A welding nut is a type of nut that is specifically designed to be welded onto a metal surface. Here is a detailed introduction:
A welding nut is a nut with a cylindrical or hexagonal shape, usually made of carbon steel or stainless steel. It has internal threads for engaging with bolts or screws, and its outer surface is designed for welding. The most common type has a hexagonal head, similar to a regular nut, but with additional features to facilitate welding.
The welding nut works by being welded firmly to a metal workpiece. Once welded in place, it provides a stable and secure threaded connection point. When a bolt or screw is inserted into the welding nut, the threads of the nut and the bolt interact to create a tight and reliable joint. This joint can withstand various forces and is commonly used in applications where a strong and permanent connection is required.
Types: There are several types of welding nuts, including projection welding nuts and spot welding nuts. Projection welding nuts have small projections on their surface that help to concentrate the welding heat and force, ensuring a strong weld. Spot welding nuts are designed to be welded using the spot welding process, where the weld is made at specific points.
Applications: Welding nuts are widely used in the automotive industry for attaching various components such as seats, brackets, and exhaust systems. They are also commonly used in the construction of machinery, metal furniture, and electrical equipment. In these applications, the welding nut provides a reliable and efficient way to create a threaded connection without the need for drilling and tapping holes in the workpiece, which can be time - consuming and may weaken the material.
Strength and Durability: The welding process creates a strong bond between the nut and the metal surface, resulting in a connection that can withstand high loads and vibrations. This makes welding nuts suitable for use in demanding applications where reliability is crucial.
Time - saving and Cost - effective: Compared to other methods of creating threaded connections, such as drilling and tapping, using welding nuts can save significant amounts of time and labor. This can lead to cost savings in manufacturing processes.
Versatility: Welding nuts can be used on a variety of metal materials and in different shapes and sizes, making them a versatile fastening solution for many applications.
In summary, welding nuts are an important type of fastening component in the metalworking and manufacturing industries, offering strength, durability, and efficiency in creating reliable threaded connections.

Application: disc welding nut is used in metal connection, which is an economic and effective connection. The main materials are carbon steel and stainless steel. There are three kinds of welding nuts, which are common disk welding nut, disk welding nut with hole and disk welding nut with spot. The design of the disk with hole can make the nail or screw firmly fix the material from it, and can provide a fulcrum when the nut is casted into the plastic. However, the design of the disk with welding points is mostly suitable for spot welding connection. There are three to four welding points on each side of the circular base flange, which can prevent the flange edge from rotating in the hard metal connection.
Application: flat welding nut mainly refers to the welding nut with square or strip base, mainly made of carbon steel and stainless steel. There are three kinds of welding nuts: ordinary plate welding nut, plate welding nut with hole and plate welding nut with spot. The base of the flat welded nut with holes has two round holes, which can make the nail or screw firmly fix the material, and can provide a fulcrum when the nut is casted into the plastic,. The design of flat strip welding points is mostly suitable for spot welding connection. There are two to four welding points on each side of the circular base flange, which can prevent flange edge from rotating in the connection of hard metal.
