Blasting-Induced Distortion
Abrasive-induced distortion is an undesirable deformation of thin-walled sheet metal structures due to one-sided mechanical stresses during blasting. It requires symmetrical blasting strategies to compensate.
Physical-Chemical Mechanism of Action
Blasting media-induced distortion occurs when the sheet wall is not uniformly loaded during blasting. This leads to one-sided mechanical stresses that deform and roughen the material.
Metallurgical Relevance & Welding Risks
Uneven distortion can lead to cracks, destruction of the sheet wall, and poor surface quality. This affects the mechanical properties and service life of the component.
Workshop Practice & Instructions
To avoid blasting media-induced distortion, symmetrical blasting strategies should be used. This means that the blast should hit the sheet wall from both sides simultaneously. The angles and distances of the blasters must be precisely adjusted to ensure uniform loading.
