Effect of Dynamic Preheating on the Thermal Behavior and Mechanical Properties of Laser-Welded Joints
The high cooling rate and temperature gradient caused by the rapid heating and cooling characteristics of laser welding (LW) leads to excessive thermal stress and even cracks in welded joints. In order to solve these problems, a dynamic preheating method that uses hybrid laser arc welding to add an...
