Welding nut is a kind of nut suitable for welding outside the nut. It is generally made of weldable material and is thicker and suitable for welding. Welding is equivalent to turning two separate parts into a whole, melting the metal at high temperature and mixing it. After cooling down together, alloys will be added in the middle, and the interior is the effect of molecular force, and the strength is generally greater than that of the parent body. 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. Welding has high strength and wide range of use. It can be thin or thick. However, due to high temperature, the connected parts will be deformed and cannot be disassembled. Moreover, some active metals cannot be welded by ordinary methods, such as aluminum, magnesium, etc., requiring protective gas or argon. Arc welding requires processing technology and precision.
