Diffuse Mode Sensors Evaluate Welding Caps
Detecting faults including inclusion, faulty dressing, or burrs, Pepperl+Fuchs’ WTS10 diffuse mode sensors provide non-contact evaluation of the quality of welding cap fronts. The devices check upper and lower welding caps simultaneously and present pre-fault (near the limit) indication for proactive maintenance. The units offer a scratch-resistant mineral glass lens, position tolerance of ±2 mm, tilt angle tolerance of ±1.5°, coaxial optics with parallel beam path; and status LEDs indicating for “good,” “pre-fault” and “fault” weld tip status. The sensors demonstrate a consistent detection range from 2 mm to 12 mm, regardless of the length of the welding cap or whether the welding cap is new or a fully-dressed tip.
