The principle of seamless welding is gas-shielded welding, also known as gas-shielded arc welding or gas welding, which uses arc as the heat source and gas as the protective medium. During the welding process, the shielding gas is formed around the arc to form a shielding gas layer, which insulates the arc and water pit, prevents the influence of harmful gases, and ensures the stable burning of the arc. Gas-shielded arc welding is classified by electrode condition, mode of operation, type of shielding gas, power, polarity, and field of application.
seamless welding is performed according to certain conditions. Inert gas welding can be performed using various gases. The most commonly used shielding gases are carbon dioxide, argon, helium, hydrogen and gases. The advantages of gas arc welding are good wire arc, easy centering, easy welding in any position, automatic welding, small welding arc, small weld pool, high welding speed, narrow heat affected zone, small welding position deformation, strong cracking. Tolerance. , good welding quality. The drawback is that it is not suitable for welding in windy conditions and has a strong arc radiation.
Seamless welding technology not only eliminates welds, it also improves accuracy, surface finish and part appearance. At the same time, the seamless welding technology in the injection molding process enables effective control and shortening of the mold making cycle. Products made this way have a better surface finish, so he doesn’t have to plate and anneal twice to avoid dimensional changes due to shrinkage of the two parts.
