Non-standard custom shaft is a kind of welding nut. It has a wide range of use, high strength, and can be thin or thick. However, due to high temperature, the connected parts will be deformed and cannot be disassembled, and some active metals cannot be welded by ordinary methods. , such as aluminum, magnesium, etc., require shielding gas or argon arc welding, and require processing technology and precision.

Non-standard custom shaft is a nut suitable for welding outside the nut. It is generally made of weldable materials and is thicker for welding. Welding is equivalent to turning two separate parts into a whole, and using high temperature to weld the metal After melting, they are mixed together and then cooled. The alloy will be added in the middle. 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.

It is a process in which the material of the workpiece to be welded (same or different) is connected by heating or pressure or both, and with or without filler material, so that the material of the workpiece achieves the harmony between atoms and forms a connection. The welding nut is Fasteners with internal threads for use with bolts. A mechanical part with an internal thread and used in conjunction with a screw to transmit motion or power.
