Comparison of selected functional properties of laser energy sources using for welding processes
Main Article Content
Abstract
This article discusses the basic types of laser energy sources using in welding and related processes, such as surface modification and cutting. It presents the fundamentals of photon beam generation in various types of welding lasers. A general comparison of their selected technological and operational properties, including energy efficiency, wavelength, beam quality, photon beam transport method, operational durability, investment cost, operating cost, and service complexity, is provided. Recommendations for selecting laser welding methods for industrial applications are provided based on economic and technical considerations.
