Die-Aluminium hpe n-gun ja ai hku n-gun dat ai|Ra ai arung arai ni hte galaw sa wa na lam matsun ni

Die-cast aluminum (and aluminum alloys) hpe mawdaw, electronic, jak rung, hte npawt nhpang bungli ni hta grai kaja ai n-gun-to-hkum hkrang n-gun, n-gun n-gun hpe ninghkap lu ai, n-gun n-gun hpe hkam sharang lu ai majaw grai law hkra jai lang nga ai.
Raitim, ndai arawn alai ni gaw, die-cast aluminum hpe n-gang (sh) n-gang n-gang hta grau nna spot weld galaw na matu yak shangun ai. Madung mayak mahkak ni gaw:

• Katsi ai hpe shalai ya lu ai atsam kaba– katsi ai gaw lawan ai hku bra ayai mat nna, weld galaw ai shara hta n mai shinggyin la lu ai.
• Wan n-gun n law ai– grau law ai welding current ni ra ai.
• Oxide lawan byin pru wa ai– aluminum oxide gaw wan n-gun hpe n-gun n-jaw ai sha, ngang grin ai wan n-gun hpe pat shingdang ya ai.
• Npu na hka n-gun hte n-gun kaba ai thermal jat wa ai– electrode n-gun n rawng ai, hkrang n bung ai, n bung ai nugget byin wa na masa hpe jat ya ai.

Dai majaw, die-cast aluminum ntsa ngang kang ai, ngang grin ai spot welds ni hpe lu la na matu, aluminum a matu laksan hku nna gram lajang da ai arung arai ni ra ai.ninghkap ai welding.

2. Aluminium-laksan welder law law hta .shi hkrai shi galaw ai electrode hpun palawng chywi ai ladat ni.

2. Katsi ai ladat hte katsi ai hpe hkang ai lam

Aluminium spot welding gaw, n-gun grai ja ai n-gun hpe n-gun dat ni hta tawn da ya ai.

• Hka-katsi ai electrode ni hpe ra sharawng ai.
• Hka lwi na matu hpaji jaw da ai:0.5-1.5 gal/min (2-6 L/min).
• Electrode a n-gun hpe n-gun n-htum hkra hka n-gun hte n-gun hpe yu maram ra ai.
• Katsi ai shara ni hta, sadi u-katsi ai hpe makawp maga ya aihte hkra machyi ai lam n byin na matu hkrak ai system hka hpe hka ja ra ai.

Kaja ai katsi ai ladat gaw electrode a prat hpe grai galu shangun nna, weld a n-gun hpe grau kaja hkra galaw ya ai.

Hpa majaw nga yang, n-gun ja ai aluminium spot welding gaw, kaja ai arung arai ni hta sha n-ga, hkrak tup parameter hpe hkang lu ai hta mung madung nga ai.

Madung masat masa ni hta:

• Welding galaw ai

1. Aluminum gaw steel hta grau nna current ra ai.
2. ~1.2 mm aluminum sheet a matu, laksan hpaji jaw ai lam ni gaw:22,000-28,000 A (22-28 kA).

• Electrode n-gun

1. Stable contact hpe hkam la ra nna, nbung/oxide layers ni hpe n hkra hkra shinggrup kau ra ai.
2. Ideal n-gun gaw n-gun hte geometry hku nna shai hkat nna, fine-tuned galaw ra ai.

• Welding galaw ai aten

1. Jai lang aigrai kadun ai weld aten nialuminum gaw lawan ai hku katsi ai hpe shapraw kau ai majaw re.
2. Kaja wa nga yang, millisecond (ms) shi daram (sh) cycle loi mi sha re.

• Squeeze aten & Hold aten

1. Squeeze aten: current n lwi shi yang, dai daw ni hpe shinggrup da nna, oxide film hpe daw kau ya ai.
2. Hkap la ai aten: current hkring mat ai hpang, nugget ngang kang wa ai aten du hkra, pressure hpe matut manoi tawn da nna, weld n-gun hpe hkam la shangun ai.

• Law law lang-pulse / Lahkam law law-Welding galaw ai

1. Hpa majaw nga yang, n-gun ja ai, n-gun ja ai, shing nrai, n-gun ja ai die{1}}cast aluminum a matu, law law lang galaw ai ladat (pre{3}}heat → main weld → forge) gaw nugget a hkam kaja lam hpe grau kaja hkra galaw ya nna, n kaja ai lam ni hpe shayawm ya lu ai.

2019 ning hta hpaw na matu grai tsun shadut da ai.welding galaw ai aten ladawarung arai langai hpra a matu, n-gun, hte tooling setup ni a matu.

Aluminium hpe ninghkap ai spot welding a matu, hpaga lam hta masat da ai madang gaw:ISO 18595:2021 - Aluminium hte Aluminium hpe ninghkap ai shara kaw shinggrup ai lam Alloys

0.6–6 mm aluminum n-gang, n-gun dat, hte n-gun dat (die-htu shapraw ai aluminum lawm ai) ni hta jai lang mai ai.

Madung lam ni:

• ISO 5182 Class A2/2 zawn re ai magri mang n-gun dat ni hpe hpaji jaw ai.
• Bench welder ni, welding sinat ni, robot masa ni, hte multi-spot masa ni hta jai lang mai ai.
• Nugget kaba ai, n-gun ja ai, weld quality ni hpe chyam dinglik ai ladat ni hpe tsun dan ai.
• ISO-htap htuk ai arung arai ni hpe jai lang ai gaw, ngang grin ai galaw shapraw ai lam hpe loi ai hku galaw lu nna, QC ra kadawn ai lam ni hpe mung hkan sa lu na re.

1. Electrode hpe gram lajang ai lam

Aluminium gaw electrode ni hpe lawan ai hku awu asin di kau ya nna, nsam galai shai kau ya ai majaw, dressing (sh) resharpening hpe masat da ai aten ladaw ni hta galaw ra ai (ga shadawn, 500–1,000 weld shagu).

2. Katsi ai ladat hpe yu reng ai

Daw dan lam

Spot welding die-htu ai aluminum gaw n-gang htu ai hta grau sawng ai. Awng dang na matu ra ai:

• laksan electrode ni
• N-gun ja ai hka-katsi ai hte gram lajang ai ladat ni
• Tengman ai parameter hpe hkang ai
• ISO 18595 hpe hkan sa ai
• Matut manoi quality hpe hparan ai lam

Teng man ai arung arai ni, galaw sa wa ai lam hpe hkang zing ai, gram lajang ai lam ni hpe kahkyin gumdin ai hku nna sha, galaw shapraw ai ni gaw, grau nna mawdaw hte electronic zawn re ai ra kadawn ai lam law ai hpaga lam ni hta, die-cast aluminum ntsa hta ngang kang ai, bai galaw mai ai weld ni hpe lu la mai ai.
