Because of several advantages, e.g., an exact and high energy input, laser transmission welding has become more and more important in the last few years. Due to the contactless energy input, a sufficient process control is a challenge. In industrial production, the process parameters for a good weld seam are qualified by the energy input, which describes the process parameters laser power, laser velocity...
Laser transmission welding is one of the various welding techniques used to join thermoplastics. Low heat introduction into the welded parts and a high welding speed are the reasons why laser transmission welding established itself in the plastic processing industry. In all welding processes for thermoplastics, residual stresses occur due to the thermal expansion during heating and its resetting during...
