Custom Welding Equipment ▪ Automotive Manufacturing | Specialized Dual-Sided Welding Machine for Automotive Shock Absorber Brackets — Patented Technology Enabling High-Efficiency Mass Production

PDKJ Shock Absorber Steering Bracket Welding Machine

▷ Application Industry: Automotive Manufacturing
▷ Workpiece: 3+3 mm carbon steel shock absorber steering bracket U-clamp

This Issue Highlights:

PDKJ’s shock absorber steering bracket welding machine is specifically designed for double-sided projection welding of automotive shock absorber U-clamps. It has been successfully delivered and put into mass production, enabling efficient and stable automated manufacturing while supporting capacity expansion and process upgrades.

1. Project Background

Client Profile:
A large domestic automotive manufacturing group specializing in complete vehicles and core component R&D and production, with extremely high requirements for welding strength, dimensional accuracy, and consistency.

Project Origin:
With the rapid growth of new energy vehicle sales and capacity expansion, the client’s Xi’an production base urgently required an upgrade to its welding process for shock absorber steering brackets.

Existing Challenges:
The original equipment suffered from slow cycle times and changeovers, unstable welding strength, excessive spatter, and poor dimensional consistency—making it unable to meet the demands of high-volume, high-standard mass production.

2. Production Pain Points & Core Requirements

Three major challenges in the client’s production:

• Efficiency bottleneck: Long welding cycle per workpiece, unable to match expansion pace

• Quality fluctuation: Incomplete nugget formation, spatter, over-welding, and large gaps between parts

• High strength requirement: Welding strength must consistently exceed 20 kN to meet vehicle safety standards

Core Requirement:
A dedicated projection welding system capable of automated loading, welding, and unloading, with fast cycle times and one-click switching between multiple vehicle models and welding specifications.

3. Key Advantages of PDKJ Welding Machine

To address slow cycle times and poor consistency in mass production, PDKJ developed a customized welding solution with the following advantages:

1. Double-Sided One-Time Welding for High Efficiency

Designed specifically for double-sided projection welding of steering brackets and U-clamps. Both sides are welded in a single loading process, eliminating flipping and repositioning.
Cycle time is stabilized at 16 seconds per part, supporting continuous 12-hour operation and meeting expansion needs.

2. Multi-Product Compatibility with Fast Changeover

One set of tooling supports multiple product specifications. Tooling changeover takes only 15 minutes, with no complex adjustments required—significantly reducing downtime and improving equipment utilization.

3. Reliable Welding Strength & High Consistency

Utilizing medium-frequency inverter DC welding technology, the system ensures stable current output and concentrated heat input.
Welding strength reaches ≥20 kN, with full nugget formation, no gaps, no spatter, and no over-welding. Product dimensions and appearance remain consistent, meeting automotive-grade quality standards.

4. Intelligent Full-Process Control

The system can store 16+ sets of welding parameters, enabling one-click switching between models and processes.
Supports full-process control including pre-pressing, welding, tempering, and smooth current ramp-up/down.
Equipped with dual-hand start, safety light curtain, fault self-diagnosis, and current anomaly alarms for safe and easy operation.

5. Smart Cooling System for Longer Service Life

Features grouped parallel water cooling with triple monitoring of water pressure, temperature, and flow rate, along with anti-leak back-suction design.
Effectively dissipates heat and protects electrodes and transformers, reducing wear and maintenance costs.

4. Patented Technology & R&D Strength

The delivered welding system is built on PDKJ’s independently developed core technology and has been awarded the invention patent:
“A Double-Sided Welding Machine for Automotive Shock Absorber Steering Brackets.”

Both the core welding process and equipment structure are protected by independent intellectual property rights.

From equipment R&D and manufacturing to factory testing, on-site installation, after-sales service, and technical training, PDKJ provides a one-stop closed-loop service. With patented technology, reliable equipment quality, and attentive service, PDKJ has earned the trust of its partners.

5. Delivery Results: Stable Production Creates Value

After commissioning, the system achieved:

• [Quality Compliance] Welding strength consistently >20 kN, eliminating strength fluctuations

• [Quality Improvement] Significant improvement in weld consistency and yield rate

• [Capacity Matching] Stable cycle time fully supports mass production demands

• [Cost Control] Stable operation with greatly reduced maintenance costs

Final Outcome:
A complete balance of quality, efficiency, and stability, providing strong support for the client’s production upgrade.
