I-Spatter yenye yezona ngxaki zixhaphakileyo kwaye zinexabiso elikhulu kwi-resistance spot welding. Izibalo zemizi-mveliso zibonisa ukuba ngaphezulu kwe-30% yeziphene ze-spot welding zinxulumene ngokuthe ngqo nokutshiza okugqithisileyo. Ayichaphazeli nje ukubonakala kwe-weld, kodwa inciphisa amandla adibeneyo, ikhawuleza ukunxiba kwe-electrode, inyuse iindleko zokucoca, kwaye idale iingozi ezinokubakho zokhuseleko.
Medium frequency spot welding machine welding umboniso
Xa kuthelekiswa neziweldi zeendawo ze-AC, i-MFDC (i-Medium Frequency DC)oomatshini bokuwelda amabalazibonelela ngokuchaneka kolawulo oluphezulu, impendulo ekhawulezayo, kunye nolawulo olungcono lwamandla, okwenza kube sisisombululo esisebenzayo soxinzelelo lwe-spatter. Eli nqaku libonelela ngohlalutyo lobuchule olubanzi lwendlela abashiseli be-MFDC abasusa ngayo ngokucwangcisiweyo be-welding spatter kwimveliso yanamhlanje.
1. I-Workpiece Surface Ukucoceka: Umgca wokuQala woKhuselo ngokuchasene ne-Spatter
Uvavanyo olubanzi lwe-welding luqinisekisa ukuba:
- Amathuba e-Spatter akhula ngamaxesha angama-2-4 xa ioli, irusi, okanye i-oxidation ikhona kumphezulu wezinto eziphathekayo.
Izinto ezingcolisayo zibangela ukunganyangeki koqhagamshelwano, okukhokelela ku:
- Ngesiquphe ubushushu spikes
- Ugqabhuko lwentsimbi lwasekuhlaleni
- Ukukhutshwa kwentsimbi etyhidiweyo enobundlobongela
Imigangatho yoShishino eCetyisiweyo:
- Ukuchasa ukudibana komphezulu:50–200 μΩ
- Ubukhulu befilimu ye-oyile:Ngaphantsi okanye ilingana ne-10 μm
- Umaleko oksijini: Ususwe ngokupheleleyo ngokusila, ngokuxukuxa, okanye ngokucoca ngemichiza
Ngokucocwa komphezulu ofanelekileyo (ukucoca utywala, ukucocwa kwe-ultrasonic, okanye imigca yokususa igrisi ngokuzenzekelayo), amazinga e-spatter anokwehliswa ngama-40-60% ngaphambi kokuba i-welding iqale.
2. Ulawulo lweParameter ye-Welding echanekileyo: Ingundoqo ye-Spatter Suppression
Iiparamitha ezintathu ezisisiseko ze-welding zezi:
- I-Welding yangoku (kA)
- Ixesha le-Weld (ms)
- Uxinzelelo lwe-Electrode (kN)
Ezi parameters kufuneka zihlale kwibhalansi eguqukayo. Nakuphi na ukutenxa kunokubangela i-spatter ngokukhawuleza.
Uluhlu lweeParamitha eziKhuselekileyo ngokweMathiriyeli:
| Uhlobo lwezinto eziphathekayo | Uluhlu lwangoku | Ixesha le-Weld | I-Electrode Force |
| Intsimbi ebandayo- | 6–12 kA | 100–300 ms | 1.5–3.5 kN |
| Intsimbi eGalvanized | 7–14 kA | 120–350 ms | 2.0–4.0 kN |
| Yenziwe ngentsimbi eshayinayo | 8–16 kA | 80–250 ms | 2.5–5.0 kN |
| Iialloyi zobhedu | 12–25 kA | 50–180 ms | 3.0–6.0 kN |
Ezimbini-Inqanaba lolawulo lwangoku lweNtsimbi eGazisiweyo
Izinto ezenziwe ngegalvanized zithandwa kakhulu ukutshiza ngenxa ye-zinc vaporization. Ishishini-isisombululo esisemgangathweni sinezigaba ezibini-zolawulo lwangoku:
- Inqanaba 1:Okwangoku okuphantsi ukugqobhoza i-zinc coating
- Inqanaba lesi-2:I-welding eqhelekileyo yangoku ukwenza i-weld nugget ezinzileyo
Idatha yasendle ibonisa ukuba izigaba ezimbini - zolawulo lwangoku zinciphisa isitshizi kwintsimbi yegalvanized ngaphezu kwama-50%.
I-MFDC spot welders yenza i-0.1 ms{1}}izinga lokuchaneka kwedijithali ngoku, nto leyo eyenza le nkqubo izinze kakhulu kwaye iphindeke.
3. Ulawulo lweNkqubo ye-Electrode: Isizathu esikhulu esifihlakeleyo se-Spatter
Ngaphezulu25% yokutshiza{0}ukusilela okunxulumene nokusuka ekunxityweni kwe-electrode okanye ungcoliseko, kuquka:
