PRE-WELDING CLEANING OF NON-FERROUS METALS FOR AEROSPACE
01 Pre-Welding Laser Cleaning for Launch Vehicle Tank Structures
This process removes surface oxides, oil stains on aluminum alloys, titanium alloys, superalloys and other materials of launch vehicle tank cabin structures. The traditional manual scraping cleaning method has many drawbacks, including substrate damage, low efficiency, high labor intensity, severe dust and particle contamination. Laser cleaning replaces manual scraping and greatly boosts working efficiency!
02 Laser Cleaning for Tank Circumferential Welds
It substitutes manual scraping with high automation and high efficiency. Both manual cleaning and repeated cleaning are supported. The quality of cleaned welds is inspected and evaluated via scientific systematic testing. The cleaning process and equipment are the first of their kind in the industry and protected by patents.
03 Oxide Film Cleaning for Tank Bottoms
Used to remove oxide films and oil contaminants on the two ends of aluminum alloy tank circumferential weld workpieces before welding. Post-cleaning welding delivers weld quality meeting Grade I standard of QJ2698A-2011.
04 Pre-Welding Laser Cleaning for Metals
Mainly applied to strip natural oxide films and artificial anodized layers on aluminum alloys, stainless steel, superalloys and other metals. The equipment features high automation and intelligence, automatically invoking matching cleaning processes for workpieces of various specifications to elevate pre-welding cleaning quality and avoid welding defects.
05 Pre-Welding Laser Cleaning for Components
Designed for pre-welding cleaning of aerospace parts. After cleaning, the surface cleanliness reaches Sa3 standard specified in GB/T8923.1-2011, while retaining the original machining textures of workpieces.
