Fehlmontagen
Fehlmontagen are faulty or incorrect assemblies, referring to mounting or installation errors in which components are assembled inappropriately, incorrectly oriented, misaligned, or with incorrect fasteners. Such errors can occur in mechanical, electrical, piping, or construction contexts and may compromise function, safety, or longevity. In German industrial usage the term encompasses both human mistakes and process deficiencies that lead to non-conforming installations.
Causes of Fehlmontagen include unclear or inconsistent assembly instructions, miscommunication between design and production, inadequate fixturing
Consequences are varied and potentially severe: functional failure or reduced reliability, premature wear, leaks or pressure
Typical examples span several domains. In mechanical systems, improper mounting of bearings or gears can cause
Prevention and detection focus on robust processes: clear, version-controlled mounting instructions; standardized work, checklists, and fixtures;
