Nhyɛso nyɛ nhyehyɛe kɛkɛ-ɛyɛ...fapema ɛyɛ papa wɔ medium mufrequency spot welding a wɔde yɛ adwuma. Bere a MF welders a wɔakɔ anim de pɛpɛɛpɛyɛ ma no, ahoɔden a ɛmfata de sintɔ ahorow a ɛtaa ba no 70% ba sɛnea HAIFEI afuw mu nsɛm kyerɛ no. Saa nhyɛso-adwumayɛ nkitahodi yi ntease tetew welding a ɛfata fi nea efi mu ba soronko ho.
Nea Enti a Nhyɛso Kyerɛ Weld Integrity
Electrode ahoɔden na ɛma anyinam ahoɔden kwan no ba. Nhyɛso a ɛnnɔɔso ma nkitahodi a ɛko tia no yɛ kɛse, na ɛde ɔhyew a ɛboro so wɔ mpɔtam hɔ, dade a wɔpam ("splash"), ne nuggets a ɛyɛ mmerɛw ba. Ahoɔden a ɛboro so ma nneɛma a wɔde yɛ adwuma no yɛ petee, ɛtew mprempren density so, na ɛma weld a ɛyɛ nwini ba. HAIFEI nhwehwɛmu si nhyɛso a eye sen biara so dua:
- Ɛtew contact resistance so 40-60% .
- Ɛhwɛ hu sɛ 95%+ nugget a ɛyɛ pɛpɛɛpɛ
- Ɛtrɛw electrode nkwa nna mu 3x
HAIFEI Nhyɛso a Wɔde Di Dwuma Ho Nhyehyɛe no
Calibrate nyansa kwan so:
- Mfitiaseɛ: Fa ahoɔden si 0.8-1.2 kN/mm2 wɔ electrode anim beaeɛ (sɛ nhwɛsoɔ no, 5mm ano ≈ 150-250 kgf).
- Nneɛma a Wɔde Yɛ Nsakrae: +20% ma dade a ɛnyɛ den, -15% ma aluminium a wɔde afra.
- Fa dijitaal manometers di dwuma ma live monitoring.
Fa Parameters no yɛ pɛ:
| Nsɛm a ɛfa ho | Nhyɛso mu Nsakrae | Adeyɛ a Wɔde Tua Ka |
|---|---|---|
| Nneɛma a Wɔde Yɛ Adwuma ↑ | +15-25% | Nkɔanim weld bere 10-20% . |
| Wɔahu sɛ Wɔpam Wɔn | +10% Ntɛm ara | Tew mprempren 5% so . |
| Electrode a Ɛbata Ho | +8% & polish afotuo | Tew bere a wɔde kura mu 30-50% . |
Automate & Validate: Ɔde ne nsa kyerɛɛ ne so.
- Fa servo-mframa nhyehyɛe ne ahoɔden-displacement curves bom. Post-weld, abrabɔ:
- Peel sɔhwɛ ahorow (ma thin gauge) .
- Cross-sectioning (ma nugget a ɛkɔ mu no yɛ nokware) .
- Chisel sɔhwɛ ahorow (hwɛ sɛnea ɛka bom) .
Nea Efi Mu Ba a Wɔada no Adi
- HAIFEI afɛfoɔ a wɔde saa protocol yi redi dwuma no amanneɛbɔ:
- 90% a ɛso tew wɔ weld rework mu
- 22% ntɛmntɛm kyinhyia mmere denam arcing a ɛyɛ den so
- Electrode a wɔde di dwuma no so tew 35% .
