Why a Dedicated Circular Seam Welder for Shock Absorber Tubes
Shock absorber cylinder tubes require a continuous, leak-proof circumferential weld. Any pinhole, incomplete fusion, or inconsistent penetration in the circular seam becomes a failure point under the high-pressure cyclic loading that shock absorbers endure. Manual or generic welding approaches cannot guarantee the seal integrity required for mass production.
This Xinwei horizontal automatic seam welder addresses the problem at the process level. The servo motor drives electrode rotation, which in turn rotates the workpiece via friction. The welding current passes through the electrode-wheel contact point while the part rotates, producing a continuous overlapping seam around the full circumference. The industrial PLC controls every parameter — rotation speed, welding current, electrode force — and the touchscreen HMI allows operators to store and recall recipes for different shock absorber models.
Key Engineering Advantages Over Conventional Seam Welders
1. Servo Motor Drive: Stable Speed, Consistent Weld Overlap
Unlike conventional AC motor drives that exhibit torque ripple at low speeds, the servo motor delivers smooth, precisely regulated rotation with minimal speed fluctuation. This directly translates to uniform weld nugget overlap around the circumference — critical for the gas-tight and liquid-tight seal that shock absorber tubes demand. Welding speed is adjustable from 0.7 to 3.9 m/min to match material thickness and production rate requirements.
2. Industrial PLC with Touchscreen: Recipe Management and Data Traceability
The PLC control system enables full process programming with short cycle times and rapid response. Operators set and modify welding parameters through the touchscreen interface. Real-time welding data and production quantities are displayed and can be exported via USB or uploaded through the MAS (Manufacturing Automation System) interface. This supports quality documentation requirements common in automotive Tier-1 and Tier-2 supplier audits.
3. Customised Fixtures for Different Tube Diameters and Lengths
The machine features a cyclic transplanting mechanism with adaptable fixturing that accommodates workpieces of varying diameters and lengths. When production shifts between shock absorber models, the fixture adjustment is straightforward. For high-volume dedicated lines, custom fixtures can be engineered to enable fully automatic loading and unloading, further reducing cycle time.
4. Built-in Fault Diagnosis: Reduced Downtime and Maintenance Cost
The control system includes comprehensive fault diagnosis functionality. When an anomaly is detected, the system identifies the fault location and displays it on the HMI, enabling maintenance personnel to address issues quickly without lengthy troubleshooting. All supporting control components undergo strict incoming quality control, ensuring stable long-term performance.

Application Scenarios
● Automotive Shock Absorber Production Lines
The primary application is welding galvanized steel shock absorber cylinder tube bodies. The horizontal layout, servo-driven rotation, and PLC control deliver the consistent, leak-proof circumferential seam that automotive shock absorber specifications require. Suitable for both OE production and aftermarket manufacturing.
● Piston Cylinder and Pressure Vessel Welding
Beyond shock absorbers, the machine handles any cylindrical component requiring a sealed circumferential weld: hydraulic piston tubes, pneumatic cylinders, filter housings, and small pressure vessels. The adjustable speed range and multi-material capability (SS, CS, Al) support diverse industrial part portfolios.
● Tier-1 and Tier-2 Automotive Supplier Integration
The PLC data export capability (USB and MAS interface) supports the quality documentation and process traceability requirements common in automotive supply chain audits. Weld parameter logs, production counts, and fault history can be retrieved for PPAP and ongoing process capability reporting.

Frequently Asked Questions
Q: How does the electrode rotation drive the workpiece?
A: The servo motor rotates the electrode wheel. The electrode contacts the workpiece surface, and the friction between the electrode and workpiece drives the tube to rotate. This indirect drive method ensures smooth rotation without adding a separate workpiece spindle, and the welding current passes through the same electrode-workpiece contact point.
Q: Can the machine handle both galvanized and non-coated steel tubes?
A: Yes. The machine welds carbon steel, stainless steel, and aluminium. For galvanized steel specifically, the seam welding process is well-suited because the continuous overlapping weld nuggets maintain seal integrity even with the zinc coating. Welding parameters are adjusted through the PLC touchscreen for each material type.
Q: What KVA rating should I choose for my application?
A: The 80KVA model handles up to 1.2+1.2mm, the 100KVA up to 1.5+1.5mm, and the 160KVA up to 2.0+2.0mm (mild steel). Our engineering team can recommend the appropriate rating based on your tube material, wall thickness, and desired welding speed. Send your specifications for a model recommendation.
Q: Can welding data be exported for quality documentation?
A: Yes. The PLC system supports data export via USB drive and upload through the MAS interface. Real-time welding parameters, production quantities, and fault logs can be retrieved for PPAP documentation, process capability studies, and customer quality audits.
