Russia’s Triniti uses mobile laser complex for metal dismantling

25 August 2021

Russia’s Troitsk Institute of Innovative and Thermonuclear Research (Triniti - part of Rosatom’s scientific division) and LLC Demolition jointly dismantled the metal frames of three bunkers at a closed down capital construction facility (plant) in Karelia using a mobile laser complex (MLK). The work involved the use of remote separation laser cutting. “The mobile laser complex was created as part of the implementation of Rosatom’s unified sectoral thematic plan (CSP), and this is the first product of the scientific division, which began to generate revenue for the enterprise even before the project was completed,” said Azamat Bedanokov, Triniti deputy director general for international and commercial activities. “The MLK can be used to cut metal structures up to 250 mm thick, both on land and under water, in the temperature range from -50 to 40 degrees Celsius.”

Triniti offers the manufacture of mobile laser systems in accordance with the customer's requirements, training of specialists, as well as services for renting an MLK and performing remote laser cutting of metal structures on a turnkey basis.

“Of course, it is important to apply innovative solutions in industry. Recently, we introduced the technology of diamond cutting, robotic dismantling, and used new attachments. Today, these are considered the norm, and specialised companies have the appropriate special equipment. The use of remote separation laser cutting is primarily due to safety - the container with the laser complex and the personnel are at a safe distance from the object of up to 100 metres. In addition, MLK is mobile, autonomous and economical, so we decided to use it in our work,” said Anton Tarasov, Development Director of Demolition LLC.

The development of territories requires the elimination of abandoned, obsolete and emergency industrial buildings. Unused metal structures are subject to complete or partial natural destruction, connections are deformed in them, so the demolition of such structures becomes unsafe. Dismantling of structures using construction machinery is carried out, albeit at a safe, but relatively close distance. This method requires the mobilisation of oversized large-capacity demolition excavators with long arms, which complicates their transportation and increases the cost of work. The method of remote separation laser cutting will save time and costs, while increasing the safety of the process of fragmentation and dismantling of metal structures.
