Yenziwe ngentsimbi eshayinayoyimathiriyeli esetyenziswa ngokubanzi eyaziwa ngokugqwesa kwayo ukumelana nomhlwa kunye neempawu zoomatshini. I-Medium frequency inverter spot welding ibonelela ngeenzuzo ezizodwa ngokuchaneka, ulawulo, ukuwelda indawo yinkqubo enye yokuwelda.ukumelana welding, kunye nomgangatho we-welding yensimbi engenasici. Kweli nqaku, siza kuphonononga inkqubo kunye neengqwalaselo zokumelana nebala lokuwelda intsimbi engenasici.
Ukukhethwa kwezinto kunye noLungiselelo:Ukukhetha insimbi engenasici efanelekileyo esekelwe kwiimfuno ezithile zesicelo kubalulekile ngaphambi kokuqala inkqubo ye-welding. Insimbi engenasici iqulethe izinto ezahlukeneyo ze-alloy ezifana nechromium, nickel, kunye ne-molybdenum, ezinegalelo ekuxhathiseni ukubola kunye nokuwelda. Ukongeza, umphezulu we-workpiece kufuneka ucocwe ngokufanelekileyo kwaye ungabi nazingcolisi ukuqinisekisa ukuba umgangatho we-welding uphezulu.
Ukhetho lwe-Electrode:Ukhetho lwe-electrode lubalulekile xa u-welding steel stainless steel. Kunconywa ukusebenzisa i-electrodes eyenziwe kwizinto ezihambelana nensimbi engenasici, ezifana ne-chromium zirconium yobhedu okanye i-alloys zethusi. Ezi electrode zinika ukuhanjiswa kombane okulungileyo kunye nokuzinza kwe-thermal, ukuqinisekisa ukuhanjiswa kwamandla okusebenzayo kunye nobomi obude be-electrode.
Imilinganiselo yeWelding:Ukuweld ngempumelelo intsimbi engenasici, kubalulekile ukulawula ngokuchanekileyo iiparamitha zokuwelda. Izinto ezifana ne-welding yangoku, ixesha, kunye noxinzelelo kufuneka ziphuculwe ngokusekwe kwinqanaba kunye nobukhulu bentsimbi engenasici. Ngokuqhelekileyo, i-welding current ephantsi ikhethwa ukunciphisa igalelo lokushisa kunye nokukhusela i-deformation ngelixa uqinisekisa ukudibanisa okufanelekileyo kwezinto. Ubukhulu obahlukeneyo beepleyiti zensimbi ezingenasici buya kufuna imisinga ye-welding eyahlukeneyo kunye namaxesha. Ngoko ke, kufuneka ukwazi iiparitha ezifanelekileyo ze-welding kwi-thickness nganye yensimbi engenasici. Apha ngezantsi kukho itafile yeeparameters zokuwelda kwindawo yokuwelda intsimbi engatyiwayo.
| Tukuphakama/mm | I-Electrode incam ububanzi/mm | Ukuwelda yangoku/A | Ixesha/amaxesha okuwelda | Uxinzelelo lwe-electrode/N |
| 0.3 | 3.0 | 3000~4000 | 0.04~0.06 | 800~1200 |
| 0.5 | 4.0 | 3500~4500 | 0.06 ~0.08 | 1500 ~2000 |
| 0.8 | 5.0 | 5000~6500 | 0.10 ~0.14 | 2400~3600 |
| 1.0 | 5.0 | 5800 ~ 6500 | 0.12 ~0.16 | 3600~4200 |
| 1.2 | 6.0 | 6500 ~7000 | 0.14 ~0.18 | 4000 ~4500 |
| 1.5 | 5.5~6.5 | 6500~8000 | 0.18 ~0,24 | 5000~5600 |
| 2.0 | 7.0 | 8000 ~10000 | 0.22 ~0,26 | 7500 ~8500 |
| 2.5 | 7.5 ~ 8.0 | 8000~11000 | 0.24~0,32 | 8000 ~10000 |
Irhasi yokuKhusela:I-Welding steel stainless ifuna ukusetyenziswa kwegesi yokukhusela ukukhusela indawo ye-weld kwi-oxidation kunye nokungcoliswa. Ukhetho oluqhelekileyo ngumxube we-argon kunye ne-helium, enika i-arc ezinzile kwaye ikhusela ngokufanelekileyo isinyithi esityhidiweyo. Isantya sokuhamba kwegesi yokukhusela kufuneka ilungiswe ukuze kuqinisekiswe ukukhuseleka okwaneleyo kunye nokukhuselwa ngexesha lenkqubo ye-welding.
