AI-Powered Multi-Robot Systems for Flexible Welding and Metal Part Repair

manufacturingPilotedTRL 6

Imagine a team of robots working together like a pit crew. Instead of using expensive custom clamps to hold a part in place, two robots hold the piece perfectly while a third one welds it. It also works like a high-tech 3D printer to fix expensive broken metal tools instead of throwing them away.

The business problem

What needed solving

High-mix, low-volume manufacturing is currently slowed down by the need for expensive, custom physical jigs for every new part. This creates high tooling costs and long lead times that make small-batch production unprofitable.

The solution

What was built

A digital platform for multi-robot coordination and two functional multi-robot cells capable of jigless arc welding and WAAM-based metal repair.

Business applications

Who can put this to work

Automotive
enterprise
Target: Custom vehicle manufacturer

If you are a custom vehicle manufacturer dealing with high-mix, low-volume production and costly custom jigs — this project developed a jigless robotic welding system that eliminates dedicated physical fixtures. This reduces tooling costs and shortens lead times for small-batch manufacturing.

Toolmaking
SME
Target: Industrial mold and die shop

If you are an industrial mold shop dealing with damaged high-value components — this project developed a multi-robot WAAM repair system. It uses a processing robot and an auxiliary robot for 3D scanning and preheating to restore expensive tooling.

Aerospace
mid-size
Target: Specialized metal component fabricator

If you are a fabricator dealing with complex geometries that require constant machine reconfiguration — this project developed a digital platform with AI models that allow fast adaptation of processes. This ensures high product quality while lowering energy consumption.

Frequently asked

Quick answers

How does this reduce production costs?

It implements a jigless welding approach where robots hold the workpieces, eliminating the need for expensive custom jigs and fixtures. This specifically lowers tooling costs and lead times in high-mix, low-volume settings.

Is this solution ready for industrial scale?

The project targets TRL6, meaning it is validated in two semi-industrial pilots for the automotive and toolmaking sectors. Based on available project data, it is designed for high-mix, low-volume industrial production.

What are the IP and licensing options?

Based on available project data, the project involves 9 partners and 15 external third parties via an Open call, but specific licensing terms are not provided.

How is the system integrated into existing factories?

The project delivers a digital platform with interoperability capabilities for data management and cognitive human-machine interfaces. This allows the multi-robot cells to be integrated into a flexible production environment.

What is the timeline for deployment?

The project period runs from 2023-10-01 to 2026-09-30, with the final validation of semi-industrial pilots occurring within this window.

Consortium

Who built it

The consortium is well-balanced for commercialization, consisting of 9 partners across 6 countries. With a 33% industry ratio (3 industrial partners, including 2 SMEs), there is a strong link between the 2 universities and 1 research center and the actual market needs of the automotive and toolmaking sectors.
