How to Choose the Right Laser Welding Screen to Secure Your Production

Understanding the Risks Involved in Establishing a “Laser Controlled Area”

The deployment of an industrial laser, particularly in a handheld configuration, requires the creation of a Laser Controlled Area. This is a strictly regulated area in which every access point must be secured. Choosing a screen is not a matter of aesthetics, but a direct response to hazards that cannot be detected by human senses.

Invisible Hazards: UV Radiation and Scattered Beams

Eye injury is the primary hazard. In addition to the direct beam, scattered beams (reflections from metallic or polished surfaces) and UV radiation can cause irreversible retinal damage or severe skin burns, even from a distance. A standard arc welding screen is completely inadequate in this situation; only a barrier capable of blocking specific wavelengths and withstanding high irradiance can provide effective protection.

Secondary Hazards: Heat and Hot Spatter

The laser fusion process generates high-temperature sparks, flying debris and metal fumes containing fine particles. The LZRTect screen acts as a thermal containment enclosure, protecting the rest of the facility against fire hazards and facilitating the local extraction of harmful gaseous emissions.

This control of physical hazards forms the foundation of LZRTect’s technological innovation.

LZRTect Innovation: Active, Certified Protection

The Rolltect/LZRTect solution was designed to go beyond basic passive protection standards. It transforms a physical barrier into an intelligent safety management system.

Thermal Performance and Irradiance Resistance

The critical factor for any industrial decision-maker is the resistance threshold. LZRTect screens can withstand a maximum irradiance of 250 W/cm². This specification ensures that, even if the beam is accidentally deflected, the screen continues to act as a protective shield, providing sufficient time for the safety systems or operator to respond.

Active Safety and Hardware Interface

The key innovation lies in the integration of a magnetic interlock. Unlike conventional curtains, the LZRTect screen can be connected directly to the laser’s safety interface. This system ensures that the laser cannot be activated unless the screen is fully deployed and that it shuts down immediately if the barrier is opened or breached. This “active safety” system eliminates the risk of human error.

The technical performance of these screens is complemented by an ergonomic design created to support agile production.

Flexibility and Mobility: Optimising Production Space

Laser protection should not permanently take large areas of a facility out of use. Modularity is the key to cost-effectiveness.

Retractable Design for a Minimal Footprint

Thanks to a robust roller-tube system and J-hooks, the screen can be deployed within seconds to isolate an operation, then fully retracted to free up floor space. This responsiveness is essential in multifunctional environments where every square metre must remain productive.

Strategic Mobility: Wall Mounts vs Mobile Bases

• Wall mounts: Designed for dedicated welding cells.
• Mobile bases: Allow the safety system to be moved to wherever the workpiece is located. This flexibility avoids taking large sections of the workshop out of service with costly fixed partitions.

This operational versatility is particularly valuable when using advanced handheld equipment.

The Specific Case of the IPG LightWELD: Why Generic Solutions Fall Short

The growth of handheld lasers such as the IPG LightWELD is redefining safety requirements. The mobility of the laser statistically increases the risk of the beam being accidentally directed towards an unprotected area.

Optimised Protection for Handheld Lasers

Generic protective solutions are not designed for the specific irradiance levels and wavelengths of modern handheld systems. LZRTect screens are specifically tested for these configurations, providing a barrier whose optical density and thermal resistance are ideally matched to the power of these precision tools.

Ergonomics as a Guarantee of Consistent Use

Complex safety equipment will eventually be bypassed. The simplicity of the LZRTect system and its intuitive deployment help ensure that operators use the protection consistently, even for quick tasks. This strengthens the safety culture without slowing down production.

Beyond its operational benefits, this solution is also a strategic tool for achieving compliance.

Investment and Compliance: A Decision-Maker’s Perspective

Investing in LZRTect means choosing long-term durability while reducing the organisation’s civil and criminal liability.

Cost Reduction and Asset Management

Rolltect’s modular approach helps optimise investment. A single mobile screen can successively secure several workstations, replacing multiple costly and inflexible fixed installations.

Reducing the Laser Safety Officer’s (LSO) Liability

The LSO is responsible for validating the compliance of working areas. Installing certified LZRTect solutions makes this process easier by including the required safety signage (Danger/Warning) and providing clear technical assurances. For the LSO, this helps ensure reliable compliance while significantly reducing the company’s legal exposure in the event of an inspection or accident.
