Welding is equivalent to turning two separate parts into a whole. The metal is melted at high temperature and 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 higher than that of the parent body. Pressure riveting nuts are generally used for The thin-walled plate is embedded by pressure, and the contact surface is the contact stress, that is to say, the strength depends on the connector and the parent body. Insufficient strength will cause plastic crushing and deformation failure. These two types have their own advantages and disadvantages, such as welding, which has relatively high strength and a wide range of applications. Both thin and thick can be used, but due to high temperature, the connected parts will be deformed and cannot be disassembled, and some are active. Metals cannot be welded by common methods, such as aluminum, magnesium, etc., shielding gas or argon arc welding is required, and processing technology and precision are required, while the rivet nut is simple to install, can be disassembled, easy to install and transport, etc., and is suitable for almost any punchable. Metal, but has a narrow range of use and can only be used for thin-walled or sheet metal connections.

1. Difference: The pressure riveting nut is generally used for thin-walled plates. It is embedded by pressure. The contact surface is the contact stress, that is to say, the strength depends on the connector and the parent body. The nut is subjected to shear stress, so if the nut is Insufficient strength will cause shear failure, and insufficient strength of the parent body will cause plastic collapse deformation failure. Welding is equivalent to turning two separate parts into a whole. The metal is melted at high temperature and mixed together and then cooled. An alloy is added in the middle. The interior is the effect of molecular force, and the strength is generally greater than that of the parent body.

2. These two types have their own advantages and disadvantages, such as welding, which has relatively high strength and a wide range of use, both thin and thick, but due to high temperature, the connected parts will be deformed and cannot be disassembled, and some active metals cannot be welded by ordinary methods. For example, aluminum, magnesium, etc., require shielding gas or argon arc welding, and require processing technology and precision. The rivet nut is simple to install, can be disassembled, easy to install and transport, etc. It is suitable for almost any metal that can be punched, but it has a narrow range of use and can only be used for thin-walled or sheet metal connections.

Relatively speaking, the copper rivet nuts is easier to meet the current lightweight requirements. Welding has great restrictions on the connection between different alloy materials. Different alloys have different melting points, which makes welding very difficult.
