ZS Laser Equipment
In the metal fabrication industry, mass production is both an opportunity and a challenge.
How to improve production efficiency while maintaining high welding precision has become a key concern for many manufacturers.
Traditional manual welding methods can no longer meet the growing demand — they are low in efficiency, inconsistent in quality, and costly in labor, which limits production expansion.
Recently, a domestic manufacturer specializing in metal cages partnered with ZS Laser to upgrade its production line with automated laser cutting and welding systems, achieving a major step toward intelligent manufacturing.
ZS Robotic Fully Automated Welding Machine
Customer Background & Project Overview
The customer is engaged in the long-term production of metal cages and steel frame structures, which involve large quantities of square tube cutting and welding on a daily basis.
Due to the high batch volume and repetitive nature of their products, they needed a solution that ensured both precision and speed — making automation the key to enhancing competitiveness.
To meet this need, ZS Laser provided a complete automation solution, including:
One laser tube cutting machine (already installed and in use)
One robotic laser welding system (currently under commissioning)
These two systems work seamlessly together: square tubes are precisely cut by the laser tube cutting machine and then transferred to the robotic welding workstation for automatic welding — creating a continuous and highly efficient production flow.
Customized Robotic Laser Welding Solution
The core of this project is ZS Laser’s customized robotic laser welding system.
Equipped with a multi-axis robotic arm, the system performs flexible multi-angle welding.
ZS Laser’s engineering team designed and configured the system specifically according to the customer’s product structure and welding process requirements.
In fully automated welding, the fixture design is a critical factor determining accuracy and efficiency.
ZS Laser designed a large custom welding fixture platform to securely position the workpieces.
Once the tubes are placed on the platform, the robotic welder automatically identifies the positions and begins the welding process — achieving true hands-free operation.
ZS Cage Welding Custom Welding Fixtures
The combination of the custom fixture and robotic welding system enables synchronized multi-point welding and quick workpiece positioning, greatly improving throughput and consistency.
Technical Highlights & Engineering Details
ZS Laser’s robotic welding system integrates high-precision motion control with intelligent laser welding technology.
Key technical features include:
Custom Fixture Design – Multi-point clamping mechanism designed according to the tube structure ensures accurate positioning and quick replacement.
High-Precision Laser Welding – The robot follows preset paths for precise, smooth, and strong weld seams.
Stable Fiber Laser Source – Ensures consistent energy output, smooth weld formation, and minimal heat-affected zones.
Intelligent Parameter Control – Precise adjustment of focal position, welding speed, and power to achieve optimal results for different weld areas.
Electrical & Safety Protection – Anti-interference grounding and optical safety designs extend equipment lifespan and ensure operator safety.
Every component and process undergoes rigorous calibration and testing to guarantee long-term precision and stability during continuous operation.
On-Site Commissioning & Testing
Before delivery, the ZS Laser engineering team carried out comprehensive on-site debugging and testing to ensure system reliability and performance.
Testing included:
Calibration of laser focus and welding parameters
Verification of fixture repeatability and positioning accuracy
Real-material welding trials and finished product inspection
ZS engineers also provided operator training, covering daily maintenance, parameter adjustment, and safety procedures — ensuring the customer’s team can independently manage production.
After commissioning, the robotic system can perform continuous automatic welding with minimal human supervision, achieving stable and efficient production.
