Weld Post Processing
Weld post-processing includes mechanical or thermal methods to improve the surface and optimize fatigue behavior. It removes notch effects and improves hardness.
Physical-Chemical Mechanism of Action
Weld post-weld treatment encompasses various methods such as polishing, chipping, or thermal treatment. These processes remove surface defects and notches, improve hardness, and increase the fatigue behavior of the weld.
Metallurgical Relevance & Welding Risks
Without post-weld treatment, notches can lead to cracks or failures. Insufficient hardness can impair fatigue behavior, leading to premature component failure.
Workshop Practice & Action Instructions
After welding, use mechanical post-weld treatment such as polishing or chipping to remove notches. For special applications, thermal treatment may be required. Pay attention to the correct temperature and time for post-weld treatment to achieve the desired hardness and surface quality.
