Ol Laitpela Bodi Advansmen: Haifei's Joining Solusen
Haifei Welding SystemsAdvans Automotive Lightweighting:
- Projeksen Welding bilong PHS Skru/Nut
- Aplikesen: Ol tanel asembli long fran plua
- Robotic Resistance Spot WeldingOl wokstesen bilong ol 'Aluminium Crash Beams'
Long wanem, ol i laik bai ol i no gat planti kabon, olsem na 'lightweighting' bilong ol kar i kamap bikpela samting long skruim 'range' bilong EV. Tripela bikpela rot i helpim long daunim hevi bilong bodi:
① Ol nupela samting(laitweit aloi & komposit)
② Struktural Optimaisesen
③ Advans Manufakturing
Materiel-Spesifik Joining Teknoloji
| Sistem bilong ol samting | Ol bikpela rot bilong joinim | Ol bikpela wok |
|---|---|---|
| Steel Dominant | Welding (95%) | Resistance Spot Welding (RSW), GMAW |
| Bodi bilong aluminium | Pasin bilong pasim long masin | SPR, FDS, Adhesive Bonding |
| Steel-Aluminum Hybrid | Hybrid Joining | RSW + MIG + SPR/FDS |
| Multi-Material | Integreted Koneksen | RSW, Adhesives, SPR/FDS, Laser Welding |
SPR: Self-Piercing Riveting|FDS: Flow Drill Screwing
Ol Laitweit Enabler bilong Haifei
1. Presim-Hardened Steel (PHS) Solusen
Nat/bolt projeksen welding bilong:
✓ Ol rot bilong fran plua
✓ Crash beams (shear strength >12kN)
2. Aluminium Joining Systems
Ol wokstesen bilong robot RSW wantaim:
✓ 200Hz medium-frikwensi inveta
✓ Kontrol bilong strong bilong elektrod (±1.5%)
3. Multi-Material Adaptas
- Ol CD welda bilong kabon faiba/ain stak
- AI-kontrolim SPR sistem
Teknikel Impak
EV Range Boost: 7% hevi i go daun → 5% mak i go antap (SAE stadi)
Joint Efficiency: Aluminium RSW i winim 90% strong bilong bes metal vs. 70% wantaim ol glu
*Kes: 4-stesen PHS nat welding lain bilong Haifei i mekim 'throughput' i go antap long 40% long wanpela Tier-1 saplaia.*
Ol samting bilong bodi bilong kar na joinim evolusen:
Long wanem ol i laikim ol samting bilong bodi i no hevi tumas, ol samting bilong bodi i kamap kain kain long ol samting bilong bipoolgeta - ain straksalongmulti-material sistem, we i nidim ol gutpela teknoloji bilong joinim:
- Welding
- Pasin bilong pasim long masin
- Adhesive Bonding
