Welding nuts

Welding nut is a nut suitable for welding outside the nut, generally made of weldable material and thicker suitable for welding, welding is equivalent to turning two separate parts into a whole, melting the metal with high temperature and mixing it together and then cooling, the middle will add alloy, the internal is the role of molecular force, the strength is generally greater than the strength 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 defect is eliminated. Of course, the quality of welding is related to pre-welding treatment, ash cleaning, oil stains, etc.

Pros and cons

Welding, the strength is relatively large, and the use range is wide, thin and thick, but due to high temperature will cause the connection to be deformed, and not removable, and some active metals can not be welded by the usual methods, such as aluminum, magnesium, etc., need protective gas or argon arc welding, requiring processing technology and precision
