawula ukuveliswa kobushushu. Ukufezekisa iziphumo ezizezona zilungileyo, kubalulekile ukuqonda imathiriyeli edityanisiweyo kwaye ulandele izikhokelo zoxinzelelo lwe-electrode. Ulawulo olufanelekileyo loxinzelelo lwe-electrode aluyi kwandisa kuphela umgangatho we-weld kodwa kwakhona negalelo ekusebenzeni kakuhle kunye nokuthembeka kwenkqubo ye-welding.
