Chapter 1 – Understanding Lasers and Potential Hazards

This chapter introduces you to the basics of laser technology, emphasizing the unique characteristics of laser light compared to traditional light sources. You will learn about the coherence, directionality, and monochromatic properties of laser beams, which are crucial for understanding their applications and hazards in welding. The key risks associated with invisible infrared lasers, such as unintentional exposure and eye damage, are covered in depth. Key takeaways include the critical need for protective measures, such as safety goggles and proper workspace setup, to shield against these invisible hazards. By the end of this chapter, you’ll understand why rigorous safety protocols are essential in any environment where lasers are used.
