THE CLIENT
Our client is a well-established construction company in Romania, founded in 2007, known for delivering end-to-end services—from design and consultancy to full-scale execution. The company has built a strong reputation for quality and efficiency in managing complex construction projects.
With a strong focus on industrial buildings, the client operates both within its own facilities and directly on customer sites, carrying out large-scale welding operations that require high precision, speed, and adaptability.
The company frequently performs welding work for industrial halls, where components are large, heavy, and often difficult to access.
THE CHALLENGE
Several operational challenges were impacting efficiency and consistency:
- ● The need for high-quality, uniform welds, even in elevated or hard-to-reach areas
- Manual welding performed both on-site and in the workshop, which was time-consuming and prone to variability
- Operator fatigue and safety risks, especially during repetitive tasks or welding at height
- Limited flexibility when adapting welding processes to different project locations and structural configurations
The challenge was clear: how to maintain consistent welding quality and efficiency across multiple locations without increasing complexity or safety risks.
THE SOLUTION
To gain better control over welding operations—both in-house and on-site—Robot Industries implemented the ZU 3 collaborative welding robot. This compact, mobile, and highly flexible solution was designed specifically for real-world construction environments.
The system was selected for its ability to combine precision welding, mobility, and fast integration in a single solution.
WHY THE ZU 3 COBOT?
- A 6-axis robotic arm enabling multi-directional movement and precise articulation for smooth, controlled weld paths—even on complex structural elements
- A working radius of 626 mm, offering sufficient reach for large components while maintaining a compact footprint suitable for tight or modular spaces
- A payload capacity of 3 kg, supporting various welding torches and lightweight tools for diverse project requirements
- Instant mounting on any metal surface—vertical, horizontal, or angled—without fixed installations, frames, or mounting systems, making it ideal for mobile and at-height welding tasks
Thanks to its portability and plug-and-play setup, the ZU 3 robot became a flexible asset, easily relocated between the fabrication facility and active construction sites.
THE RESULTS
The integration of the ZU 3 collaborative welding robot delivered immediate and measurable improvements:
- Improved welding precision and consistency: Automated motion ensured uniform force, positioning, and timing, eliminating variations caused by fatigue and manual adjustments. Weld quality met both structural and aesthetic standards.
- Reduced execution time and faster project delivery: Standardized welding cycles significantly shortened repetitive and long weld operations, accelerating completion times on large components.
- Maximum flexibility across job sites: The magnetic base allowed rapid deployment on flat, angled, or vertical metal surfaces, both in the workshop and on-site, with minimal setup time.
- Enhanced operator safety and ergonomics: The robot handled physically demanding and high-risk welding tasks, particularly at height or in awkward positions, reducing strain and improving overall safety.
- Greater focus on high-value work: With repetitive welding automated, operators could concentrate on supervision, quality control, and other skilled tasks, improving productivity and job satisfaction.
For Mavitex, the ZU 3 collaborative welding robot became more than a tool—it became part of the team. By introducing mobile automation into their workflow, Mavitex gained speed, flexibility, and operational control, without compromising on safety or weld quality.
This solution shows how collaborative robots aren’t just for factories, they’re ready to support real-world construction sites too.
