For manufacturers operating in high-mix, low-volume environments, automation often comes with a frustrating trade-off

While traditional industrial robots can improve output in processes such as laser welding, their complexity can also create new bottlenecks through lengthy programming, specialized training requirements, and limited operational flexibility.

For Taiwan-based Fu Zhuan Steel, these challenges became increasingly significant as customer demand shifted toward greater customization, faster lead times, and smaller production batches.

With over three decades of expertise in sheet metal fabrication, Fu Zhuan Steel needed an automation solution that could do more than weld. It needed to simplify operations, reduce dependency on scarce skilled labor, and make robotic welding accessible to more of its workforce.

The Challenge: Complex Automation in a Fast-Changing Market

Before adopting collaborative automation, Fu Zhuan Steel relied on conventional industrial robots for welding tasks. While technically capable, these systems required advanced programming knowledge and extensive employee training, often taking more than a month before operators could work independently.

This created several operational barriers:

• Only a small number of employees could operate robotic systems
• Scaling production was difficult due to labor shortages
• Frequent design changes slowed down production adjustments
• Traditional apprenticeship models became harder to sustain

In a market increasingly defined by agility, this approach limited responsiveness.

The Solution: SmoothTool + UR12e

By combining the UR12e with SmoothTool from Smooth Robotics, Fu Zhuan Steel transformed its laser welding workflow.

SmoothTool enabled operators to program welding paths quickly and intuitively, eliminating the need for advanced coding skills. Together with the UR12e’s hand-guiding capabilities, this significantly reduced complexity and dramatically shortened onboarding time.

Key outcomes:

• Training time reduced from over one month to just 1–2 days
• Faster setup for new welding jobs
• Greater flexibility for high-mix, low-volume production
• Lower dependency on experienced robot programmers
• Improved production scalability despite labor shortages

Empowering Operators, Not Just Automation

At Smooth Robotics, our mission is to make robotic welding practical and accessible for real-world manufacturers, especially those navigating workforce shortages and production variability.

For Fu Zhuan Steel, SmoothTool helped bridge the gap between advanced automation and everyday usability, enabling more employees to operate welding systems confidently and productively.

“In the past, training operators to run a conventional industrial robot often took more than a month. With the UR12e cobot, training can be completed in just one to two days. That not only fills labor gaps quickly, but also makes the high-mix, low-volume production far more efficient!”
— Yi-Chun Chang, Special Assistant to the General Manager, Fu Zhuan Steel

In welding operations, even small errors can quickly become expensive. Rework, scrap metal, and wasted consumables all add up. This is where collaborative robots (cobots) can make a tangible difference.

Solutions such as SmoothTool, the cobot welding software developed by Smooth Robotics, further support this process by making it easier for operators to program precise and repeatable weld paths. The software simplifies complex welding programming and helps teams maintain consistent weld quality, reducing the risk of errors that lead to scrap and rework.

Reducing waste where it matters most

One of the biggest challenges in welding is maintaining consistent quality over long production runs. Human welders bring valuable expertise, but fatigue, repetitive work, and complex weld paths can lead to variation and errors. 

Collaborative robots help address this challenge by delivering high precision and repeatability. Once programmed, a cobot can execute the same weld path consistently, reducing the likelihood of defects that lead to scrap metal or costly rework.

For manufacturers, this translates into a direct operational benefit:

• Less wasted material 
• Fewer rejected parts 
• Lower costs related to rework and consumables 

According to insights shared by Universal Robots, reducing material waste through precision and repeatability is one of the key ways cobots support more efficient manufacturing processes.

Improving Welding Operations 

Robotic welding has long been associated with improved production efficiency. With cobots, this capability becomes more accessible, particularly for small and medium-sized manufacturers.

By automating repetitive welding tasks, cobots help stabilize production output and maintain consistent quality across batches. A A recent academic research in MDPI Sustainability Academic on robotic welding stations also shows that optimized robot programming and motion paths can significantly improve process efficiency while reducing unnecessary rework and material waste.

Instead of replacing welders, cobots typically take over the most repetitive and physically demanding tasks, allowing skilled operators to focus on programming, quality control, and supervision.

Tools like SmoothTool enable welders to quickly generate advanced welding paths through an intuitive interface, without requiring deep robot programming expertise. This approach allows manufacturers to automate repetitive welds faster while maintaining high precision and productivity.

A practical approach to Sustainability 

In many cases, sustainability in manufacturing does not come from a single breakthrough technology. Instead, it comes from incremental improvements that reduce waste and improve efficiency across the production process.

In welding operations, collaborative robots contribute to this progress by helping manufacturers: 

• Reduce scrap metal and material waste 
• Minimize costly rework 
• Improve process consistency
• Support safer and more sustainable working conditions for welders 

By focusing on waste reduction and operational efficiency, cobots demonstrate how sustainability can move from an abstract concept to a practical advantage on the shop floor.
