Welding nut is a kind of nut suitable for welding outside the nut. It is generally made of weldable material and is thicker and suitable for welding. Welding is equivalent to turning two separate parts into a whole, melting the metal at high temperature and mixing it. After cooling down together, alloys will be added in the middle, and the interior is the effect of molecular force, and the strength is generally greater than that of the parent body.
There are many factors affecting the welding quality of welding nuts. For manufacturers, the main ones are: the material of the welding nut, the form and size of the projection welding nut boss, and the surface cleanliness (natural color plus appropriate anti-rust treatment); In the welding process, the most important thing is to control three process parameters: electrode pressure, welding current and welding time. When the electrode pressure increases, the bumps are instantly crushed, the size of the welding nugget decreases or even disappears, the joint strength decreases, and the stability of the welding process is destroyed; if the electrode pressure is too small, on the one hand, the bumps cannot be crushed; The welding process produces spatter. The welding current should match the welding time appropriately. Generally, when the diameter of the nut bump is larger, a harder specification is used, and when the diameter of the bump is small, a soft specification should be used.
