The collision welding machine is actually a resistance welding machine, and its welding principle is to use the resistance heat and a large amount of plastic deformation energy in the welding area to make the two separated metal atoms close to the lattice distance to form a metal bond, and produce a sufficient amount of common grains on the joint surface to obtain welding points, welds or butt joints. It is a connection method with stable welding quality, high production efficiency, and easy mechanization and automation, widely used in fields such as automotive, aerospace, electronics, and household appliances.

Main application: Used for welding rods, pipes, steel sections, etc. Capable of welding metal with a diameter of up to 16mm and a cross-sectional area of 200mm, suitable for use in various hardware industries, such as bicycles, fans, kitchenware, and other products.

In addition to the general functions of an AC pulse spot welding machine, a collision welding machine also has the following welding characteristics: it can place the workpiece end face relative to each other, use the contact resistance between the two end faces, and generate high temperature and heat at the joint, and achieve fusion under pressure. This machine can be equipped with three discharge functions. For medium carbon steel, it has preheating and welding annealing functions, and is specially equipped with parallel linear sliding rails to ensure parallel compression of the forging force during welding, which is beneficial for smooth and firm welding joints.
