3. Adwumayɛ Ahobammɔ Mmara
- Mmienu-Nsa Dwumadi Nnyinasosɛm:
Fi ase button ntam kwan a ɛsõ sen anaasɛ ɛyɛ pɛ 300mm (siw nsa biako-a ɛkanyan wɔ akwanhyia mu ano).
Ɛsɛ sɛ nsa kɔ so mia kosi sɛ wobewie welding (sɛ wɔatwa mu a, gyae discharge).
- Ɔkwan a Wɔfa so Di Dwuma a Ɛnyɛ Ne kwan so:
Mia red emergency stop button ntɛm ara sɛ ɛba sɛ discharge abnormality (twa main circuit<0.1 seconds).
Fa exhaust system no yɛ adwuma wɔ sikɔne 30 mu bere a wusiw alarm akanyan akyi (mframa ahoɔhare Kɛse sen anaasɛ ɛne 8m/s yɛ pɛ).
III. Adwumayɛ Tebea Titiriw Dwumadi Gyinapɛn
1. Multi-Layer Nneɛma a Ɛnsɛ Welding
- Nsɛntitiriw a Ɛfa Dwumadi Ho:
Adopt anammɔn discharge mode: kan low voltage sɛ wobɛbubu oxide layer (200-300V / 3ms).
Set nhyɛso gradient nhyehyɛe: pre-nhyɛso (50N) → welding nhyɛso (300N) → kura nhyɛso (150N).
Asɛm: Battery adwumakuw bi maa nugget diameter consistency tu mpɔn 40% denam abiɛsa-stage nhyɛso control bere a welding 0.2mm aluminium + 0.15mm nickel.
2. Nneɛma a Wɔde Di Dwuma a Ɛma Nhumu a Ɛkorɔn
- Nsakrae a Wɔyɛ wɔ Adeyɛ mu:
Fa surface-roughened electrodes (Ra0.8→Ra3.2, contact resistance so tew 60%) di dwuma.
Ma ahoɔden a wɔde gu mu no nkɔ soro 10%-15% de tua reflection loss no ka.
- Ahobammɔ Ho Kɔkɔbɔ: Ɛsɛ sɛ wohyɛ anti-glare anim kyɛm (sunsuma nɔma Kɛse sen anaasɛ ɛne 12 yɛ pɛ).
