Laser welding of brass is a high-precision, automated process favored for its low thermal load, creating narrow and deep seams with minimal deformation. It overcomes traditional welding challenges (like TIG/MIG) by offering superior quality for brass fittings, machinery, and automotive parts. Key challenges include high reflectivity and zinc evaporation (leading to porosity), which can be managed with optimized power, speed, and sometimes, filler materials. 

Key Considerations for Laser Welding Brass:

• Challenges: Zinc has a lower boiling point than the melting point of copper, causing high evaporation, potential porosity, and cracking.
• Process Parameters: High welding speeds and high power are generally required to manage the thermal conductivity and prevent defects.
• Applications: Ideal for joining thin-to-thick brass components in industries such as plumbing, electronics, and automotive.
