- Asiane a ɛwɔ hɔ sɛ arc bɛhyew sɛ nneɛma a ɛwɔ soro no ho ntew a.
- Nnwuma a Wɔde Di Dwuma: Eyi ne mfiridwuma titiriw a ɛwɔ HAIFEI mfiri ahorow no akyi, a wɔde di dwuma kɛse de yɛ nneɛma piikɔbere nkitahodi ahorow a ɛyɛ mmerɛw (busbars), batere nkitahodi ahorow, ne shims a wɔde laminated ayɛ.
Ɔhyew Isostatic Pressing (HIP) Ntrɛwmu Welder
- Nnyinasosɛm:Wɔde afã horow no gu anwenne a nhyɛso kɛse wom mu. Wɔde mframa a ɛnyɛ adwuma (Argon) ahyɛ dan no mu ma, a wɔma ɛyɛ hyew na wɔde nhyɛso hyɛ mu bere koro mu, na wɔde di dwumaisostatic a ɛyɛ isostatic(ɛyɛ pɛ fi afã horow nyinaa) nhyɛso.
- Nneɛma Titiriw a Ɛwɔ Hɔ:
Wim tebea:High-nhyɛso inert gas (ɛkɔ 200 MPa).
Ɔhyew a wɔde yɛ adwuma:Fononoo a ɛwɔ nhyɛso anwenne no mu.
Nhyɛsoɔ:Isostatic, eye ma nsusuwii ahorow a ɛyɛ den.
- Mfaso a ɛwɔ so:
Yi emu porosity fi hɔ na ɛma 100% dense bonds.
Ɛyɛ pɛpɛɛpɛ ma bonding complex, irregular shapes.
- Mfomso ahorow:
Nnwinnade ne adwumayɛ ho ka a ɛkɔ soro yiye.
Adeyɛ no kyinhyia a ɛyɛ brɛoo yiye.
- Nnwuma a Wɔde Di Dwuma:Powder dade a wɔhyɛ mu den, bonding complex castings, turbine blades a wosiesie, ahunmu afã horow a ɛho hia.
Nkyekyɛmu denam Pressure Application Ɔkwan so
a) Uniaxial (Plate a ɛyɛ tratraa) Nsɛmma nhoma
- Nkyerɛmu:Eyi ne ɔkwan a wɔtaa de di dwuma. Wɔde hydraulic cylinders anaa servo motors na ɛde nhyɛso ba axis biako so (wɔ vertically).
- Sɛnea ɛfata:Ɛyɛ papa ma nneɛma a ɛyɛ tratraa anaa ɛnyɛ den a ɛyɛ kurukuruwa te sɛ ntama, mprɛte, ne busbars.
- Anohyeto ahorow:Ebia nhyɛso kyekyɛ nyɛ pɛ wɔ 3D geometries a ɛyɛ den yiye so.
b) Isostatic (HIP) Nsɛmma Nhoma Tintimbea
- Nkyerɛmu:Sɛnea yɛaka ho asɛm wɔ atifi hɔ no, wɔde mframa a wɔde yɛ ade na ɛde nhyɛso fi mmeae nyinaa ba pɛpɛɛpɛ.
- Sɛnea ɛfata:Ɛho hia ma nneɛma a ɛyɛ den, net-shape components.
c) Nsonsonoeɛ Gas Nhyɛsoɔ
- Nkyerɛmu:Nsakraeɛ a ɛwɔ baabi a vacuum fã bi wɔ ɔfa baako ne high-pressure gas wɔ ɔfã foforɔ no ma nhyɛsoɔ nsonsonoeɛ ba de bom afã ahodoɔ no.
