At the same time, manual operation is inefficient and cannot meet the needs of large-scale industrial production. In the welding powder batching and pressure coating process, the accuracy of manual batching is poor, which can easily cause uneven welding powder composition and affect the welding performance of the welding rod; and it is difficult to ensure consistent coating thickness when manually pressing welding powder, which reduces the stability and reliability of the product.
