Case Study: Improving Welding Strength of Copper-Plated Welding Screws
The customer uses copper-plated welding screws to join workpieces. However, in actual application, the customer has reported insufficient weld strength and inadequate bonding between the stud and the workpiece, leading to a tendency for the screws to detach.
Customer Requirements and Project Expectations
The client has long used copper-plated welding screws to join metal components. They aim to optimize the surface condition of the product to ensure a more robust bond between the welding screw and the workpiece, thereby achieving more stable and reliable welding results.
The customer is concerned not only with the dimensional compatibility of individual rivets but also with whether the entire connection solution can reliably replace the original bolted connection in a real-world assembly environment.
Client Detail Requirements
The client’s key requirements include:
- Improve Welding Connection Strength
The customer requires the welded screw to form a stable connection with the workpiece after installation.
- Ensure Stable Welding Performance
The customer wishes to reduce performance variations between product batches. Welding screws from different production batches all meet the usage requirements.
- Optimize Surface Treatment Process
The customer needs to address the impact of surface treatment variations on welding performance and ensure that the copper plating layer does not interfere with effective bonding during the welding process.
- Reduce Quality Risks During Production
Reduce product rework and assembly issues caused by welding failures by improving fastener performance.
Customer Pain Points
1. Insufficient Welding Strength
Some welded screws fail to achieve the expected welding strength.
2. Poor Welding Contact Between Fastener and Workpiece
Insufficient welding contact area was formed between the screw and the workpiece, resulting in a suboptimal welding bond.
3. Surface Treatment Affecting Welding Performance
An increase in the thickness of the copper plating layer prevents the weld screw from properly bonding with the workpiece, thereby reducing welding performance.

Why Copper-plated welding screws Are Recommended
- Strong Welding Connection
By properly controlling the coating thickness, the weld screw can achieve full contact with the workpiece, thereby enhancing the weld bond strength and reducing the risk of loosening or detachment during use.
- Suitable for Metal Assembly Applications
The welding method is suitable for joining metal sheets, meeting various requirements regarding space, strength, and connection stability.
- Reliable Surface Treatment Control
Surface treatment processes directly affect welding performance. Strict control of the copper plating thickness ensures stable product performance.
