Welding nut is a kind of nut suitable for welding outside the nut. It is generally made of weldable materials
and is thick and suitable for welding. Welding is equivalent to turning two separate parts into one body. 
The metal is melted at high temperature and mixed After cooling down together, an alloy will be added in
the middle. The internal force is the role of molecular force, and the strength is generally greater than the
strength of the matrix. The experiment of welding parameters depends on the fusion size of the weld, 
and the welding parameters are adjusted according to the fusion size until the defects are eliminated. 
Of course, the quality of welding is related to the pre-welding treatment, such as cleaning, oil stains, etc.

A weld nut is a special type of nut specifically designed to be welded to another object (stud welding). 
There are various types for different applications.

Hex & square nuts

These nuts are very similar to standard square or hex nuts, but have a locating boss and welding projections. The bosses also keep weld spatter out of the threads
