Kwimveliso yomzimba weemoto, iindibano ze-elektroniki, kunye neenkqubo ezahlukeneyo zokwenza isinyithi,ukuwelda indawoihlala iyeyona ndlela ikhawulezayo nenamandla{0}esebenzayo yokujoyina. Ukomelela kunye nokuthembeka kweweld nganye kuxhomekeke kakhulu kumgangatho we-weld nugget{2}}indawo yentsimbi edityanisiweyo eyenziwe phakathi kwezinto ezimbini zokusebenza.
Ukuba i-nugget incinci kakhulu, ayihambelani, okanye yenziwe kakubi, i-weld joint inokusilela phantsi komthwalo. Ukufikelela ngokuthe gqolo ukufezekisa ii-welds ezinamandla neziphindaphindwayo, kubalulekile ukuqonda izinto eziphambili eziphembelela ukwenziwa kwe-nugget.
Esi sikhokelo sicalula ezona zinto zintlanu zibaluleke kakhulu ezichaphazela umgangatho we-spot weld nugget, zixhaswa ngokusebenzisekayo,{0}}ukusebenzisa{1}}idatha elula.
1. Ulawulo lwangoku oluchanekileyo noluZinzileyo
Ukuveliswa kobushushu kwi-welding yendawo ibotshelelwa ngokuthe ngqo kumbane wombane. Nokuba ukuguquguquka okuncinci kunokutshintsha kakhulu ubungakanani be-nugget.
Kutheni kubalulekile nje?
- Uphantsi ngoku:ubushushu obungonelanga → i-nugget encinci okanye engagqibekanga
- Ngoku ngokugqithisileyo:ukutshisa kakhulu → ukutshisa-ngokuphuma, ukugxothwa, okanye ukuba buthathaka ilungu
Uluhlu lweparameter eqhelekileyo
| Izinto eziphathekayo | Weld yangoku | Ixesha le-Weld |
|---|---|---|
| Intsimbi ephakathi | 10–14 kA | 10–30 imijikelo |
| Intsimbi yegalvanized | Kancinci ngaphantsi kwentsimbi epholileyo | 8–20 imijikelo |
| Aluminiyam ialloys | 60–80 kA | 8–15 imijikelo |
Qaphela: I-MFDC welders (1-5 kHz) inikezela ngolawulo oluchanekileyo lwangoku kunye nokunciphisa ukulahleka kobushushu xa kuthelekiswa neenkqubo ze-AC.
Iinkqubo ezigqwesileyo

2. I-Electrode Force efanelekileyo
Amandla e-Electrode achaphazela ukuxhathisa koqhagamshelwano kunye nendlela isinyithi esinyibilikisiweyo esenza ngayo i-nugget.
Imingcipheko yamandla angachanekanga
- Amandla amancinane kakhulu:uqhagamshelwano olungazinzanga, ukuchasana ngokugqithisileyo, ii-nuggets ezingahambelaniyo
- Amandla amaninzi kakhulu:isinyithi esinyibilikisiweyo sikhanywa ngaphandle, sinciphisa i-nugget diameter
Uluhlu lwamandla olucetyiswayo
Ngentsimbi ye-carbon 1.0-2.0 mm:
- 7,000–9,000 N
-
Ubungakanani benugget ekujoliswe kuyo
- I-nugget diameter ≈ 1.2-1.5 × ubukhulu beshiti
Lo mlinganiselo uqhele ukubhekiselwa kuwo kwiimoto wimigangatho endala.
