Copper alloys ni hpe electronics, mawdaw arung arai ni, nta kata na arung arai ni hta grai lang ai gaw, wan n-gun hpe grai kaja hkra shalai ya lu ai, n-gun n-gun hpe ninghkap lu ai, jak rung arung arai ni hta grai kaja ai majaw re. Raitim, ndai arawn alai ni gaw, n-gang (sh) aluminum hte shingdaw yang, spot welding hpe grau yak shangun ai.
-madang tsaw ai weld ni hpe lu la na matu, magri n-gang a akyang lailen hpe chye na nna, hkrak ai welding ladat ni hpe jai lang ra ai. Ndai laika buk hta, magri mang hpe gara hku kaja hkra weld galaw na hpe sang lang dan ai.spot welding jak, data-madi shadaw ai ningmu ni hte hpaga lam galaw shapraw ai lam a matu tatut hparan ladat ni hte.
Hpa majaw magri alloy ni hpe spot weld galaw na matu yak ai
Copper hte copper alloy ni gaw laklai ai welding hta yak hkak ai lam ni hpe shabyin ya ai:
1. Grai tsaw ai nbung n-gun
Copper alloy ni gaw carbon steel hta htam 7-11 grau lawan ai hku katsi ai hpe shalai ya lu ai.
→ Katsi ai gaw weld zone kaw nna kalang ta tsan mat wa ai majaw nugget byin wa na matu yak hkak wa ai.
2. Wan n-gun n law ai
Low resistance a majaw current grai loi ai hku lai wa ai majaw, joint kaw na katsi ai lam hpe shayawm ya ai.
→ Ndai lam gaw n-gun kya ai weld (sh) n hkum tsup ai fusion byin wa na masa hpe grau jat shangun ai.
3. Lawan ai hku katsi ai Rates
Lawan ai hku katsi mat ai gaw, n-gun n rawng ai, n-gun rawng ai, n bung ai nugget rawt jat wa shangun ai-grau nna magri, magri, hte high-zinc alloys ni hta.
Ndai lam ni a majaw, n-gang a matu masat da ai spot welding jak hpe hpaw da ai gaw, magri n-gang ni a matu n htap htuk ai. Hkrak ai electrode ni hte hkrak tup parameter hpe hkang lu na matu ra kadawn nga ai.
Magri hte htu sha na matu kaja ai Electrode ni hpe lata ai
1. Hpa majaw nga yang, -Conductivity Metals ni a matu galaw da ai arung arai ni hpe lata la u
Ahkaw ahkang lu ai welding lam matsun ni gaw:
| Magri htu ai amyu | Hpaji jaw ai Electrode |

| N-gun kaba ai (ga shadawn, Cu{3}}Cr, Cu-Zr) |
Hkrang 1 electrode (brai bra ai-n-gun ja ai magri) |
| Lawu na-hpyen n-gun (magri, magri) | Class 2 magri htu ai electrode ni |
Electrode hpe hkrak lata ai gaw, n-gun n-gun hpe ngang grin hkra galaw ya nna, katsi ai hpe shayawm ya lu ai.
2. Tungsten bang da ai n-gun dat ni hpe lang u
Hkrak ai magri htu ai welding galaw ai lam ni a matu:
- Tungsten bang da ai electrode ni gaw electrode kata de katsi ai hpe shayawm ya ai.
- Tungsten gaw 100 daram htum mat ai.3420 degri, magri hta grau tsaw ai.
- Hpaji jaw ai tungsten npawt nhpang galu kaba ai lam:3-4 mm.
- Nugget byin pru wa ai hpe grai shatsaw ya nna, electrode n-gun hpe shayawm ya ai.
Ndai electrode hparan ladat ni hpe mawdaw hte electronic jak ni galaw ai hta grai law hkra hkam la da ai.
Magri n-gang n-gang htu ai a matu htu ai masat masa ni hpe kaja dik htum galaw ai
Stable welds ni hpe lu la na matu, na a .spot welding jakhkrak tup ai parameter ni hte configure galaw ra ai.
1. Ya aten hte Welding aten
- Steel welding hte shingdaw yang, npu na peak current hpe lang u.
- Focused heat input hpe n-gun jaw na matu weld aten hpe kadun hkra galaw u.
- MFDC (Medium Frequency Direct Current) ladat ni gaw, n-gun n rawng ai laika man ni hpe grau kaja hkra hkang lu shangun ai (<1.5 mm).
- Fine-tuning hpe copper alloy amyu shagu hta ra ai, hpa majaw nga yang wan/hpyen n-gun atsam ni gaw grai shai hkat ai majaw re.
2. Process hpe grau kaja hkra galaw na matu hpaji jaw ga ni
- Sau, oxide, nhpu, plating n-gun ni hpe yeng seng kau na matu, ntsa hpe atsawm sha jasan jaseng u.
- N-gun rawng ai hku matut mahkai ai lam hpe ninghkap lu na matu, ra ai squeeze n-gun hpe lang u.

Manghkang hparan ai lam hta byin chye ai magri alloy welding manghkang ni
1. Electrode hpe shinggrup da ai
Byin masa:
- Interface kaw grai katsi ai
- Electrode hpe n-gun ja shangun ai (sh) awu asin byin shangun ai
Hpaji jaw ai lam ni:
- Tungsten n-gun dat ni hpe jat bang u
- Current hpe shayawm u / weld aten hpe shayawm u
- Katsi ai hpe grau kaja hkra galaw nna, electrode hpe ayan chywi u
2. Weld n-gun n law ai
Byin masa:
- Katsi ai gaw grai lawan ai hku bra mat ai
- Nugget n kaja ai rawt jat lam
Hpaji jaw ai lam ni:
- Squeeze n-gun hpe jat ya u
- Weld aten hpe loi mi jat ya u
- Welding hkang ai kaw na n galai shai ai pru ai lam hpe sadi u
- Bungli galaw ai shara hpe grau atsawm sha jasan jaseng u .
Kaja dik ai ladat ni gaw, n galai shai ai magri alloy weld quality a matu
- aten galu ngang grin ai hte bai galaw lu ai lam hpe makawp maga na matu:
- Arung arai-laksan parameter curve ni hpe galaw u
- Electrode ni hpe ayan jep yu nna bu hpun u .
- Alloy batch nnan shagu a matu chyam dinglik weld ni hpe galaw u
- Awng dang ai parameter hpawng de ai lam ni hpe ka matsing da ai
- Weld ya aten, n-gun, hte nugget kaba ai lam ni hpe yu maram yu u
Ndai ladat ni gaw mass-production makau grup yin hta hkrat sum ai lam hpe grai shayawm ya lu ai.
Quality hpe kam hpa ai lam hte chyam dinglik ai lam ni
Weld kam hpa mai ai lam hpe jep chyoi na matu:
- Hten za ai chyam dinglik ai lam (hten run ai, n-gun ja ai, cross-daw hpe jep joi ai lam)
- Nugget diameter hte fusion hpe kam na matu peel chyam yu ai
- N-gun n rawng ai, n-gun n rawng ai, grai katsi ai hpe myi man hte jep yu ai
- Parameter n bung ai hpe jep joi ai lam hpe hkang ai hte galai shai ai
Ndai mahtai ni hpe ka da ai gaw, masat masa galaw ai madang hte mungkan ting na quality ra kadawn ai lam ni hpe hkan sa na matu karum ya ai.
