Automatic Valve Core Projection Welding Machine

In the Valve system of automotive engines, the valve Core, as a key component controlling the intake and exhaust of gases, its Welding quality directly affects the airtightness and working efficiency of the engine. The Automatic Valve Core Projection Welding Machine is a professional welding equipment tailor-made for this precise component. It takes advantage of the characteristic of convex points concentrating current to achieve precise welding at the tiny connection points between the valve core and related components. The weld points are small and firm, with an extremely small heat-affected zone, perfectly meeting the strict requirements of the valve core for sealing performance and structural accuracy. ​

Compared with other welding equipment, this automatic projection welding machine demonstrates unique advantages in valve core welding. The Friction Welding Machine achieves connection by generating heat through high-speed friction. However, the impact force during its welding process can easily cause deformation of micro-components such as valve cores and damage their precise structures. The size of the weld points in the Spot Welding Machine is difficult to control precisely. For the tiny welding surface of the valve core, it is easy to have problems such as overly large weld points covering the key functional areas or overly small ones resulting in insufficient connection strength. The Butt Welding Machine is suitable for the butt welding of larger-sized rods, but it is not suitable for the welding of small and structurally complex components such as valve cores. The Seam Welding Machine is mainly used for the welding of continuous sealed weld seams, while the welding requirement of valve cores is point-like precise connection, and the compatibility of the two is extremely low. The Laser Welding Machine for Steel Ring focuses on the annular welding of steel rings, but its optical path design and parameter Settings do not match the micro-welding requirements of valve cores. The Stud Welding Machine is only used for fixing studs to workpieces and cannot complete the precise connection between valve cores and other components. ​

The Automatic Valve Core Projection Welding Machine, in light of the characteristics of the valve core, adopts a micro-convex point design and precise current control technology. It can form high-strength weld points on a very small welding surface while minimizing the impact on the surrounding structure to the greatest extent. Its automated positioning system can ensure that each welding is precisely aligned, avoiding errors caused by manual operation and significantly improving the consistency and pass rate of welding. Whether it is to ensure the airtightness of the engine or to maintain the long-term stable operation of the valve core, this equipment can provide reliable welding support and has become an indispensable key device in the valve core manufacturing process. ​
