...Farhang Farrokhi; Benny Endelt; Rasmus S. Andersen; Morten Kristiansen Grain refinement and the avoidance of columnar solidification is a great challenge in the deep penetration laser welds of thick-section steels. Further knowledge about the heat distribution and the temperature gradients in laser...

... of these cracks, it is the inevitable and localized increase in temperature and the ensuing thermal stresses that usually cause the damage. To help avoid the use of a separate preheating step, while at the same time allowing for faster joining, a unique method of dual-beam laser welding was developed...

... parameters. A more rigorous design approach is not commonly used primarily due to the complexity of laser welding, where small material or process parameter changes can greatly affect the weld quality. The model developed in this paper also enables optimizing operating parameters while providing monetary...
