Types of Laser Plastic Welding

Types of Laser Plastic Welding

Laser Plastic Welding is a cost-effective way to create precise and reliable plastic joints. Used in the production of automobiles, consumer goods and medical appliances, it involves components of varying shape and sizes, and requires different processing.

Do you know which type of Laser Plastic Welding is most suitable for your workflow? 

Quasi-simultaneous Welding

A single laser beam makes multiple passes over the joint very quickly, heating up the entire joint. The high speed laser melts the material along the seam, causing the components to join seemingly at the same time.

Contour Welding

A laser beam moves along the entire joint pattern, usually only once. The laser is guided by a robotic arm that allows the laser to travel in three-dimensions.

Radial Welding

In radial welding, the laser passes multiple times along the joint in order to heat up the seam.

Laser Transmission Welding

In normal laser welding, one layer needs to be laser-absorbent. The LPKF ClearJoining procedure uses laser transmission to allow for two laser-transparent materials to be welded together, producing clear joints.

3D Wobble Welding

A special welding process for large components with variable welding seams (between 1mm and 5mm). The change in welding seams is automatically calibrated with machine-specific software.

Hybrid Welding

LPKF hybrid welding uses special halogen spotlights to provide additional energy in the welding zone. This increases the process speed, produces high-quality weld seams and reduces stress.
