Kwimveliso yemizi-mveliso,{0}}ukuphindaphinda okuphakathioomatshini bokuwelda amabalazixatyiswe ngokusebenza kwazo kunye nokonga amandla. Nangona kunjalo, ukunxiba ngokukhawuleza kwe-electrode ngumngeni oqhelekileyo ochaphazela ngokuthe ngqo umgangatho we-weld, imveliso, kunye neendleko zokusebenza. Eli nqaku libonelela ngohlalutyo olucwangcisiweyo lwezizathu ezisisiseko zokunxiba i-electrode kwaye linikezela ngezisombululo ezisebenzayo zokwandisa ubomi bezixhobo.
Ayilunganga iSetingi yangoku kunye noxinzelelo
Ibhalansi phakathi kwe-welding yangoku kunye namandla e-electrode yeyona nto iphambili echaphazela ukunxiba. Imimiselo engafanelekanga inokukhawuleza ukuthothisa i-electrodes.
Ngokugqithisileyo ngoku:Ubuninzi bangoku bubangela ukugqithisa ngokukhawuleza kwincam ye-electrode, ekhokelela ekuthobeni, ukuguqulwa, kunye "ne-mushrooming."
Uxinzelelo olungonelanga:Amandla aphantsi abangela ukudibana kakubi, ukwandisa ukuxhathisa kombane kunye nokugxila kubushushu kwincam ye-electrode endaweni yeendawo zokusebenza, okubangela ukugoba nokuncamathela.
Izisombululo:
Iiparamitha ezichanekileyo:Seta yangoku ngokusekwe kudidi lwemathiriyeli kunye nobukhulu (umzekelo, 8-12 kA/mm² yentsimbi ephakathi; ephezulu kwialuminiyam).
Yandisa amandla:Gcina uxinzelelo lwe-electrode ngaphakathi koluhlu olucetyiswayo (umzekelo, i-0.2-0.4 MPa) ukuqinisekisa ukubunjwa kwe-nugget ehambelanayo kunye nokunciphisa i-spatter.
Ukhetho Lwenkqubo:Sebenzisa i-"hard" (iphezulu yangoku, ixesha elifutshane) okanye "i-soft" (ixesha eliphantsi, ixesha elide) ishedyuli ye-welding ukulawula umthwalo we-thermal kwi-electrodes.
Izinto ezingafanelekanga ze-Electrode
Ukukhetha izinto ezingalunganga ze-electrode kwisicelo yimbangela ehamba phambili yokunxiba kwangaphambi kwexesha.
I-Chromium Zirconium Copper (CrZr):Ukhetho lwenjongo ngokubanzi{{0} olune-conductivity elungileyo kunye nokuqina kwekhabhoni kunye neentsimbi ezingenastainless, kodwa zinxiba ngokukhawuleza -amandla aphezulu okanye imathiriyeli eqhubayo.
I-Aluminiyam i-Oxide Copper (i-Alumina Cu):Ukumelana nokugqwesa okugqwesileyo (i-5x ngaphezulu kwe-CrZr), ilungele intsimbi ye-galvanized kunye ne-aluminium, ekulungele ukunamathela.
Ubhedu lweTungsten (WCu) / iMolybdenum:Ubushushu obuphezulu-bubulukhuni bubenza bafaneleke kwizinto ezisebenza kakhulu ezifana nobhedu kunye nobhedu, nangona zibiza kakhulu.
Izisombululo:
Tshatisa iMathiriyeli neSicelo:Sebenzisa i-Alumina Cu yentsimbi; khetha iWCu yealloyi zobhedu.
Uyilo oludityanisiweyo:Ukusetyenziswa okufunwayo, sebenzisa i-electrodes yokufaka (umzekelo, i-tungsten tip efakwe kumzimba we-CrZr) ukudibanisa i-conductivity kunye nokumelana nokugqoka.
Ukupholisa okusebenzayo kubalulekile. Inkqubo engaphumeleliyo yimbangela efihliweyo yokugqoka i-electrode engaqhelekanga.
UkuMpompoza Amanzi/Ubushushu obumbi:Ukuhamba okungonelanga okanye ubushushu obuphezulu bamanzi buthintela ubushushu ukuba bungathwali, nto leyo ebangela ukuba i-electrode ifudumale kwaye ithambe.
Imigca Evaliweyo:Isikali okanye ubutyobo kwiitshaneli zokupholisa zenza iindawo ezishushu, ezikhokelela kwi-deformation yendawo.
Izisombululo:
ULondolozo lwarhoqo:Sebenzisa uluhlu lokukhangela lwenkqubo yokupholisa. Beka esweni izinga lokuhamba kunye nobushushu. Sebenzisa amanzi adiyiniweyo okanye isisipholisi esikhethekileyo ukuthintela ukwakheka kwesikali.
Lungiselela uyilo:Qinisekisa ukuba imijelo yokupholisa yangaphakathi icacile. Khetha ii-electrode ezinamabhobho amakhulu kunye nee-overhangs ezimfutshane ukwandisa ukuchithwa kobushushu.
IMeko yoMphezulu woMsebenzi oMbi
Ubume bomphezulu be-workpiece buchaphazela ngokuthe ngqo apho ubushushu buveliswa khona.
Izingcolisi:I-oyile, ubumdaka, kunye ne-oxide layers zonyusa ukuxhathisa komphezulu, kubangela ukuba ubushushu bugxile kwi-electrode -i-workpiece interface, ekhokelela kubushushu obugqithisileyo kunye nongcoliseko.
Ukuncamathela kweSlash:I-spatter yentsimbi enyibilikisiweyo inokunamathela ebusweni be-electrode, iguqule imilo yayo kunye nokukhawuleza ukunxiba kwi-welds elandelayo.
Izisombululo:
Ngaphambi-ukucoca:Misela{0}}inkqubo yokucoca i-weld yangaphambili usebenzisa i-degreasers okanye izicoci ze-ultrasonic ukususa ungcoliseko. Unyango lwangaphambili (umzekelo, ukukha) lubalulekile kwimathiriyeli efana nentsimbi.
Ugcino lwePost{0}weld:Ucoce rhoqo iingcebiso ze-electrode kunye nefayile ezinikeleyo okanye isinxibo sokususa i-buildup kunye nokugcina ucoceko, umphezulu wokunxibelelana osicaba.
Ukuqukumbela
Ukunxiba kwe-Electrode kumgama-ophakathiumatshini wokuwelda indawongumba -omacala amaninzi, kodwa unokulawulwa ngokusebenzayo. Ngokulungiselela iiparamitha zenkqubo, ukukhetha izinto ezichanekileyo ze-electrode, ukugcina inkqubo yokupholisa, kunye nokuqinisekisa iindawo zokusebenza ezicocekileyo, unokwandisa kakhulu ubomi be-electrode, uphucule ukuhambelana kwe-weld, kunye nokunciphisa iindleko zizonke.
