Weld nut is made of weldable material, it is equivalent to the two separate parts into a whole, with high temperature melting metal mixed together and then cooling, alloy will be added in the middle, the internal is the effect of molecular force, strength is generally larger than the matrix strength. Welding nut strength is relatively large, and the use is wide range but due to high temperature will lead to the deformation of the connected parts, and can not be removed, and some active metal can not be used in the usual method of welding, such as aluminum, magnesium, needing protect gas or argon arc welding, processing technology and accuracy requirements.
