Octagonal Welding Tables for Welding Positioners / Manipulators
The Octagonal Welding Table for Welding Positioners/Manipulators is
a polygonal precision fixturing platform specifically designed for
automated welding applications. Unlike conventional rectangular
welding tables, it features an octagonal tabletop structure,
adapting to the rotational requirements of welding positioners and
the multi-directional processing needs of welding manipulators.

Material and Surface Treatment
Main Material:
Standard configuration: Q355 high-strength carbon steel - High
tensile strength and strong load-bearing capacity, suitable for
welding heavy workpieces, offering excellent cost-effectiveness.
High-end version: QT600 ductile cast iron - Excellent shock
absorption, reducing the impact of vibration on positioning
accuracy during rotational operations, suitable for automated
welding of precision parts.
Surface Strengthening Process: Vacuum nitriding treatment + anti-rust and wear-resistant coating.
The surface hardness reaches HRC55-60, capable of withstanding high
temperatures from welding spatter and metal friction, preventing
surface rust and hole wear. The service life is 3-5 times longer
than that of ordinary carbon steel tables.

Core Advantages
- High Adaptability for Automation: Designed specifically for positioners/manipulators with
standardized flange interface compatible with most equipment
brands, enabling quick integration into automated welding
production lines
- Welding Without Blind Spots: Octagonal design with 8 working surfaces provides
multi-directional operating space combined with positioner rotation
for complete weld accessibility
- High-Precision Positioning: Hole system tolerance of ±0.05mm ensures high repeatability with
weld pass rates exceeding 99%
- Flexible Production: Modular tooling adapts to various workpiece shapes and sizes,
reducing changeover time from 1-2 days to 1-2 hours
- Outstanding Durability: Nitrided work surface provides wear and corrosion resistance for
high-frequency automated welding operations
Typical Application Scenarios
- Construction machinery: Automated welding of large structural
components such as excavator boom arms and loader buckets
- Pressure vessels: Rotary welding of annular workpieces such as
storage tanks and pipe flanges
- Automotive manufacturing: Robotic welding production lines for
components such as vehicle frames and rear axles
- Steel structure processing: Multi-angle precision welding of
irregularly shaped steel structural components
After-Sales Service Commitment
