Abstract
In the repair works of Japan’s infrastructure maintenance and management, there is a need to develop a technology that can easily remove coating and rust without a thermal effect on the base material, and the laser blasting technology, which can achieve this by only emitting laser beams, is a candidate for this goal. In various fields of infrastructure maintenance and management, we have been progressing on an agile system product development based on customer’s feedbacks in accordance with our in-house systematized new business development process. In this report, we will describe the development of the “InfraLaser” system and the laser blasting technology, where we apply a high-power laser and the processing technology that we have cultivated. The laser blasting technology can remove coating and rust faster than existing methods without affecting the base material, and is expected to be friendly to both workers and environment.
