Motorized Turn Tables are used to produce high quality welds in a variety of different applications. They are typically used to rotate a part accurately about it’s centerline. They can also be used to rotate parts for fit-up applications and pre/post weld heating processes. You can perform various types of welds in a multitude of positions. Welding is performed using GTAW, PAW, GMAW, FCAW, SAW or YAG Laser.
Benefits: The AMET Turn Tables have several benefits over welding the part manually or by using just a motorized carriage or “orbital” approach, including:
- Able to rotate the part continuously without having to worry about entangling cables and hoses.
- Able to rotate the part accurately and consistently.
- Secure weld ground point.
- Gas back purge capability.
- Add tooling to support part and/or weld joint.
- Increased weld (arc-on) time.
- No need to assemble track around part.

Capacities:
AMET currently produces motorized turn tables with weight capacities from 250 to 60,000 kg (550 to 132,500 lbs). All turn tables have the following general capacities and specifications:
- Rotational Speed Accuracy: +/- 2% of base speed or +/- 1% on precision models.
- Spindle Accuracy: 0.1 mm TIR (.005”).
- Rotational Backlash less then 20 arc minutes on Standard, less than 5 arc minutes on precision.
- AC Motor with AC Vector Drive control on standard units, upgraded to Servo Drive on precision units.
- Speed Range Ratio of 40 to 1 on standard units, 200:1 on precision units.
