Car oil tank (a tlangpuiin low-carbon steel emaw aluminium emaw hmanga siam) welding aseam welding machine hmanga siam a nitih chian nan precision a mamawhleak-proof, durable, leh crack-resistant seam te a awm. A hnuaia tarlan te hi step-by-step industrial guide a ni:

 


1. Material & Design buatsaih dan tur ruahmanna siam

  • Bungrua:

Steel Tanks: Weldability atan low-carbon steel (eg, SAE 1006/1010) hmang ang che.

Aluminium Tank: 3003/5052 alloy hmang la (7000-series hmang lo la).

  • Surface tihfai a ni:

Alkaline cleaner hmangin degrease → Abrasive brushing (steel) emaw chemical etching (aluminum) hmangin oxides te chu paih chhuak rawh.

  • Joint Design siam a ni:

Lap joint te nen10–12mm inkar a ni(seam welding atan) a ni.

Flange alignment a tuar theihna:±0.2mm a ni.


2. Seam Welding Machine hmanga siam a niRem khawm

Parameter a ni Steel Tank te a awm bawk Aluminium Tank te pawh a awm
Welding Current a ni 15–25 kA a ni 20–35 kA a ni
Electrode chakna a ni 3–6 kN a ni 2–4 kN a ni
Welding Speed ​​a ni 1–3 m/min a ni 0.5–2 m/min a ni
Pulse hun chhung 10–30 chhung (AC) a ni. 5–15 chhung (MFDC) a ni.
Cooling a ni Pawn lam tui jet te A chhunga electrode H2O tihlum

Thil chhinchhiah:

  • Thir: AC emaw MFDC (Medium Frequency Direct Current) emaw hmang rawh.
  • Aluminium a ni: MFDC chauh a ni(electrode a stick loh nan).
  • Electrode hmanga siam a ni: Cu-Cr alloy wheel (a zau zawng=1.5× sheet thickness).

3. Welding kalphung Flow

  • Fixture Loading a ni:

Clamp tank chanve vel chu arotary fixture hmanga siam a ni(circular seams atan) emawlinear tracker a ni(straight seams tan chuan).

  • Tack Welding a ni:

Spot-weld tawp ber chu50% power a nimisalignment awm loh nan.

  • Seam Welding a ni:

Electrode wheel te engage → Force hmang → Current pulse + wheel rotation tan tir.

Khirhkhan: Overlap spot hrang hrang by25–30%hermetic seal chhunzawm zel tur atan.

  • Post-Weld hmanga tihlum:

Distortion tihziaawmna turin weld zone chungah compressed air puak rawh.


4. Quality Check pawimawh tak tak

  • Leak Test a ni:

Pressurize tank chu a awm a0.5 bar a ni→ Tuiah tuiah pil rawh; bubble awm leh awm loh enfiah (100% inspection).

  • Tihchhiatna Test:

Sample cut → A tehnanugget zau zawng a ni(√j aia lian emaw, a tlukpui emaw a ni tur a ni, chutah chuan x=sheet thickness).

  • Visual/Dye hmanga lut thei:

Crack, porosity, electrode mark emaw a awm leh awm loh enfiah thin ang che.


5. Common Defects & Fixes awm thei te

Defect a awm Chhan Chhanna dik
Leak a awm Overlap/current hniam tak a ni ↑ Tunah hian 10%-in a awm a; ↓ speed 20% a ni.
Crater/Crack awm te Electrode enkawl that loh Weld 50 danah electrode dress siam thin ang che
Warping tih a ni Heat input tam lutuk ↑ Hman chakna; pulsed cooling hmang rawh
A rilru a buai em em a (Al) . Electrode alloy a inmil lo hle Cu-Zr electrode + MFDC hmang rawh

6. Automation Integration (High-Volume Production) hmanga tihchhuah a ni.

  • Robotic Seam Cell hmanga siam a ni:

6-axis robot te chu seam tracking laser hmanga siam (eg, FANUC ArcMate) te an ni.

  • In-Line Leak Testers te chu:

Automated pressure decay sensor → Tank chhia chu hnawl rawh<20 sec.

Auto-time resistance monitoring tak tak hmanga current/force siamrem.


7. Hriselna & Dan zawm dan

  • Ventilation a awm theih nan: Welding meikhu (steel: Mn/Cr oxides; Al: Al2O3) lakchhuah.
  • Standard hrang hrang:

ISO 3834 (fusion welding atana quality mamawh).

FMVSS 301 (lirthei tan fuel tank integrity) a ni.
