Robot use describes a production method; it does not by itself prove weld quality, strength or identical output between batches. These depend on design, settings, material, operator controls and verification records.
Request drawings, part codes and acceptance criteria for welded subassemblies in the offer. Check an initial sample and the same part from a later lot at matching measurement points; link critical dimensions, visible defects and coating/finishing records to the lot.
Agree a sampling plan and non-conformance notice path in writing beforehand. Record part code, lot, measuring tool and inspector alongside photographs. Do not treat robot use as a substitute for independent quality evidence or proof of product life.
