Welding automation

With laser cladding, the component surface is melted by a laser beam and joined to form a new, pore-free layer by the addition of a powdered filler material. Prior to laser processing, the components are scanned with a scanCONTROL laser scanner…

In fully automatic welding units, welding head positioning is crucial for the quality of the welded joint. In order to position the welding head at the correct distance, optoNCDT 1900 laser sensors are used. These measure the distance from the…

The position of the welding head relative to the welded seam is a decisive factor in the quality of automated welding processes. Even minor deviations affect the welding result and may cause the need for manual rework or rejection of the…

Automated robotic welding cells monitor the quality of pipes with longitudinal welding on the basis of several points. On the one hand, the edge position must be known along the sheet edge length while also ensuring the optimal alignment of the…

In automatic welding machines, eddy current sensors from Micro-Epsilon ensure high quality welded joints while measuring the travel of the electrodes. The non-contact displacement sensors detect the axial displacement which is influenced by…

When welding components, the weld seam is automatically inspected for quality assurance purposes. The inspection is performed using CFO100 color sensors which detect the weld seam while the component is being rotated. As the weld seam has a…

Brass strips are joined based on the spot welding method. CFO color sensors are used to automatically recognize the weld spots prior to further processing. The multi-teach function allows for the color shades of the shiny weld spots to be…

With additive manufacturing methods such as selective metal melting, the focal point control of the laser is crucial for the process speed and the quality. In order to determine the distance between the print head and the powder surface and to…

The documentation of welding parameters such as cooling time is achieved using high performance pyrometers from Micro-Epsilon. These short-wave temperature sensors enable non-contact temperature measurements of metallic surfaces. The pyrometers…

Optical micrometers from Micro-Epsilon are used to monitor the thickness of welding wires. In this respect, the X-Frame measuring system enables continuous diameter inspections. The X-Frames includes two laser micrometers that detect the wire…

Rigid and video endoscopes are used for the inspection of weld seams in difficult-to-access places. This visual inspection can be performed before, during and after the welding process depending on the respective task. Micro-Epsilon Eltrotec…

Inrotech A/S in Denmark relies on sensors from Micro-Epsilon to achieve optimal quality of weld seams in a fully automatic process. The company has developed a welding robot called "Inrotech-Crawler" which calculates welding processes in advance…

For the maintenance of pipelines, the inspection of the outer weld seam is a decisive criterion. For this purpose, the profiles of the welds seams are inspected in a test station. In order to automate the inspection process, the test facility is…

scanCONTROL laser scanners are used for repair welding of large parts in order to determine the welding track and the robot path. First, the surface of the defective area is scanned by a laser scanner, which is guided over the surface by a robot.…
