EV Battery Busbar ni a matu Diffusion Welding ngu ai gaw hpa rai ta?
Diffusion welding a madung tara
Diffusion welding galaw ai gawngang kang ai-mungdan n-gun ja ai ladat. Metal ni hpe n-gun dat na malai, 1000 hpe bang nna, arai ni hpe matut mahkai ya ai.katsi ai, n-gun, hte atendai majaw atom ni gaw n-gup magap hku nna bra ayai nna, metallurgical bond byin wa ai.
Dai lam galaw ai aten hta:
- Dai arai ni hpe hkang lu ai n-gun npu hta shinggrup da ai.
- Welding galaw ai shara hpe masat da ai nbung katsi ai shara de (melting point a lawu de law malawng) katsi shangun ai.
- Atomic diffusion gaw matut mahkai ai lam hta byin pru wa ai.
- Melting (sh) filler arung arai ni n lawm ai sha ngang kang ai joint langai byin pru wa ai.
Ndai ladat gaw grau nna 2019 ning a matu htap htuk ai.magri busbar ni, aluminium busbar ni, hte n-gun rawng ai matut mahkai lam ni, dai shara hta wan n-gun n-gun hte npawt nhpang n-gun atsam gaw ahkyak ai.
Hpa majaw EV Battery Busbar ni hpe garan kachyan ai lam galaw ra ai
Battery busbar ni hta ra ai lam ni gaw:
