The use of narrow gap for thick component welding as applied in nuclear industries and especially by AREVA NP, requires the mastering of several parameters and especially shrinkage. The prediction through to numerical simulation is very helpful for welding procedure definition. This paper describes an approach used to determine a 3D heat source dedicated to a new industrial welding process configuration...
In today’s automotive frame-and-body construction, laser welds are typically carried out as square butt welds in lap joints. These welds are increasingly produced by remote laser welding optics with working distances of 500 mm and more. This enables simple path programming because clamping devices are traversed over and therefore low cycle times with improved productivity is achieved. However, workpiece...
