Panel Project – Auto-Identifying Cobot Applications

Slide Note

Discover how collaborative welding robots, or welding cobots, are revolutionizing industrial welding applications. These cobots provide a smaller-defined work envelope, eliminating the need for traditional robot safety cages. Welder/operators can work and collaborate safely with the system, improving productivity. They can handle various welding applications and are easier to use compared to complex automation.

Panel Project Auto-Identifying Cobot Applications 1

What is a Collaborative Welding Robot? Welding cobots are emerging as a viable solution for many industrial welding applications In its current state, it is a robotic welding tool with a smaller-defined work envelope that can be stationary or portable. It does not require traditional robot safety cages and allows personnel to work and collaborate with the system safely in close proximity. This enables welder/operators to fit and weld concurrently while the system is at work, greatly increasing productivity. Collaborative robotic welding systems are commercially available, production-tested and are easily taught to perform welding tasks without the need for traditional robot programming . The welder/operator grabs and manually positions the torch along weld lines and sets desired torch angles. They are untested for the rigorous requirements of shipbuilding. Cobot systems are much easier to use than highly complex automation, but still provide much of the flexibility and power of a larger scale industrial robot. They can handle a much broader set of welding applications compared to mechanized systems such as Bug-O s . Circles and complex shapes 2 Repetitive subassemblies Multipass stacking patterns and nonlinear joints In-process quality control as-needed

What is a Collaborative Cutting Robot? Welding cobots are emerging as a viable solution for many industrial welding applications In its current state, it is a robotic plasma cutting tool with a smaller-defined work envelope that can be stationary or portable. It does not require traditional robot safety cages and allows personnel to work and collaborate with the system safely in close proximity. This enables operators to prep and complete other tasks concurrently while the system is at work, greatly increasing productivity. Collaborative robotic cutting systems are commercially available, production-tested and are easily taught to perform cutting tasks without the need for traditional robot programming . The operator grabs and manually positions the torch along cut lines and sets desired bevel angles. Systems are easy to use and provide much greater cutting precision than manual cuts.

The Case for Collaborative Robotic Welding Arc Time of the Cobot Arc Time of the Welder Significant Increase in Work Force Productivity STRATEGY TO OFFSET WELDING LABOR SHORTAGES Allows a welder and a Cobot to weld simultaneously One can tack & fit components and the other can finish weld Welders and Cobots can work together on the same parts or different parts In many cases, their Combined Total Arc On time can more than double Cobots can be assigned to individual welders or to a group of welders and checked out when needed mobility allows them to move to the work Broad-Spread use of Cobots offers a strategy to reduce hiring & offset labor shortages 4

Cobot Welding is Similar to other forms of Mechanized Welding The Cobot Operator can safely monitor, inspect and dial in or adjust weld parameters to achieve desired specifications Emerging Collaborative Robotic Welding Traditional Accepted Buggo Welding Operator interaction can make weld qualification simpler 5

Outlining a Development Plan for the Auto-Identification of Cobot Welding and Cutting Applications within a Digital Ship Model 2022 Panel Project Proposal PROJECT TEAM 8

Leveraging the digital model to assess Collaborative Robotic Welding & Cutting opportunities This project will focus on outlining a development plan so that potential cobot applications can be easily identified (at the design and production planning stages) from existing and potentially new information contained in and accessed directly from the 3D design and production models. The project will identify general information filtering strategies to help identify Cobot applications that can be leveraged to help ship designers design for cobot applications and production planners to plan for cobot applications . The project will also explore the relationships between information contained in the ERP System if necessary to close the identification loop. Potential Cobot Applications would then be validated before deployment. 9
