Ni an y’a suma ni laadala AC spot welders ye, MFDC (Medium Frequency DC) .spot welda masinwdi kɔlɔsili kɛcogo ɲumanba di, jaabi teliya la, ani fanga labɛnni ɲuman, o b’a to u bɛ kɛ fura ɲumanba ye sɔgɔsɔgɔninjɛ kunbɛnni na. Nin barokun in bɛ fɛɛrɛko sɛgɛsɛgɛli bɛɛ kɛ, min b’a jira cogo min na MFDC spot welders bɛ welding spatter ban cogo labɛnnen na bi fɛn dilanni na.
1. Baarakɛminɛnw sanfɛla saniya: Lakanali sira fɔlɔ min bɛ kɛ ka ɲɛsin sɔgɔsɔgɔninjɛ ma
Welding sɛgɛsɛgɛlibaw y’a jira ko:
- Sɔgɔsɔgɔninjɛ sɔrɔli bɛ bonya ni siɲɛ 2–4 ye ni tulu, nɔgɔ walima oksidan bɛ fɛn in sanfɛ.
Nɔgɔw bɛ kɛ sababu ye ka ɲɔgɔn sɔrɔbaliya sabati, o bɛ na ni:

2. Soudure Paramètre Contrôle précis: The Core of Spatter Suppression
Welding paramètres jɔnjɔn saba ye:
- Soudure Current (kA) .
- Soudure Waati (ms) .
- Elektɔri tansiyɔn (kN) .
O paramɛtɛrɛw ka kan ka to balansi dinamiki kɔnɔ. Ni fɛn o fɛn bɛ bɔ ɲɔgɔn na, o bɛ se ka kɛ sababu ye ka sɔgɔsɔgɔninjɛ bila sen kan o yɔrɔnin bɛɛ.
Paramɛtiri lakananenw cogoyaw ka kɛɲɛ ni fɛnw ye:
| Fɛnɲɛnɛma suguya | Sisan Range (Range) min bɛ yen | Weld Waati | Elektɔri fanga |
| Nɛnɛ-Nɛgɛ wulilen | 6–12 kA ye | 100–300 ms | 1,5–3,5 kN ye |
| Nɛgɛ Galvanisé (Galvanisé) ye | 7–14 kA ye | 120–350 ms | 2,0–4,0 kN ye |
| Inox ye | 8–16 kA ye | 80–250 ms | 2,5–5,0 kN ye |
| Kupu Alloys (Kupu Alliés). | 12–25 kA ye | 50–180 ms | 3,0–6,0 kN ye |
Filanan-Stage Current Control ka ɲɛsin Galvanized Steel ma
Fɛn minnu bɛ kɛ ni galvanize ye, olu ka teli ka sɔgɔsɔgɔ kɛrɛnkɛrɛnnenya la ka da zinki labɔli kan. Industri-standard solution ye fila-taamasenɲɛ sisan kɔlɔsili ye:
- Etape 1: 1 .Kuran dɔgɔman ka kari ka tɛmɛ zinki dacogo kan

Foro kunnafoniw b’a jira ko kuran kɔlɔsili dakun fila- bɛ dɔ bɔ sɔgɔsɔgɔninjɛ la nɛgɛ galvanisé kan ni 50% ni kɔ ye.
MFDC spot welders bɛ se ka 0,1 ms-level digital current precision kɛ, o b’a to nin wale in bɛ sabati kosɛbɛ ani ka segin a kan.
3. Elektɔriw ka sigida ɲɛnabɔli: Sɔgɔsɔgɔninjɛ sababu dogolenba dɔ
A kan25% of spatter-related failures bɛ bɔ elekitorode sɛgɛn walima nɔgɔli la, i n’a fɔ:
- Tip erosion jugumanba
