This cell pairs a collaborative robot with a laser welder, tracking the battery-shell seam with high precision; concentrated, controllable laser heat and stable speed produce uniform, attractive, consistent welds. The payoff is direct: versus manual welding, quality and consistency jump while labor cost drops; on an EV customer’s battery-shell application, payback ran as little as six months.

The problem
Three pits of battery-shell welding. The shell is thin — a little excess heat warps it and leaks. Seams are long and cycle-tight, so manual speed and consistency trade off. And fast EV model changes mean re-training welders every time the seam path changes.
The solution
This cell pairs a collaborative robot with a laser welder, tracking the battery-shell seam with high precision; concentrated, controllable laser heat and stable speed produce uniform, attractive, consistent welds.
In detail
Laser welding’s small heat-affected zone resists warping on thin shells for a more reliable seal; high path accuracy keeps seams straight and even, with appearance consistency far beyond manual work.
Drag-to-teach plus a welding software package sets laser power, speed and start-stop in a few steps, with live process monitoring — no dedicated robot engineer needed to program.
The results
The payoff is direct: versus manual welding, quality and consistency jump while labor cost drops; on an EV customer’s battery-shell application, payback ran as little as six months.
Flexibility & changeover
Model changes are no problem: a new seam path is just a program change — small batches and many variants on demand — flexibly absorbing the fast EV cadence.

FAQ
What makes this different from manual operation? Three pits of battery-shell welding. The shell is thin — a little excess heat warps it and leaks. Seams are long and cycle-tight, so manual speed and consistency trade off. And fast EV model changes mean re-training welders every time the seam path changes.
What are the measurable results? The payoff is direct: versus manual welding, quality and consistency jump while labor cost drops; on an EV customer’s battery-shell application, payback ran as little as six months.
How hard is changeover to a new part or model? Model changes are no problem: a new seam path is just a program change — small batches and many variants on demand — flexibly absorbing the fast EV cadence.
