What is Laser Welding and How Does It Work? | Laserax
The two main types of laser welding processes—conduction welding and keyhole welding—work differently. Conduction welding is a soft process where the laser beam slowly melts the metal. During this type of welding, the metal''s temperature goes beyond its fusion point and achieves the liquid state but never goes into the gaseous state.
