Abstract

The cutting performance of concrete using a laser-based hybrid technique was investigated. Experimental conditions included 7 kW laser power, 10 mm laser beam diameter, and 1.25-50 mm/s scanning speed. Results of surface scanning tests and 100 mm deep cut tests indicated that the shortest operation time was about 5.5 hr/m² for plain concrete and 7.2 hr/m² for heavy concrete.
