Part
Energy-storage module enclosure
Carbon-steel sheet-metal housing with multiple seams and distortion-sensitive assembly geometry.
Application Proof Brief · Energy Storage
Carbon-steel module housing welding with controlled sequence.
A compact sheet-metal enclosure application where seam repeatability, gap control, low deformation, and production handoff determine whether robotic autogenous laser welding is the right route.

Process route
Robotic autogenous laser welding
A fast, low-heat-input path when the joint preparation and gap stay inside the validated window.
Primary risks
Gap, sequence, heat accumulation
The cell must control part location and weld order before speed claims become meaningful.
Proof Plan
Validate the manufacturing window, not one perfect coupon.
A useful proof uses representative panels at normal tolerance and records the relationship between joint fit-up, welding sequence, finish, and inspection.
| Gate | Input | Evidence expected |
|---|---|---|
| Fit-up | Actual thickness, coating condition, bend tolerance, and maximum gap. | Joint map showing which seams can remain autogenous. |
| Fixture | Datum strategy, clamp access, loading direction, and part variation. | Repeatable seam position without hiding the weld path. |
| Sequence | Seam order, path length, heat accumulation, and tack strategy. | Panel flatness and seam consistency across the full housing. |
| Inspection | Visual, dimensional, sealing, section, or strength requirement. | A concise pass/fail report tied to the agreed acceptance method. |
Evidence Boundary
Commercially useful because uncertainty is visible.
- The application and process route are supported by collected shop-floor case footage.
- No cycle-time, deformation, leak, or yield figure is published without a traceable test record.
- If production gaps exceed the autogenous window, wire feed or joint redesign may be the correct route.
- The proof result should decide service production, fixture development, or a full robotic cell.
Next Step
Send the flat pattern, folded part, seam map, gap range, and inspection target.
Engineering will return the missing-information list and first proof recommendation before system selection.
