Problem Statement
- Generally, there is a high demand for performing welding without any manual intervention specially during when product shape/size changes.
- The existing methods of making welding process automation plays a vital role in modern manufacturing industries to meet production targets.
- Today’s automotive welding, including industrial robots are smart machines which can be used to perform physical activity along with decision making, however they need to re-programming of fabrication when product shape or size changes, thus making it difficult to work without manual intervention.
- Here, this invention offers an alternative solution to carry out welding of jobs with varying location, size, shape and orientation by using photogrammetry and a self-learning AI algorithm.
Technology
- The principal object of the present patent is to provide a method (refer FIG.1) and an apparatus for self-learning based automated welding.
- Referring to the FIG. 2, in intelligent weld system (18) the CMOS camera (19) is attached to welding torch (11), the camera moves around the work piece and captures images of the work piece.
- An image capturing controller (20) sends the captured images to cloud for image processing.
- The cloud (21) which determine geometric and semantic information of the work piece and marks the weld trajectory in the digital space.
- The identified weld seam will be converted to G code to perform the welding in the physical space.
Key Features/Value Proposition
1.The method effectively identify dimensions and orientation of a work pieces in the workspace from the 3D model using photogrammetry.
2.This method detects weld trajectory on a dimensions and orientation of the work pieces by considering intensity differences of each work pieces using a self-learning algorithm.
3.This method transforms the identified weld trajectory into machine instructions to perform welding in a physical space.
4.The size of the work piece and the weld seam is not limited by the workspace.
5.This method can be used for welding large structures that are bigger than the workspace.
6.This system is designed to use fusion arc welding processes such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), etc.
