Rail fitting: welded, then machined to datum
A welded steel fitting for a rail system supplier, machined after welding so that functional features reference the finished structure.

Challenge
Welding distorts the structure. If functional faces and bores are machined before welding, they move. The route must place machining after welding, with datums that the customer’s assembly also uses.
Route
| Step | Where | Check |
|---|---|---|
| Cutting and preparation | Welding facility | Dimensions |
| Welding (MIG/MAG or robotic CMT) | Welding facility | On request |
| Machining of datums, faces and bores | 4-axis machining centre | In-process measurement |
| Laser marking | Main plant | Batch traceability |
| Final inspection | CMM | Dimensional report |
| Coating / painting | Approved supplier | Coating thickness |
