In the present paper, the laser beam weldability of ABS plates is determined by combining experimental and theoretical aspects. In modelling the process, an optical model is used to determine how the laser beam is attenuated by the first material and to obtain the laser beam profile at the interface. Using this information as input data in a thermal model, the evolution of the temperature field...

Very important property of powder metallurgy parts is ability to join components produced by different manufacturing technologies or dissimilar materials. Properties Nb modified HK30 are highly influenced conditions applied during sintering. Weldability sintered can be improved using favorable sintering conditions. In this regard, effect parameters on fusion weldability presented in paper. Inve...

Robotized laser welding is an application, which requires high speed combined with high precision. Realistic Dynamic Simulations combined with Off-line Programming, significantly enhances the a priory prediction of the weldability of a specific product. Obviously, realistic dynamic simulations require realistic models of the robot and controller. A 3DOF robot model has been formulated which inc...
