Laser welding of plastics is a method that has become more common and accepted in industry applications in the last couple of decades. It has several advantages over traditional methods, which include applying external heat sources, generating heat through mechanical movement, and certain other electromagnetic techniques.
CO2 lasers are used for making joints at high speeds, but the working depth is quite small, limiting their use to plastic films. For welding of thicker non-transparent polymers, Nd:YAG and diode lasers are much more suitable. The working area is very precise and concentrated, creating a seamless joint. Lasers emitting at 2 µm combine the mentioned advantages and are very attractive for transparent polymers.
Additionally, 2 µm lasers are nominally eye-safe.
Futonics fiber lasers are ideal for welding a variety of clear and colored thermoplastic materials.
High precision welding that results in accurate joint formation
No contact between the welding source and plastics
No marking of the outer surfaces
No need for additional plastics, implants or pigments at the joints
No need for additives
Butt-joints are realized
Eye-safe compared to other laser-assisted welding operations
