A client from Algiers needed to introduce more flexible automated welding equipment for their structural component production line to enhance welding efficiency and consistency across metal components of varying sizes. Addressing the client’s specific production needs, UMW designed a mobile collaborative robot welding solution. This system integrates a six-axis collaborative robot, a welding system, and a mobile platform, allowing it to move flexibly based on workpiece positioning and perform automated welding from multiple angles.
Client Background
The client specializes in the manufacturing of metal structural components and related industrial parts; daily operations involve welding steel structural components of various specifications.
As order volumes increased, traditional manual welding began to present several issues:
- Inconsistent welding quality among different welders;
- High physical demands on operators due to prolonged, continuous welding;
- The need for frequent repositioning of large structural components;
- Inability of fixed robots to cover multiple, dispersed welding stations;
- A desire to gradually increase automation while maintaining production flexibility.
Consequently, the client sought a solution that would enable automated welding of structural components without requiring the construction of large, fixed robotic workstations.
Key Welding Challenges Faced by the Client
Non-uniform component sizes and shapes
The structural components vary in volume, weld seam length, and weld location rather than following a standardized, single-type design. Therefore, the welding equipment must offer high programmability and adaptability to handle different products instead of repeatedly processing only one product type.
Dispersed welding locations
Some structural components are too large to be easily transported to a fixed welding robot station.
Using traditional fixed robots would require additional tooling, material handling equipment, and safety fencing, which not only consumes significant production floor space but also increases the project’s overall investment cost.
Balancing automation with production flexibility
The client is not simply pursuing high-speed mass welding; rather, they need a robotic system capable of adapting to the production of a wide variety of structural components.
Therefore, Account Manager Leo recommended a solution that enables automated welding of structural components without the need for large, fixed robotic workstations.
UMW Mobile Collaborative Robot Welding Solution
To address the client’s specific situation, UMW proposed a mobile six-axis collaborative robot welding system.
The system comprises a collaborative robot, a welding control system, and a mobile platform, allowing it to be moved to different workstations based on actual production tasks. Compared to traditional fixed robotic workstations, this solution is better suited for multi-station and semi-automated welding production of large structural components.
Mobile Structure
The robot and associated welding equipment are integrated onto a mobile platform, allowing the work area to be adjusted based on the workpiece’s position and reducing the need for frequent handling of large structural components.
6-Axis Flexible Movement
The 6-axis collaborative robot can approach weld seams from various angles, making it suitable for linear welds, fillet welds, and welding at different locations on the structural component.
Flexible Programming
Robot motion trajectories and welding paths can be reconfigured for different products, making the system ideal for producing structural components of various specifications.
Automated Welding
The robot performs welding along preset paths, helping to minimize variations caused by manual operation and improving consistency across similar welds.
Suitable for Multi-Station Use
A single mobile robotic system can serve different workstations based on production schedules, thereby increasing equipment utilization rates.
Why Choose a Mobile Collaborative Robot?
For manufacturers of structural components, traditional fixed industrial robots are not always suitable for every production environment.
Mobile collaborative robots often offer a more flexible automation approach when dealing with large workpieces, frequent product changes, or multiple welding stations. In this project, the mobile platform allows the robot to approach the workpiece, eliminating the need to transport large structural components to a fixed workstation.
This model is particularly well-suited for:
- Steel structural components;
- Metal racks;
- Machinery frames;
- Industrial supports;
- Metal frameworks;
- Medium-to-large welded assemblies;
- High-mix, low-volume metal structural components.
Customer Feedback
After the equipment solution was confirmed, the customer focused primarily on the robot’s actual movement flexibility, welding coverage, and its ability to switch between different structural components.
Through welding tests and solution demonstrations, the customer could clearly observe the entire welding process—including robot positioning, weld path execution, and the quality of the automated welding.
The mobile design also resolved the customer’s previous concerns regarding the limited working range of fixed robots, enabling the unit to move to different welding zones based on actual production tasks.
Ultimately, the customer approved the mobile collaborative robot welding solution and ordered the equipment for structural component production at their factory in Algeria.
What Types of Factories Are Suitable for Mobile Robotic Welding?
Mobile collaborative robots are not suitable for every welding scenario.
For large-scale production lines manufacturing a single product over the long term with very high cycle rates, stationary industrial robot workstations generally offer superior automation efficiency. However, mobile robots offer distinct advantages in the following production environments:
- Workpieces are relatively large;
- Product specifications vary;
- The factory has multiple welding stations;
- Individual order batch sizes are not particularly large;
- There is a desire to reduce investment in large, stationary workstations;
- There is a need to gradually scale up welding automation;
Therefore, when selecting a robotic welding solution, a comprehensive assessment based on workpiece dimensions, weld seam types, production volume, cycle times, and shop floor layout is essential, rather than simply comparing the robots’ technical specifications.
