Automotive Shock Absorber Seam Welding Machine

Automobile shock absorber Seam Welding Machine: Dual guarantee of sealing and strength

In the manufacturing of Automotive Shock absorption systems, the sealing performance of shock absorbers directly determines their service life and shock absorption effect. Automotive shock Absorber Seam Welding Machine is a professional welding equipment tailored for such core components. It closely connects the cylinder of the shock absorber with key parts such as the end cover through continuous welds, forming a leak-free sealed structure. At the same time, it ensures that the welds have sufficient strength to withstand high-frequency vibrations and pressure impacts, thus safeguarding the stable operation of the shock absorption system. ​

Compared with other welding equipment, this dedicated seam welding machine demonstrates irreplaceable advantages in the manufacturing of shock absorbers. Although the Friction Welding Machine can achieve high-strength connection, in the circular sealed welding of the shock absorber cylinder barrel and the end cover, it is difficult to form a continuous and uniform weld seam, which cannot meet the sealing requirements. The Spot Welding Machine connects through discrete weld points. There are gaps between the weld points, which cannot prevent the leakage of shock-absorbing oil and is simply not suitable for the sealing welding of shock absorbers. The Butt Welding Machine is mainly used for the butt welding of rods, and its welding method is not suitable for the curved surface sealing connection between the shock absorber end cover and the cylinder barrel. Although the Laser Welding Machine for Steel Ring can achieve high-precision welding, the annular structure of the steel ring is quite different from the irregular sealing surface of the shock absorber, and the equipment cost is too high, which is not conducive to mass production. Stud Welding Machine is only used for the fixation of studs and has nothing to do with the sealing welding requirements of shock absorbers. ​

However, the ordinary Seam Welding Machine lacks customized design for the material and structure of shock absorbers. The control of parameters such as welding pressure and current density is not precise enough, and the phenomenon of overburning or false welding of the weld seam is prone to occur. The Automotive Shock Absorber Seam Welding Machine precisely controls the heat input during the welding process through an intelligent parameter adjustment system, ensuring that the weld seam has both excellent sealing performance and sufficient strength to resist the alternating load during the operation of the shock Absorber. Its continuous welding feature perfectly covers the sealing surface of the shock absorber, effectively preventing the leakage of shock absorber oil and significantly extending the service life of the shock absorber. It has become an indispensable key equipment in the manufacturing process of automotive shock absorbers. ​
