Understanding the different types of welding fixtures and positioners is crucial to optimize the performance of your robotic welding system. The choice depends on the complexity of the workpieces, the precision required, the volume of production, and the level of automation needed in your operations.
Let’s delve into the specifics of each type to help you make an informed decision.
Layout templates/jigs are simple, cost-effective solutions where the operator manually places and secures the workpiece in the fixture. They are typically used for simple weldments and low-volume production where high precision may not be a priority. However, these fixtures may not be suitable for complex weldments or high-volume production due to the potential for human error and slower processing times.
Semi-automatic fixtures are a step up from manual fixtures. These fixtures often include some level of automation to accurately position the workpiece. They can include features such as pneumatic clamps and automated sliders to speed up the process and reduce the scope for manual error, making them ideal for medium-volume production.
Fully automatic fixtures are designed for high-volume production where efficiency and precision are paramount. These fixtures automatically position and secure the workpiece, eliminating the need for manual intervention. They integrate seamlessly with the robot and often include sensors to verify correct positioning before welding begins.
Single-axis positioners manipulate the workpiece around one rotational axis. They are ideal for workpieces that require welds in a circular pattern or along a curved path. By rotating the workpiece, these positioners ensure the welding robot always has optimal access to the weld joint.
Multi-axis positioners offer more complex manipulation of the workpiece, rotating and tilting along two or more axes. This ability allows them to optimally position even the most intricate workpieces for the robot to weld. They are best suited for complex weldments requiring welds at multiple angles and positions.
