Shielding Gases for Laser Welding

Описание к видео Shielding Gases for Laser Welding

Shielding gases are used in laser welding for a variety of reasons including shielding the molten metal from the ambient, for washing away the soot, and for preventing nail-head formation in the weld zone. Shielding gas may not be required for high speed welding. While Argon is the most commonly used shielding gas, Nitrogen is also a good choice.
