Yes, it is highly recommended to use a welding helmet for laser welding.
Even though laser welding does not produce the same intense, bright light as traditional welding methods, it can still generate harmful levels of ultraviolet and infrared radiation. Wearing a welding helmet protects the eyes and skin from potential damage caused by the welding process.
In addition to safety benefits, using a welding helmet provides clear visibility of the welding area, allowing for more accurate and precise work. As such, using a welding helmet is a vital component of safe and efficient laser welding practices.
