A welding nut is a nut suitable for welding. It is usually made of welding material, so the thickness is more suitable for welding. Welding is the equivalent of fusing two separate parts, melting the metal together, and then cooling it. The alloy will be added to the middle. Inside are molecular forces, which are generally stronger than the parent body.
Hexagon welding nut
When welding, the strength is large, the application is wide, the thickness can be, but due to the high temperature will lead to the deformation of the connection, not removable, part of the activity can not be welded by traditional methods, welding parameter test depends on the fusion size of the weld, and according to the fusion size adjust the welding parameters until completely eliminated. Of course, the quality of welding depends on pre-welding treatment, ash removal, oil pollution and so on.

What is the difference between a welding nut and a hexagon nut?
Hexagonal nuts join fasteners with bolts and screws. Hexagonal nuts are widely used, and hexagonal nuts are suitable for machines, equipment or structures with rough surfaces and low precision requirements. Custom hexagonal thick nuts for cleaner, more accurate machines, equipment or structures. The nut thickness is large, hexagonal thickness, usually used for disassembly and assembly. Hexagonal thin nuts have a thin thickness and are mainly used in cases where the surface space of the connecting parts is limited. A nut cap is an internally threaded fastener used to transmit motion or power to a mechanical part.
