Joint quality can mean a variety of different things depending on who is asking and for what application. A quality weld to one engineer could mean a strong hermetic seal and to another it could refer to a clean and consistent weld for aesthetic reasons.
This article will focus on weld quality in reference to strength and seal.
If you are familiar with laser plastic welding you understand that the upper layer needs to be transparent to the radiation and the lower layer absorbent to the same radiation.
The majority of thermoplastics transmit common laser welding wavelengths in their natural state, but a variety of factors influence the level of transmittance, including: thickness of the plastic, fillers (glass or fiber), flame retardants and color additives.
This article will focus specifically on how color affects the process.
We are currently developing educational content (webinars/case studies) for laser plastic welding. What topics would you like to see covered?

Quality control is a main factor in the development and manufacture of any new product. From pre-production testing to in-line process monitoring, control mechanisms often drive much of the process of bringing a product from concept to production.
See the ins-and-outs of a standard, stand-alone laser welding system. Designed for heavy industrial use the, LPKF LQ-Power is a workhouse, but still lives up to the “velvet hand” precision laser welding is know for. The rotary indexing table allows for parts to be loaded during welding, reducing downtime.
Laser plastic welding of car tail lights is the next big thing in automotive manufacturing for good reasons including: durable and hermetic seals, aesthetically pleasing weld seams, flexibility and cleanliness. Pushing this already ground breaking technology even further, LPKF Laser & Electronics has introduced a hybrid welding system.
Balloon dilation catheters used to expand the coronary vessels must not only be leak-proof but are also subject to tight tolerances. A CO2 laser integrated into a welding system ensures the requirements are implemented in series production, while making for a robust process that offers short cycle times.
A powerful document for engineers designing applications for laser plastic welding. Covers the main factors affecting a quality weld, material considerations, process types and more.
Laser plastic welding is becoming well known for its ability to join complex and detailed parts. In fact, the technology is driving innovation for products that were once not possible in the medical, automotive and consumer electronics industries.
However, there still exists a stigma that laser technology cannot compete economically with other joining methods. Despite the technical advantages, the initial capital investment of laser systems has been a stumbling block for the technology.
Quality starts with a safe and reliable welding process, and continues with proper testing. The LPKF LQ systems boast integrated process monitoring including regulation mechanisms which correct even the smallest deviations.This brochure highlights the process monitoring capabilities of laser welding systems.