Ubuchwephesha bokuWelding:Xa usebenzisaindawo welderkwintsimbi engenastainless, ubuchule bokuwelda bubalulekile. Kucetyiswa ukuba kusetyenziswe uthotho lwee-pulses ze-welding ezimfutshane endaweni ye-welding eqhubekayo ukunciphisa igalelo lobushushu kunye nokulawula i-weld pool. Ukongeza, ukugcina uxinzelelo olungaguqukiyo kuyo yonke inkqubo ye-welding kunceda ukufezekisa amalunga anamandla kunye afanayo.
Unyango lwasemva kweWeld:Emva kokugqiba inkqubo ye-welding, kubalulekile ukwenza unyango lwe-post-weld ukuqinisekisa ukuba insimbi engenasici ihlangabezana nemigangatho yokusebenza efunekayo. Oku kunokubandakanya iinkqubo ezifana nokupasa, ukuchola, okanye ukucoca, ngokuxhomekeke kwibakala elithile lensimbi engenasici kunye neemfuno zesicelo. Olu nyango lunceda ukubuyisela ukunganyangeki kwe-corrosion kunye nokuphelisa nayiphi na imiba enokubakho yobuzaza ebangelwa yiinkqubo welding.
Uvavanyo lwasemva kweWeld:Ukuqinisekisa ukuba amandla e-weld ayahlangabezana nemigangatho efunekayo, uvavanyo olonakalisayo okanye uvavanyo lwe-tensile ludla ngokuqhutywa emva kwe-welding. Uvavanyo olutshabalalisayo luhlola ngokubonakalayo ukuba i-weld joint ingene ngokupheleleyo kwi-workpiece. Ukuba i-joint iphuka ngokulula, i-weld ayiphumelelanga. I-weld ephumelelayo iya kukrazula isiseko sesinyithi ngaphandle kokuphula umdibaniso. Uvavanyo lwe-tensile lulinganisa awona mandla okuqina okuqinileyo ijoyinti ye-weld enokumelana nayo, ibonelela ngovavanyo lobuchwephesha ukufumanisa ukuba iyahlangabezana nemigaqo efunekayo ngokusekelwe kumandla okuqina afunekayo esixhobo sokusebenza.
I-Medium frequency inverter spot welding ibonelela ngendlela esebenzayo yokuwelda intsimbi engenasici, ibonelela ngolawulo oluchanekileyo, igalelo elincinci lobushushu, kunye nomgangatho obalaseleyo we-weld. Ngokuqwalasela izinto ezifana nokukhethwa kwezinto, ukhetho lwe-electrode, iiparamitha ze-welding, i-gas ekhuselayo, ubuchule be-welding, kunye nonyango lwe-post-weld, abavelisi banokufikelela kwi-welds ethembekileyo kunye neyomelele kwizicelo zensimbi ezingenasici. Ngeengenelo zayo zendalo, oomatshini bokuwelda bamaxesha aphakathi zizixhobo ezixabisekileyo kumashishini afana neemoto, ulwakhiwo, kunye nokulungiswa kokutya, apho ukumelana nomhlwa kunye nokuthembeka koomatshini kubalulekile.
Niniwenausei-welder yendawo ye-welding yensimbi engenasici, ulwazi olungentla kufuneka lube luncedo. Ukongeza, ukukhetha intsimbi yestainless spot welder ekumgangatho ophezulu ikwayinto ebalulekileyo.
