The role of angle grinder in removing oxide layer

During the welding process, the oxide layer will hinder the formation of the weld, resulting in a decrease in welding strength and defects such as pores and cracks. The oxide layer will also affect subsequent surface treatment, such as spraying, plating, etc. Therefore, before welding and processing, it is important to remove the oxide layer to ensure that the metal surface is clean. Angle grinders play an important role in removing oxide layers due to their high efficiency and flexibility.
Angle grinders effectively remove the oxide layer on the surface by rubbing the high-speed rotating grinding disc against the metal surface. The material and type of the grinding disc are crucial to the removal effect. Choosing the right grinding disc ensures that the oxide layer is removed while minimizing damage to the substrate.
The process of removing the oxide layer
Choosing the right grinding disc: When removing the oxide layer, a coarser grinding disc is usually selected to increase the removal effect. The material of the grinding disc should be adapted to the characteristics of the metal being treated.
Controlling the grinding pressure: During operation, the pressure applied should not be too large to avoid damaging the metal surface. Reasonable pressure can effectively remove the oxide layer while maintaining the integrity of the substrate.
Maintain proper angle: The abrasive disc should be kept at a certain angle to the metal surface during operation, which can maximize the contact area and improve the removal efficiency. It is generally recommended to maintain a tilt angle of 15-30 degrees.
Even movement: When treating the surface, you should maintain even movement and avoid staying in the same position for too long to avoid pitting or excessive wear.
