What are the commonly used welding methods for Special Tricycle?

Special Tricycle are usually connected by welding, and there are three main welding methods commonly used:

1. Fusion welding: This is a common welding method for Special Tricycle. It mainly uses local heating to heat the joints of the welding parts to a molten state, fuse with each other, and then condense to combine with each other. Arc welding, argon arc welding, and gas welding fall into this category.
2. Brazing (brazing): Similar to fusion welding, Special Tricycle can also be firmly connected. But there are essential differences between the two. Brazing uses low melting point solder and the weldment to be heated together to melt the solder. The molten solder flows into the gaps on the connection surface of the weldment and combines with the solid metal to be welded. , forming a connection after condensation. The weldment itself does not melt during brazing, such as soldering, brazing, etc.
3. Pressure welding: When welding a Special Tricycle, a certain amount of pressure is applied regardless of whether the weldment is heated or not, so that the two joint surfaces are in close contact and promote the bonding between atoms to obtain a firm connection between the two weldments. . Resistance welding, friction welding, and explosion welding all fall into this category.
