Advantages Of Projection Welding Nuts Compared With Welding Nut

Xinchi Fastener Company has introduced what welding nuts are and what projection welding nuts are, if you are interested in this, you can read our last two articles. This article will give you an in-depth look at the other advantages of projection welding nuts over welded nuts.

1. The projection welding nut can weld multiple spots simultaneously in one welding cycle, which not only has high productivity but also has no shunt effect. Therefore, the solder joint can be arranged on the narrow part without the limitation of spot spacing.
2. Because the current density is concentrated in projection points, the current density is large, so it can be used for welding with a small current, and can reliably form a small core. In spot welding, corresponding to a certain plate thickness, it is difficult to form a core less than a certain size.
3. The projection point of the convex welding nut is accurate, the size is consistent, and the strength of each point is uniform. Therefore, for a given strength, the projection welding point size can be less than the spot welding point.
4. Because the projection welding nut uses a large planar electrode, and the projection point is set on one workpiece, it can minimize the indentation on the exposed surface of another workpiece. At the same time, because of the small current density and good heat dissipation of the large planar electrode, the wear of the electrode is much smaller than that of spot welding, thus greatly reducing the maintenance and repair costs of the electrode.
5. The oil, rust, oxide skin, coating, and other coatings on the workpiece surface have little influence on projection welding compared with that spot welding, but the clean surface can still obtain more stable quality.

Because of the advantages mentioned above, projection welding has been widely used. The disadvantage of projection welding is that the additional process of punching projection welding and the electrode are more complicated. In addition, since projection welding involves welding multiple spots at a time, it is necessary to use high-power welding machines with high electrode pressure and high mechanical accuracy.
