Factory Acceptance Checks for a Robotic Gantry Welding Workstation
How buyers can define practical pass or fail checks for a robotic gantry welding workstation, using travel, envelope, and synchronized-axis data as reference points in the FAT.
A buyer specifying a robotic gantry welding workstation should decide early whether the factory acceptance test will verify geometry and motion before weld quality, or treat both as one combined pass or fail gate. Splitting them usually gives clearer evidence: a travel or synchronization fault should not be hidden behind a weld inspection result.
For geometry, ask the supplier to demonstrate commanded movement across the stated standard effective X travel of 13,500 mm and effective Y / Z travel of 2,400 / 1,500 mm, and to show how the reference maximum workpiece envelope of 13,500 × 3,500 × 2,000 mm is checked. Treat these catalog values as reference figures, not as a promise for every supplied model. Define pass criteria in advance: measured positions within an agreed tolerance, no fault stops, and repeatable return to reference points.
For motion, require a demonstration of all 9 synchronized axes under a representative steel welding program. Ask what constitutes failure: loss of synchronization, uncommanded stops, or deviation beyond the agreed tolerance. For weld checks on steel, agree sample coupons, inspection method, and acceptance limits before the test rather than after seeing results.
Before requesting a quote, confirm with the supplier which tests are performed at the factory, what instrumentation and records are provided, how tolerances are defined, and whether the quoted configuration matches the travel, envelope, and axis figures used in the acceptance criteria.
