Laser Source Selection for Welding Applications

This guide outlines the selection of laser sources for welding applications, detailing various types of lasers and their specific characteristics. It explains that the choice of laser source has expanded significantly over the past 15 years, moving from traditional options like pulsed Nd:YAG and CO2 lasers to include fiber, diode, and disk lasers. The document categorizes laser sources based on their application suitability, including factors such as material, joint geometry, weld penetration, speed, and budget. It provides a detailed comparison of different laser types, including their penetration limits, beam delivery methods, and typical power ranges. Additionally, the guide discusses the importance of understanding the specific requirements of welding applications, emphasizing that the selection process should consider factors like weld width, heat input, and fit-up tolerances. The document also highlights the operational differences between fiber and pulsed Nd:YAG lasers, particularly regarding consumables and serviceability.
