WinAck RS3000G four-axis battery busbar laser station
The WinAck RS3000G welds busbars to battery terminals using a continuous-wave fibre laser, a galvanometer head and a four-axis gantry. A height sensor and pneumatic pressing hold the joint at focus. This configuration runs at 3 kW, with 1000–6000 W sources offered as options for EV, ESS and pack lines.

Gantry travel, workpiece size and laser source
The gantry travels X800, Y1 600, Y2 600 and Z400 mm, and the largest workpiece is 600 ×400 ×400 mm. Longer travel can be built to order. Ask WinAck what each Y axis does and mark the reachable weld area on your fixture drawing, since axis travel and usable module size differ. Agree the contact method and force for the pneumatic press that holds busbar and terminal together.
GW Laser supplies the standard CW fibre source, with Raycus, Maxphotonics and IPG as alternatives. This configuration uses 3000 W average power, and 1000–6000 W versions are optional. Name the source brand and power on the quotation. Wavelength is 1080 ±10 nm and power adjusts from 10–100%; penetration and heat input on your material pair come from weld trials.

Height sensing, positioning and the CCD question
WinAck lists a height sensor with 30 µm repeatability, gantry positioning accuracy of ±0.05 mm and repeat positioning of ±0.02 mm. Each figure belongs to a different function, and seam placement on the part depends on all of them plus the fixture. Define the height reference, focal position, module tolerance and clamp deformation at your actual weld points.
The feature list calls positioning CCD optional, yet the main configuration table includes one MindVision CCD. Ask WinAck to state whether vision is in the delivery. If it is, see imaging, coordinate calibration and offset correction work on real parts. The software stores recipes, follows CNC or taught paths and sets power by area; request a written recipe and change-control procedure for it.

Weld trials, cooling, gas and guarding
Welding speed runs 10–100 mm/s, which is a seam speed and differs from module output. Trial your own busbar, plating, terminal material and joint gap. Agree methods for joint resistance, strength, penetration, spatter and allowed cell heating. WinAck names EV, ESS, pouch and cylindrical packs as applications; qualify the specific case and terminal combination you will build.
Cooling is by water at 25 ±3°C, and an air knife protects the optics. Supply compressed air at 0.6 MPa or more and 30 L/min, and optional nitrogen or argon at least 0.4 MPa at 15 L/min. The station runs on 380 V ±10% three-phase at 50 Hz, and the floor must carry at least 600 kg/m². Size the chiller, fume extraction, laser enclosure, interlocks and viewing windows for the installed cell. The reference picture shows an open machine, so specify the full guarded enclosure in the order.
WinAck's profile lists the sorter that groups cells before welding, and the FAT and SAT page shows how to qualify busbar joints.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Does the fixture fit the reachable weld area? | Axis travel is X800/Y1 600/Y2 600/Z400 mm; the largest workpiece is 600 ×400 ×400 mm. | Approve gantry, clamp and weld-coordinate drawings. |
| Is CCD position compensation included? | The feature list calls CCD optional; the configuration table includes one. | Fix the delivery list and see calibrated vision run if fitted. |
| Which power and speed produce an acceptable joint? | The catalogue lists 3000 W and 10–100 mm/s with no busbar weld results. | Trial your stack and agree electrical, strength and thermal limits. |
