Abstract
Laser cladding technology is widely used to recondition the condemned products. Some kind of damages can be brought about, due to the influence of high-energy laser and the addition of a new material. In this contribution, static strength and fatigue strength properties of different laser-process-based specimens were investigated. The result shows that both laser energy and the clad material have a negative influence on the applied workpiece. Both static strength and fatigue strength of the applied specimens decrease a lot, especially for laser cladding repaired specimens. Consequently, thermal damage which is characterized by strength deterioration is deemed introduced in the thermal process. According to this study, the damage is mainly attributed to material imperfection, residual stress state and hardness profile.
