How a 7-Axis Cobot Improves
Welding Efficiency
Welding automation needs precision, consistency, and efficiency. This field video demonstrates how a 7-axis cobot enhances torch positioning, allowing for better access in tight spaces and complex geometries. The added flexibility reduces manual adjustments, minimizes downtime, and improves overall weld quality.

Why the 7th Axis Matters
Traditional 6-axis cobots handle many welding applications, but the 7th axis provides key advantages that improve efficiency and quality:
- Better Reach & Angles
- A 7-axis cobot moves like a human arm, reaching weld positions that 6-axis robots struggle with.
- Eliminates the need for workpiece repositioning, reducing cycle time.
- Less Fixturing & Setup
- With greater flexibility, the cobot adjusts dynamically to the weld joint.
- Reduces the need for complex fixtures and streamlines setup time.
- More Efficient Welding
- Handles linear, circular, stitch, and pattern welds with smoother transitions.
- Ensures consistent bead placement and reduces defects.
- Faster Programming
- The extended range of motion allows for fewer manual adjustments.
- Enables easier automation of high-mix, low-volume production runs.
