Overview

An internal R&D effort that builds a robotic welding process simulation environment in Isaac Sim to test whether the process can be validated virtually before real-world deployment.

Project Background & Purpose

In a virtual environment based on NVIDIA Isaac Sim, we internally validated the process by which a 6-axis robot detects weld seams and plans its path from the WPS (Welding Procedure Specification) through to the welding and inspection sequence. Validating a welding process directly on-site with a real robot is costly and risky, so we set out to secure, through internal R&D, a way to check process timing, robot reachability, and weld sequencing first, without physical hardware.

Components

• NVIDIA Isaac Sim / Omniverse simulation environment
• 6-axis welding robot model
• WPS-based path planning module
• DES cell-level production scheduling
• MES/AAS task-status sync

Process Steps

1. 1Build the target weld structure and virtual work environment in Isaac Sim
2. 2The 6-axis robot detects weld seams and plans its path from the WPS
3. 3Simulate the weld-and-inspect sequence in the virtual environment, validating process timing and robot reachability
