Scientific novelty
Utilizing magnetic abrasive finishing as a preparatory operation for aluminum product edges before welding ensures uniform removal of contaminants and oxide film, while facilitating the regrowth of an oxide film with reduced thickness, volume, and hardness.
Advantages
The practical application of magnetic abrasive finishing for edge preparation of aluminum alloy products achieves required surface roughness, ensures removal of foreign inclusions and contaminants, and maintains a chemically inactive surface. This cold processing method removes the oxide film—which has a significantly higher melting point than the base metal—from the edges and prevents its rapid regrowth, thereby preventing foreign inclusions in the weld root caused by unmelted oxide film particles.
Commercial implementation
Applicable at mechanical engineering and energy sector enterprises to ensure defect-free welding of aluminum materials, increase product durability, and automate edge preparation. Testing of this processing method at JSC Elektroapparaty and PO Elektromashiny (Saint Petersburg) demonstrated its effectiveness in improving the quality of welded aluminum alloy products.
