Temperature Sensors:Temperature sensors are among the most commonly used sensors in welding automation.They measure temperature changes during the welding process and allow for real-time adjustments based on requirements.Temperature sensors come in various types,including thermocouples,resistance temperature detectors(RTDs),and infrared sensors.These sensors provide accurate temperature data,helping to control welding parameters and prevent overheating or undercooling.
Contact Sensors:Contact sensors are used to detect contact force and displacement during the welding process.They can measure the contact force between the welding gun or wire and the workpiece,ensuring proper welding connections.Contact sensors can also monitor displacement during welding,assisting in adjusting welding position and orientation.Common contact sensors include force sensors,displacement sensors,and pressure sensors.
Laser Displacement Sensors:Laser displacement sensors are commonly used sensors in welding automation.They utilize laser beams to measure displacement and shape changes of the weld seam or workpiece surface during welding.Laser displacement sensors measure the distance variation between the laser beam and the weld seam or workpiece,enabling real-time monitoring of displacement,deformation,and dimensional errors during welding.This helps achieve precise welding position and weld seam control,improving welding quality and consistency.
Vision Sensors:Vision sensors play a crucial role in welding automation.They capture real-time images during the welding process and perform image processing and analysis.Vision sensors can detect welding position,weld seam quality,wire position,and other parameters,assisting in adjusting welding parameters and correcting welding defects.Common vision sensors include cameras,laser sensors,and photoelectric sensors.
Current Sensors:Current sensors are used to measure the magnitude and variations in welding current.The stability of current is vital for welding quality during the welding process.Current sensors can monitor current fluctuations and abnormalities,facilitating timely adjustments of welding parameters to ensure proper welding connections.
The sensors mentioned above are commonly used in welding automation,with each sensor type playing an important role in specific welding applications.By utilizing these sensors,welding automation systems can monitor and control critical parameters in real-time,improving welding quality,efficiency,and safety.With the continuous advancement of technology,sensor functionality and performance are constantly improving,further driving the development of welding automation.
