Laser - Removal of corrosion products
Are there cases where laser ablation could replace the use of sand blasting? This case is a perfect example of where laser ablation comes to its right.
The challange was that a flange needed to be cleaned during shut down, and several activities was ongoing nearby to the equipment. Normally, the customer would use blast cleaning as a standard procedure for this type of repair. The consequence would be that surrounding activities would be paused, and a risk of dust and steel sand on surrounding equipment.
The customer chose laser as the cleaning method for the flange. The blast cleaning was estimated to use 5 times the time for the job. The cleaning was completed in one shift without affecting surrounding working processes.
