The weld nut is a nut that is suitable for welding outside the nut. It is generally made of weldable material and is thick and suitable for welding. Welding is equivalent to the two separate pieces as a whole, and the metal is melted at a high temperature and mixed. When cooled together again, the alloy will be added in the middle, and the inside is the effect of molecular force, and the strength is generally greater than the strength of the mother. The welding parameters of the experiment depends on the weld fusion size, adjust the welding parameters according to the fusion size, until the elimination of defects. Of course, the quality of welding is related to the pre-weld treatment, cleaning, grease, etc.
Weld nut
During the welding process, the workpiece and the solder melt to form a molten zone, and the molten pool solidifies and then forms the connection between the materials. In this process, it is usually necessary to apply pressure. There are many sources of welding energy, including gas flames, arcs, lasers, electron beams, friction, and ultrasonics. Until the end of the 19th century, the only welding process was metal forging that had been used by blacksmiths for centuries. The earliest modern welding techniques appeared at the end of the 19th century, first with arc welding and oxygen gas welding, and later with resistance welding. In the early 20th century, with the start of the First and Second World Wars, the need for inexpensive, reliable connection methods for military equipment was enormous, thus promoting the development of welding technology. Today, with the wide application of welding robots in industrial applications, researchers are still deeply studying the nature of welding and continue to develop new welding methods to further improve the welding quality.
The production process is the material of the workpiece being welded (same or different), heated or pressurized or both, and with or without filler material, the material of the workpiece is built up between atoms to form a permanent connection process , Welded nuts are fasteners with internal threads that are used with bolts. Has internal threads and is used with a screw to transmit mechanical or mechanical parts.

Advantages and disadvantages of welding, strength is relatively large, and the use of a wide range, thin and thick can be, but due to high temperature can lead to deformation of the connector, and can not be disassembled, and some live metal can not be welded by the usual methods, such as aluminum, magnesium, etc., need protective gas Or argon arc welding, require processing technology and precision
