A wide range of options is available for ensuring quality and monitoring the joining process during laser plastic welding. Even before welding, necessary part properties, such as laser transmission, can be easily and reliably checked (see also article Quality assurance II). During the joining operation, the process parameters are continuously…
In order to keep defect costs in production low, it is useful to detect defects from pre-production before the welding process so that the corresponding components can be sorted out. In laser welding, by far the most frequent cause of defects is due to highly fluctuating transmission values of the…
Thanks to their superior properties, such as high temperature and chemical resistance, low weight and dimensional stability, high-performance polymers – such as PPA and PPS – are increasingly replacing assemblies made of metal and conventional engineering plastics. In the automotive industry in particular, this trend is being boosted by the…
Laser welding of plastics is a very robust and reliable process. The causes of defective welds are mostly found in pre-processes along the value chain. Already in the first step, the compounding, the material components and thus the important optical properties are determined. Although the usual fluctuations in this step…
Today, the laser is an established tool in many areas of production. Due to its high precision, the locally well-dosable energy input and last but not least its cleanliness, this tool has secured itself a firm place in production. Laser plastic welding in particular is particle-free, making it a key…
