Why Welding Robot Safety Standards Matter
No single standard covers an entire robotic welding installation. Instead, manufacturers and integrators work through a matrix of overlapping standards from OSHA, ISO, ANSI and the American Welding Society (AWS).
Key Standards
| Standard | Scope | Key Requirements |
|---|---|---|
| ISO 10218-1/2:2025 | Robot design and system integration | Functional safety, collaborative modes, cybersecurity |
| ANSI/A3 R15.06-2025 | U.S. adoption of ISO 10218 | Risk assessment, safety-rated soft limits |
| AWS D16.1M/D16.1:2018 | Arc welding robot systems | Program verification, trained observer, welding hazard control |
| ISO/TS 15066:2016 | Collaborative robot force limits | Biomechanical pain thresholds |
| OSHA 29 CFR 1910.147 | Lockout/Tagout (LOTO) | Energy isolation before servicing |
Major 2025 Revisions
Both ISO 10218-1:2025 and ISO 10218-2:2025 superseded the 2011 editions—the first major update in 14 years. The new version incorporates collaborative robot requirements directly, introduces cybersecurity requirements for safety functions and launches a robot classification system.
Practical Safety Measures
- Conduct a risk assessment before commissioning.
- Use perimeter guarding for industrial robots.
- Verify programs before arc start.
- Train operators and maintenance personnel.
- Function-test emergency stops and light curtains regularly.
