Fiber laser welders generate a high-intensity beam within a doped glass fiber and deliver efficient, low-maintenance laser energy for precision welding. AMADA WELD TECH offers fiber laser welders with output powers from 250 W to 1 kW to address a wide range of metal welding applications including steel, nickel alloys, titanium, aluminum, and copper. Fiber Laser Welders — Overview A fiber laser is generated within a flexible, doped glass fiber that is typically 10 to 30 feet long and between 10 and 50 microns in diameter. The primary doping element is usually Ytterbium (Yb). How Fiber Laser Welders Operate Fiber laser welders generate a high-intensity beam within the doped optical fiber. This beam is delivered to the workpiece where it rapidly heats the material, typically within milliseconds, forming the weld. Laser welding is a non-contact process that requires access to the weld zone from only one side of the parts being joined. Benefits of Fiber Laser Welders Because of their efficiency and solid-state design, fiber laser systems can be smaller and require less maintenance than other laser technologies. Advantages include: High electrical efficiency Compact, air-cooled designs Low maintenance requirements No need to align cavity mirrors No optics alignment or maintenance Fine focus capability Adjustable beam quality to match specific welding applications Laser Welding Process Types Fiber laser welders can produce three primary weld types: Conduction Welds Performed at low energy Produce wide, shallow weld nuggets Conduction/Penetration Welds Use medium energy density Create deeper weld nuggets
