In manufacturing, maintenance, repair, and overhaul (MRO) of aerospace components thorough cleaning is usually required. Examples include for example cleaning before coating, surface polishing or roughening, cleaning before any joining operations such as welding or brazing. MRO often requires coating stripping. Three main technologies are currently used: abrasive grit blasting, abrasive water jetting and chemical cleaning/stripping. All these technologies produce negative impact on environment and health. On top of that, they are slow and expensive. The intent of this talk is to present laser cleaning solution that intended to replace these legacy technologies. Laser cleaning/ablation is known in the industry, but the use is limited due limited access to correct laser sources and a concern of part damaging by laser heat.
This presentation will demonstrate successful applications of laser cleaning to different cleaning/ablation tasks that improve productivity and repeatability (as laser cleaning can be fully automated), direct cost savings and part performance improvements (quality).
