Please provide a short description of the state-of-the-art and/or current trends in the field? How does the result fit into it?

To assure or even to improve quality in welding automation is a topic for extensive research and development since many years.

When a weld is manually performed by a welder, this one takes appropriate actions by lifting or lowering the welding torch, or executing suitable swinging movements or again speeding up or fasting down the welding speed in accordance to the local condition of the joint to fill. In such a manner the molten metal deposition results smooth and regular compensating any irregularity of the joint.

Even if several automated or robotized solutions exist, they are not able to take into account the disturbance variables before mentioned.





What is the problem/need/knowledge gap that the research result is responding to?  How was it addressed before?

Attempts to improve intelligence in order identify irregularity in the welding process behaviour online and to respond proactively are currently one of the emerging research topics. Solutions with use of fuzzy logic and neural networks based on input parameters like joint width and depth and output parameters like voltage welding speed and wire feed speed are under development. However, this approach is focussed only on geometrical input parameters from the joint area. The resulting welding process conditions themselves with for instance the arc and molten pool behaviour are not considered.

This project aims to fill this gap by realizing a next-generation fully automated multi-sensor welding machine, driven by a novel self-learning control logic.





What is the potential for further research?

The benefits of well-engineered automated welding systems range from improved weld quality to decreased variable labor costs. The most prominent advantages are:

  1. Improved Weld Quality
  2. Increased Output/Volume
  3. Decreased Scrap/Rework
  4. Decreased Variable Labor Costs







What is the proposed method of IPR-protection? (patent, license, trademark etc.)
IPR-protection requirements and strategies are under investigation







What are the steps that need to be taken in order to secure the IPR-protection? What is the cost of IPR-protection?

If the control-logic is to be tightly coupled with the robot, a patent would be the most effective solution to secure IPR rights.






What is you overall assessment of the scientific maturity of the research result?
The research result has considerable potential but it is currently in the form of an initial idea that needs to be further validated.
