Automated Robotic Welding

Main objective

 

The objective of the demonstrator is to showcase how an industrial robot can be used for robotic welding and wire arc additive manufacturing (WAAM).

Short description

The industrial robot has an important role in the automation of the manufacturing industry and has considerably contributed to the improvement of profitability and working environments. However, there are still many tasks in the manufacturing industry that requires heavy work, such as welding and additive manufacturing based on welding.

Potential users

Manufacturing Industry, Automotive and Aerospace Industry

Benefits for the users

– The demonstrator exploits an industrial robotic arm to automate repetitive welding jobs that result in more consistent welds and fewer mistakes.  

– Remote programming of the system (offline programming). This allows for verification of the welding program before running it on the physical robot and you can program the system without interrupting the current production which can save costs.

– Using robotic welding releases humans from the labor-intensive and hazardous work environment.

– The system can be used for additive manufacturing, to repair broken parts or 3D print parts. This can be a fast and cost-effective method to create or fix damaged parts.

Innovation

Robots are usually programmed with a robot controller and the physical robot to teach positions. This demonstrator uses a simulation software as a programming tool and a digital twin copy of the physical robot for robot programming.

The system allows for remote programming and configuration without being physically in the production environment. This creates a flexible method for re-programming and the possibility to test the program in the simulation software before executing it on the physical system.

Risks and limitations

– Welding induces a lot of stress on the welded part. This has to be considered when using the system for additive manufacturing with a TIG welder.

– Since robots are connected through the internet, further consideration on cybersecurity should be done to avoid cyber attacks.

– Using TIG welding for additive manufacturing produces considerable heat, which requires a lot of cooling.

Technology readiness level

6 - Safety approved sensors and systems are commercially available

Sectors of application

Aerospace - the parts created from the demonstrator have strong features, Automotive - the demonstrator has significant use as a single car can require thousands of welds in assembly, Manufacturing - performing repetitive work which can easily be automated with a robotic welder, Petroleum industry - welding oil and gas pipelines..

Potential sectors of application

3D printer for Aerospace and Automotive industry
