Lafiya -Yana Gyaran kuMFDC Spot Welder: Jagorar Saita Sauri
Samun m welds tare damatsakaici - mitar kai tsaye (MFDC) tabo waldayana buƙatar daidaita saitunan maɓalli uku:halin yanzu, lokaci, da matsi. Ga yadda ake buga su:
1. Daidaita Yanzu: Sarrafa Zafin
Fara low: Don 0.8mm m karfe, fara a 200-300A.
Gwaji & haɓaka: Tada halin yanzu cikin matakai 10% har sai kun ga:
✅ Cikakkun shigar nugget (babu raunin haɗin gwiwa)
❌ Babu spatter ko ƙone{0} ta (yana nuna wuce gona da iri)
Aluminum tip: Yi amfani da 30-50% ƙananan halin yanzu fiye da karfe saboda haɓakar haɓaka.
2. Lokacin walda: Sarrafa Tsawon Zafi
Karfe: ɗan gajeren lokaci + babban halin yanzu (misali, 3-6 sec @ 320A don M6 kwayoyi)
Aluminum/Copper: Tsawon lokaci + ƙananan halin yanzu
Gargaɗi: Tsawon tsayin daka=lantarki; Gajeren=rashin cikar hadewa.
3. Matsi na Electrode: Tabbatar da lamba
Karan zanen gado (<1mm): 0.3-0.5 MPa
Thick plates (>3mm): 0.8-1.2 MPa
Mahimmancin rabo: Ƙara matsa lamba 5% don kowane haɓaka 10% na yanzu.
Galvanized karfe gyara: Yi amfani da Mafi Girma ko daidai da matsa lamba 0.6MPa don hana zuriyar zinc.
4. Kulawar Electrode: Daidaituwa shine Maɓalli
Ƙaƙwalwar tukwici: Niƙa kowane welds 50-100 da takarda mai kyau.
Yi sanyi da kyau: Duba kwararar ruwa mako-mako - na'urori masu laushi suna haifar da ɗigon ruwa.
Anti{0}}sanda: Aiwatar da manna graphite lokacin walda aluminum.
Pro Tips don Saita
- Gwada akayi daban-daban: Daidaita siga guda ɗaya a lokaci guda.
- Tabbatar da daidaito: Auna diamita nugget - bambancin<0.2mm.
- Ajiye bayanan martaba: Ajiye mafi kyawun saitunan don kayan daban-daban.
Sakamako na gaske: Wani masana'anta ya tsawaita rayuwar lantarki daga sa'o'i 500 zuwa 1200 ta hanyar tufafi na yau da kullun da inganta yanayin sanyaya.
Gyaran Magana Mai Sauri
| Batu | Yiwuwar Gyara |
|---|---|
| Spatter | ↓ Yanzu ko ↑ Matsi |
| Weld mai rauni | ↑ Yanzu + ↑ Lokaci |
| Electrode Stick | ↓ Lokaci + Tsaftace Tukwici |
