AWF – autonomous weld following


an extension available for our robotic platforms

One of our research projects is autonomous weld following. This innovative technology is using an industrial camera to recognize the weld seam. Image processing algorithms constantly extract the weld features from the image stream and determine its center position. The information is sent to the on-board motor controllers which maneuver the robot precisely along the weld.


 

OBJECTIVE

Phased Array Ultrasonic is becoming more and more the standard NDT method for weld inspection. Most NDT service companies have trained personnel and modern Ultrasonic equipment to perform these inspections. More than ever asset owners and service companies are under huge pressure in terms of turnover time, quality and safety. With the development of autonomous weld following we are able to support our customers on these inspections. Like the human eye the technology is based on visual recognition of predefinied patterns. It allows the operator to manually drive along the weld or to automize the system by activating on the software algorithms  and motor controlers.

TECHNOLOGY

Depending on the weld and environmental conditions like luminosity, painting or coating the operator can select one of two predefined algorithms to properly detect a weld. One algorithm is template matching where the software compares pre-captured weld templates with the actual camera picture. The second algorithm is SIFT (Scale-invariant feature transform) where the code is looking for specific features which are typical for a weld. Both algorithms need some pictures of the actual weld to work reliably.
