Project Introduction: Haifei Servo Energy Storage Spot Welder

Aug 10,2026

Automotive body and safety components are mostly made of high-strength steel, hot-stamped steel and galvanized sheets. Traditional welding machines deliver unstable pressure with limited precision, making cold joints & detachment hard to eliminate fundamentally. Haifei servo energy storage spot welder adopts servo electric cylinder + AI intelligent monitoring system with capacitor instantaneous energy release technology to eliminate cold & loose welds.

I Customer Background & Production Pain Points

The client produces auto body structures, chassis parts and safety supports involving nut & bolt projection welding.

Old process drawbacks:

1.Conventional air cylinder machines generate fluctuating pressure; pressurization speed cannot be programmed, leading uneven stress on projections;

2.Lack of dynamic adjustment function; hidden cold & detached welds frequently occur;

3.No real-time monitoring; incomplete equipment data recording.

II Customer Requirements

1.Adopt servo electric cylinder to realize adjustable welding pressure & displacement curves for higher response & precision;

2.Capacitor energy storage system for controllable instantaneous heat input & narrow heat-affected zone;

3.AI intelligent monitoring with multi-group parameter storage and full data traceability.

III Custom R&D Solutions

The R&D team optimized schemes targeting automotive plate welding challenges:

1.Process Verification: Welding tests on different steel grades & fastener specifications;

2.Equipment Selection: Haifei servo energy storage spot welder delivers smooth, concentrated pressure & energy for stable operation;

3.Structural Design: Stable machining accuracy, less electrode impact abrasion, longer service life. Multi-program storage supports multi-model production;

4.Core Advantages

Stable Pressurization: Uniform pressure, perfect weld forming

Smooth Energy Release: Small heat-affected zone, fits high-strength steel

Intelligent Control: Real-time monitoring & full traceability

IV Delivery & After-sales Feedback

Pre-acceptance and inspection finished. Continuous trial runs keep stable qualified rate. All historical defects eliminated after deployment. Clients recognize responsive, professional after-sales service.
