Square weld nuts

Welding nut is a kind of nut which is suitable for welding outside the nut. It is usually made of weldable material and is thicker and weldable. Welding is equivalent to turning two separators into a whole. The metal is melted at high temperature and mixed together to cool down. The alloy will be added in the middle. The internal part is the function of molecular force. The strength of the nut is generally greater than that of the parent. 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 pre-welding treatment, ash removal, oil stains and so on.
