Fibre laser welding for packaging of disposable polymeric microfluidic-biochips
TLDR
In this paper, a new approach for the laser transmission welding developed for the packaging of disposable polymeric microfluidic-biochips is presented, which combines the characteristics of the polymer contour welding and quasi-simultaneous welding and allows the achievement of contamination-free, high quality weld seams as narrow as 100μm with a high dynamic.About:

Laser diode transmission welding of polypropylene: Geometrical and microstructure characterisation of weld
TL;DR: In this paper, the influence of process parameters, both the laser power and the welding speed, on the geometry and the microstructure of the weld zone were investigated, and it was shown that the increase of the laser powers and the decrease of the scanning speed lead to a larger volume of the welding zone with a more important depth penetration.

Effect of surface modification on laser direct joining of cyclic olefin polymer and stainless steel
TL;DR: In this paper, surface modification pretreatment on the laser-bonded joint between a cyclic olefin polymer (COP) and stainless steel (SUS304) was studied to determine its effect on improving the laser bated joint strength.
