Sensors for the Welding Area

Thanks to their particularly robust housing design, the sensors for the welding area are insensitive to high temperatures, flying sparks and welding spatter. This makes them particularly suitable for use in harsh industrial areas such as the automotive industry or machine tool construction.

Long-Range Laser Distance Sensors P2PY




 
  • Durable housing made of stainless steel 316L (1.4404/V4A) – also for welding spatter and flying sparks 
  • High mechanical stability and resistance against shocks and impacts
  • Replaceable PMMA lens with special coating for increased protection
  • Optional replaceable lens made of CR-39 for increased welding field resistance

Long-range laser distance sensors with wintec are high-performance transit time sensors that work with red laser. As a result, they cover large working ranges and reliably detect objects even at great distances. 

The latest wintec generation with DS technology delivers precise results up to 10 meters and sets itself apart in particular by the fact that it reliably detects objects regardless of their color or surface condition, such as gloss – even in extreme inclined positions.

Position Monitoring of Car Body Parts

In automotive shell construction, body parts such as doors, tailgates or fenders are welded by robots. The sensors in the robust stainless steel 316L housing and coated lens check the exact position of the components in the welding device and are resistant to welding spatter or sparks.

Inductive Sensors

Welding Field Resistant Inductive Sensors with Correction Factor 1




 
  • Welding field resistant thanks to Teflon coating (sleeve, sensor cap, nuts)
  • Robust against magnetic direct and alternating fields up to min. 200 mT
  • Very high switching frequencies up to 4,200 Hz
  • High switching distances of up to 50 mm with correction factor 1
Tutorials icon white

Inductive sensors detect metal objects contactlessly through electromagnetic induction. Sensors with correction factor 1 have an identical switching distance on different metals and thus enable precise detection of varying materials.

The welding field resistant sensors are available in different formats and with different detection ranges; installation is flush or non-flush depending on the application area.

2D/3D Profile Sensors

2D/3D Profile Sensors MLZL



 
  • Compact, resistant metal housing – resistant to heat and flying sparks 
  • High-end appearance for high profile quality
  • Powerful lasers (red, blue) in laser classes 2M, 3R and 3B
  • Integrated air flushing and cooling
  • Exchangeable protective screens
Further information on the MLZL design of the weCat3D series can be found here.
2D/3D profile sensors from the weCat3D series use the principle of laser triangulation to create 2D height profiles and 3D point clouds. 
The slim MLZL design is specially developed for optical weld seam tracking and can be attached directly to the robot arm. During the ongoing process, the 2D/3D profile sensor detects all types of joint and can be quickly and easily integrated into the robot controls thanks to suitable robot interfaces.

You can find further information on optical weld seam tracking here.

The MLZL Seam Tracking Sensor in Use – Robust and Precise

Welding Seam Tracking in Robot Cells by 2D/3D Profile Sensors

In fully automatic robot welding cells, it is necessary to determine the exact positioning of the joints on edges, angles or steps before the welding process. For this purpose, a 2D/3D profile sensor is mounted on the robot directly next to the welding torch in the MLZL housing specially developed for weld seam tracking.
