Oxidation Stains Removal from Stainless Steel Flanges using Laser
Manufactures over 40,000 stainless steel barrels annually on its
production line. Stainless Steel Flanges ( such as butt joints and lap joints )
must be cleaned to remove oxidation from stainless steel during the
manufacturing process. For stainless steel weld cleaning to be
corrosion-resistant, it must be passivated after laser cleaning stainless
steel..
As part of their production line, laser cleaning stainless steel
was implemented in 2018, replacing conventional cleaning methods. As soon as
barrels come out of the machine, they are welded with oxide-free joints that
are repeatable.
High-power continuous-wave laser (CWL) transmitters have been
developed to effectively remove oxidation from stainless steel corrosion
products from severely corroded steel structures. Dry laser cleaning (DLC) and
wet laser cleaning (WLC) of the drench, soak, and rinse methods are employed to
compare the clean-up effect with conventional blasting methods.
Three-dimensional scanning electron microscopy, laser scanning
spectrometry, and scanning electron microscopy–energy dispersive X-ray
spectrometry are used to analyze the morphologies and chemical compositions of
untreated and treated surfaces. According to the results, laser surface
cleaning technology can effectively remove corrosion products and salts that
severely corrode steel members, as well as prolong the time before corrosion
returns.
Through laser irradiation, WLC can achieve excellent microscopic
cleaning and reduce the effect of high-temperature inputs on surfaces. Further
mechanistic analysis indicates that ablation, melting, and evaporation during
laser cleaning are primarily responsible for the removal of corrosion products
and salts. Consequently, the WLC drench method yields the best surface
cleanliness and is suitable for engineering applications. By using
laser-cleaning techniques, severely corroded structures can be maintained.
WHY DID INOVAWELD CHOOSE LASER CLEANING?
Initially, stainless steel oxides were removed using conventional
methods (chemical and mechanical cleaning). Based on their analysis of their
production processes, they determined that cleaning was the bottleneck.
Their decision aimed at optimizing cleaning led them to identify
several pain points associated with the process: dust production, noise levels,
consumable costs and management, and a slow output.
Using an environmentally-friendly 3 kW CWL transmitter, corrosion
products were directly removed from steel surfaces of real structures. A study
was conducted to examine and analyze the morphologies and microstructures of
multi surface laser-cleaning under different treatment conditions. Here are the
main results, which can be used as steel removal rust and prevent corrosion in
steel structures.
These are the pain points they addressed through ir laser
cleaning.
