Kuwo wonke umsebenzi we-welding, incam ye-electrode yinxalenye ebalulekileyo apho onke amandla e-welding ahanjiswa. Ngokuhamba kwexesha, ubushushu obuphezulu, uxinzelelo, kunye nokuhanjiswa kwezinto kubangela ukuba incam ye-electrode igqweke, ijikelezwe, okanye ingcoliseke. Kwimveliso yangoku{2}}ingakumbi ngokwamkelwa ngokubanzi kweumatshini wokuwelda indawo-imeko ye-electrode ibaluleka ngakumbi.
Ukunxitywa rhoqo kwe-electrode yenye yezona ndlela zilula kodwa zisebenzayo zokugcina umgangatho we-weld ozinzile kunye nokunciphisa iindleko zemveliso.
Iziphumo zeElectrode Wear
Xa incam ye-electrode igugile, iphosakele, okanye ingalingani, kuvela imiba emininzi:
- Usasazo olungalinganiyo lwangoku
- Ukonyuka kwesitshizi kunye nokutsha komphezulu
- I-weld nuggets ebuthathaka okanye engahambelaniyo
- Ukuthotywa kwe-electrode ngokukhawuleza
- Iindleko eziphezulu zemveliso kwaye zisezantsi kuqala{0}}isivuno sokudlula
Kwiifektri ezininzi ezisebenzisa iinkqubo ze-welding ze-MFDC, ukutsiba ukugcinwa kwe-electrode kudla ngokukhokelela kumgangatho we-weld ongazinzanga. Abanye abavelisi baxela ukuhla kwe-20% kwireyithi yokupasa kwemveliso xa ukunxitywa kwe-electrode kungahoywa.
Izizathu ezithathu ezingundoqo zokuba kutheni ukunxiba rhoqo kuyimfuneko
Gcina iMfitya yoMphezulu ukwenzela ukuHamba okuZinzileyo kwangoku
Incam ye-electrode egugileyo okanye ephothiweyo ibangela ukuxhathisa kombane ukwahluka kwiindawo ezahlukeneyo. Oku kugxininisa okwangoku kwiindawo eziphezulu, okukhokelela ekufudumeni, ukutshiza, okanye ukwakheka kwe-nugget eyaneleyo.
Ukunxitywa rhoqo kubuyisela umgangatho wokudibanisa ogudileyo, olinganayo, oqinisekisa ukuhamba kwangoku kunye nomgangatho we-weld ongaguqukiyo.
Yandisa i-Electrode Lifespan kunye nokunciphisa iFrequency Replacement
Ukunxitywa kwesiqhelo kususa kuphela umaleko womhlaba owonakeleyo, ukuthintela ukunxiba okugqithisileyo.
Idatha yeShishini ibonisa ukuba ngokulungiswa okufanelekileyo, abavelisi abasebenzisa i-MFDC spot welders banokwandisa ubomi be-electrodeukuya kuthi ga kwi-30%, ukunciphisa ixesha lokuphumla kunye neendleko zokubuyisela.
Ukuphucula umgangatho we-Weld Nugget kwaye unciphise i-Spatter
I-electrode enxibe ngokufanelekileyo ihambisa uxinzelelo oluzinzileyo loqhagamshelwano kunye noxinzelelo lwangoku.
Oku kuvelisa:
- Coca imiphezulu ye weld
- I-uniform weld nuggets
- Isitshizi esincinci
- Ukuhambelana kwemveliso ephezulu
Iiwelder ze-MFDC zinamandla okulawula achanekileyo, kodwa zifikelela kuphela ekusebenzeni kwazo ngokupheleleyo xa i-electrode igcinwa kwimeko efanelekileyo.
IiNdlela eziGqwesileyo zokuNxitywa kwe-Electrode
Iindlela ezicetyiswayo
- Sebenzisa izixhobo zokunxiba ze-electrode zobuchwephesha ukuze ufumane ezona ziphumo zichanekileyo kunye ne-symmetrical
- I-sandpaper entle (i-400–600 grit) ingasetyenziselwa ukunxitywa kwezandla okungxamisekileyo
- Susa i-oxides engaphezulu, imingxuma, kunye nezinto eziqhotyoshelweyo emva kokunxiba
Imilinganiselo yeNcam ye-Electrode ecetyiswayo
Emva kokunxiba, ububanzi bobuso be-electrode kufuneka bube ngamaxesha angama-3-5 ubukhulu bezinto ezidityanisiweyo.
Lo mlinganiselo ubonwa ngokubanzi njenge parameter engundoqo ekufezekiseni uzinzo,-umgangatho ophezulu we welds.
IziKhokelo eziSebenzayo zeMFDC Spot Welding Abasebenzisi
- Ukuseka ishedyuli yesiqhelo yokunxiba i-electrode
