NTC Sensor Welding for Lithium-Ion Packs

Modern EV and energy storage battery packs carry dozens of NTC thermistors per pack for cell-level temperature monitoring. Layjun Welder TC-300A attaches sensor leads at 1,800–2,400 joints per hour with argon-shielded, fully repeatable welds — and serial-number traceability for every joint.

  • ✓Wire: 28–30 AWG stranded sensor leads
  • ✓Ni-plated Cu, brass and steel terminals
  • ✓Inline pull test 10–50 N per joint
  • ✓Argon-purged welds, -15°C to +50°C rated
  • ✓MES/ERP integration (OPC-UA, MQTT)

Power Generation & Refining

Thermocouple Probes for Turbines, Boilers & Refineries

Power plants, petrochemical refineries and incinerators run on K, N and R/S-type thermocouple probes assembled in the thousands. Layjun Welder benchtop welders — especially the heavy-gauge TC-100B — produce hot-junction welds with the repeatability that IEC 60584 Class 1 tolerance demands.

  • ✓Heavy-gauge wire up to 5.0 mm (TC-100B)
  • ✓K, N, R, S and B type junctions
  • ✓IEC 60584 Class 1 tolerance support

Solar PV Junction Boxes

Bypass Diode and Wire Welding for PV Modules

Photovoltaic module junction boxes contain bypass diodes that protect cells from hot-spot damage. Layjun Welder CD welders reliably attach lead wires to diode packages and ribbon-to-junction-box connections for solar panel manufacturers.

  • ✓Compatible with TO-220, TO-247 diode packages
  • ✓Cu and Al ribbon up to 6 mm wide
  • ✓UL 1703 / IEC 61730 process documentation
