Description
I.Hydaulic cylinder welding machine Product overview
Hydraulic cylinder seam welding machine is an automatic welding solution developed for hydraulic cylinder manufacturers.
It is mainly used for circumferential seam welding between cylinder tubes, cylinder heads, flange parts and other circular components.
The machine can be equipped with TIG welding, MIG welding or MAG welding systems according to different material requirements.
II.Hydraulic cylinder welding mahcine Features
1. Automatic Circumferential Welding System
The equipment adopts automatic rotation and welding control technology.
During operation, the workpiece rotates at a stable speed while the welding torch maintains accurate positioning, ensuring uniform welding seams.
2. Precision Welding Control
The welding speed, rotation speed and welding parameters can be adjusted according to different cylinder diameters and materials.
This improves welding quality and reduces operator dependence.
3. Heavy-duty Machine Structure
The machine adopts a rigid welded steel frame structure.
It provides excellent stability during high-speed rotation welding and ensures long-term operation reliability.
4. Professional Hydraulic Cylinder Welding Fixture
The customized fixture can accurately position hydraulic cylinder components.
It improves welding repeatability and prevents welding deformation.

IV.Hydaulic cylinder welding machine Structure

1.Clamping Mechanism
- Spindle Box: Drives the chuck to rotate using a servo motor and reducer.
- Tailstock: Secures and releases the workpiece using a hydraulic cylinder, while the servo motor drives the tailstock forward and backward. It is also equipped with a positioning cylinder; when it reaches the designated welding position, the positioning pin inserts into the positioning hole, thereby locking the tailstock.


2.The suppoter
The central support is responsible for clamping and fixing the central axis of the cylinder body, ensuring that the workpiece will not run radially or deviate during rotary welding; while the material support with cylinders uses pneumatic lifting function to actively support long or heavy cylinders during loading and unloading, which not only reduces the labor intensity of workers, but also can counteract the sagging deformation of the workpiece by adjusting the support height.


3.Welding Head System
The welding head provides accurate torch positioning and stable welding movement.
It ensures consistent welding penetration and appearance.

4.Preheating Function
The preheating coil is responsible for directly heating the weld area, slowing down the post-weld cooling rate by increasing the temperature of the base material, thereby preventing cracks and hardened structures. The preheating control cabinet monitors and adjusts the heating power in real time through temperature controllers and sensors to ensure that the temperature is accurate and stable within the set range. It also has over-temperature alarm and interlock protection functions with the welding machine.
