Evidenzbasierte Pädagogik – ein Déjà-vu?ry process parameters such as welding speed and consequently the heat input. Metallurgy and component design are however hardly ever considered due to special production requirements and therefore, restricted flexibility in material selection and design. Such conditions, especially crack-critical we

Evidenzbasiertes pädagogisches Handeln-fracture (STF) test method that was developed at Ohio State University by Nissley and Lippold (Welding J 82(12):355–364, 2003 [.]). Alloys 200, 600, and 625 were tested over a range of strain at 950 °C to determine the threshold strain for fracture (ε.) and the cracking response as a function of st

Evidenzbasierte Pädagogik – ein Déjà-vu?aint testing system for laser beam welding (LBW transverse-Varestraint test) was newly constructed. The timing-synchronisation among the laser oscillator, welding robot and hydraulic pressure devices was established by employing high-speed camera observation together with electrical signal control a

Einleitung: Wirtschaftliche Rationalitätt. The PVR test was used to determine susceptibility to cracking. This test uses forced deformation of specimens being welded at a variable rate where the criterion of sensitivity to crack formation is the presence of cracks and their number at the specimen surface as a function of the rate of force

Einleitung: Wirtschaftliche Rationalitätaser beam welding optimization of Al-Cu thin sheets using high brightness lasers. Joints were produced with welding speeds as fast as 12 m/min, characterized both mechanically and electrically, with microstructure analysis. The results exhibit that when Al is on top of Cu, the weld volume is large a
