The intermediate frequency spot welding machine uses the resistance heat and the amount of plastic deformation energy of the metal itself in the welding zone. The metal atoms between the two separated surfaces are close to the lattice distance to form a metal bond, which generates sufficient eutectic grains on the bonding surface. Get solder joints.
The molten metal is isolated from the air, and the metallurgical process is simple. The heat affected zone is small, the deformation and stress are also small, and it is not corrected and heat treated after welding. No filler metal is needed, and the welding cost is low. The operation is simple, and it is easy to realize mechanization and automation. The production efficiency is high, and there is no noise and harmful gas, and it can be compiled on the assembly line together with other manufacturing processes.
Lack of reliable non-destructive testing methods. The spot welded lap joint increases the weight of the component, and the tensile strength and fatigue strength are both low. Equipment cost is high and maintenance is difficult.
