Laser Cutting of Structural Members With High Powered ND:YAG User System
Abstract
The application of laser technology for cutting structural members used in ship building was investigated. The original program required the use of a 1.8 kW Nd:YAG CW laser. This was expanded to include a 2.4 kW Nd:YAG CW laser, as well as a 1.4 and 14 kW C02 CW lasers. Process parameters such as laser power, travel speed, cutting gas type and flow, and focusing optic were adjusted to determine the feasibility of each laser for cutting structural members. Results indicated that all lasers, except the 1.8 kW Nd:YAG laser, produced acceptable cuts at speeds greater than 20 IPM. However, each laser is functionally different and careful evaluation of an application (s) is required in order to determine the most suitable laser. For example, to process large structural members with a CO2 laser, a complex beam manipulation device is required. Processing the same members with a Nd:YAG laser requires fiber optic delivery. Both types of systems are commercially available.
