High-low angular distortion
Edge offset induced angular distortion occurs when sheet edges are not flush during joining and create asymmetric cross-sectional stresses. This leads to distortion of the weld.
Physical-Chemical Mechanism of Action
Sheet edges that are not flush during joining cause asymmetric cross-sectional stresses. These stresses lead to distortion of the weld in the form of angular distortion.
Metallurgical Relevance & Risks during Welding
Edge offset induced angular distortion can lead to the development of cracks and hardness problems. The weld is deformed, which affects the mechanical properties and reduces the lifespan of the component.
Workshop Practice & Instructions
To avoid edge offset induced angular distortion, the sheet edges must be flush during joining. This can be achieved through careful preparation and maintaining the correct gaps between the sheets. Checking the stress distribution is crucial.
