Laser Welding Series - Talking Safety with David Werba (Full Weldcast)

Handheld laser systems are rapidly moving into welding, cleaning, cutting, marking, and surface‑prep applications — and they’re showing up in shops of every size. But while the accessibility of these tools is increasing, the safety culture around them hasn’t caught up. Laser radiation is concentrated, often invisible, and fundamentally different from arc welding light. That means welders and fabricators now face a completely new set of rules. In this episode, David A. Werba joins us to break down what safe laser operation really requires. Dave has spent years in the welding industry as a Senior Electrical Engineer, Manager of Product Design Compliance, and an active leader on multiple national and international standards committees. Today, he’s deeply involved in the development of laser safety standards, helping guide how handheld systems should be safely designed, used, and integrated into real‑world operations. Dave explains why LASER‑RATED PPE, enclosures, barriers, and controls are not optional — they’re mandatory. And he walks us through the key considerations welders and shop owners need to understand as handheld laser systems become more common across the industry. What We Cover in This Episode: 👉Why laser safety is a growing concern today — and how the rise of small, handheld laser systems has brought high‑power laser technology into everyday welding and fabrication shops that may not have prior experience with laser hazards. 👉The three primary hazard categories welders must understand: optical hazards, skin exposure, and adjacent fire risks — and why these require laser‑rated PPE instead of traditional arc‑welding gear. 👉The importance of engineered safety features in laser products and controls, including proper interlocks, enclosures, signage, and laser‑controlled area considerations. 👉Key standards and updates on the horizon, especially the upcoming revision of ANSI Z49.1, which will include guidance specific to handheld laser systems for the first time. As lasers become more accessible, the responsibility grows with them. Whether you’re a one‑person shop or a large manufacturer, safe implementation comes down to training, awareness, and proper precautions. A huge thank‑you to Dave — and to all the experts who volunteer their time to develop these standards. Their work gives all of us a clear roadmap for what to look for in a laser system and how to safely integrate this technology into our operations. Stay safe out there… keep your hood down, and don’t stare at the invisible light. (HAHA!) 📌 Guest Participation Disclaimer David A.
