CleanTech: a useful tool to combat corrosion


Inspenet, November 28, 2023.

Laser Photonics Corporation , a leading global company in the industrial development of CleanTech laser systems for various materials, highlights a fundamental application of its systems.

Welds are frequently tested in industrial environments because they are crucial to the integrity of large components such as pipes, boilers and pressure vessels ,” said Wayne Tupuola, CEO of Laser Photonics. “If a weld fails, the consequences can be very serious. Professionals who require an effective method of industrial surface preparation can greatly benefit from the use of our laser technology, which minimizes the need for necessary stops that occur due to scheduled inspections.“.

In this regard, industry professionals use non-destructive testing (NDT) to evaluate the resistance of a weld or component and detect possible defects. Surface preparation and cleaning before testing are essential in NDT and CleanTech technology is presented as an effective tool to carry out this process.

Unlike other surface preparation methods, laser cleaning ensures that the substrate surface is not stained, bent or altered. This approach uses lasers to efficiently vaporize surface contaminants, achieving optimal surface condition for dye penetrant inspections and magnetic particle testing, two of the most common NDT methods.

Laser systems also enable the precise removal of corrosion, paint, soot, oil, grease and other contaminants prior to NDT inspections. Laser cleaning significantly improves the visibility of cracks and defects, unlike conventional methods such as grinding, which can hide defects and complicate testing. It is for this reason that more and more NDT training centers prefer laser cleaning over alternative processes.

About the CleanTech system

Laser systems are available in both portable and stationary models, with powers ranging from 50 to 3000 watts (a 4000 watt version is currently in development). These systems feature chamber sizes ranging from 3′ x 3′ to 6′ x 12′. Additionally, they offer the versatility of being installed on manufacturing lines within cabinets or operated by a robotic arm.

Laser systems are not only efficient in maintaining door hinges and locks, but they also remove salt water stains from metal surfaces. In addition, this technology is applied in selective cleaning and stripping processes, addressing access points, service closures and various applications in the maritime field.

Similarly, CleanTech laser cleaning technology, developed by Laser Photonics, stands out as being environmentally friendly, cost-effective and time-efficient. Its applications range from rust and paint removal to surface preparation and more. This innovative technology is presented as a highly effective alternative to conventional cleaning methods, such as sandblasting and other abrasive blasting techniques.
