Otereeza otya ekyuma kya medium frequency spot welding okusobola okutuuka ku effect esinga okutuukirawo?

Fine-Okulongoosa YoMFDC Omuweesi w’ebifo: Ekitabo ky'okuteekawo amangu

Okufuna welds ezitakyukakyuka neabaweesi b’amabala aba medium-frequency direct current (MFDC).kyetaagisa okutebenkeza ensengeka ssatu ezikulu:kati, obudde, ne puleesa. Laba engeri gy'oyinza okubakubamu essimu mu:

1. Ennongoosereza mu kiseera kino: Fuga Ebbugumu

Tandika wansi: Ku kyuma ekigonvu ekya mm 0.8, tandika ku 200-300A.

Test & increase: Situla current mu mitendera gya 10% okutuusa lw'olaba:
✅ Okuyingira kwa nugget mu bujjuvu (tewali biyungo binafu) .
❌ Tewali kufuuwa oba kwokya-okuyita (kiraga akasannyalazo akasukkiridde) .
Tip ya aluminiyamu: Kozesa current eya wansi ebitundu 30-50% okusinga ekyuma olw’obutambuzi obusingako.

2. Obudde bw’okuweta: Dukanya Ebbanga ly’ebbugumu

Ekyuma: Ekiseera ekitono + akasannyalazo akangi (okugeza, 3-6 sec @ 320A ku M6 nuts)

Aluminiyamu/Ekikomo: Ekiseera ekiwanvu + akasannyalazo akatono
Okulabula:=electrode empanvu ennyo okunywerera; Okuyungibwa okumpi ennyo=okutajjuvu.

3. Puleesa ya Busannyalazo: Kakasa nti Tukwatagana

Ebipande ebigonvu (<1mm): 0.3-0.5 MPa

Thick plates (>3mm): 0.8-1.2 MPa
Critical ratio: Yongera pressure 5% ku buli 10% current boost.
Galvanized steel fix: Kozesa Puleesa esinga oba eyenkana 0.6MPa okuziyiza okufuukuuka kwa zinki.

4. Okuddaabiriza Obusannyalazo: Okukwatagana kye kisumuluzo

Sharpen tips: Siiga buli weld 50-100 ne sandpaper ennungi.

Onnyogoze bulungi: Kebera okutambula kw’amazzi buli wiiki – obusannyalazo obugonvu buleeta okuwuguka.

Anti-stick: Siiga ekikuta kya graphite ng’oweta aluminiyamu.

Pro Amagezi ku Setup

• Gezesa kinnoomu: Teekateeka parameter emu omulundi gumu.
• Kakasa obutakyukakyuka: Pima obuwanvu bwa nugget – enjawulo<0.2mm.
• Teeka ebifaananyi (profiles).: Teeka ensengeka ezisinga obulungi ez’ebintu eby’enjawulo.

Ekivaamu ekituufu: Ekkolero lyayongera ku bulamu bwa electrode okuva ku ssaawa 500 okutuuka ku 1200 nga liyita mu kusiba ensonga bulijjo n’okulongoosa okunyogoza.
