Modular laser welding cell: safe laser welding and laser cleaning in your own workshop

Why a modular laser welding cell is indispensable for Class 4 laser

Both the MetaQuip handheld laser welder and the MetaQuip laser cleaner fall under laser class 4. That is the highest class in the laser safety standard: both the beam and its reflections can cause permanent eye and skin damage. Working with this equipment in an open workshop, without shielding, is not an option in practice — neither for your employees, nor within the CE frameworks for which you are responsible as the owner.

Broadly speaking, there are two routes to arrange that safely:

1. Fully equipping an existing space with laser safety using wall coverings, filters, interlocks, and sensors.
2. Install a ready-to-use, modular laser welding cell in your current workshop.

Option 1 works, but is often expensive, time-consuming, and difficult to certify. Option 2 — the modular laser welding cell — immediately provides you with an enclosed, approved working environment without requiring any structural changes to your building.

What exactly is a modular laser welding cell?

A modular laser welding cell is a self-contained, enclosed workspace specifically designed to contain the radiation from powerful lasers. “Modular” means that the cell is constructed from standard panels, allowing it to:

• is available in various standard formats (at MetaQuip: 2×3 meters, 3×3 meters and 3×4 meters, or custom-made),
• is set up relatively quickly on site,
• can be expanded or relocated later if your workshop changes,
• is easy to combine with extraction, filters, and lighting.

In practice, this means that you do not have to adapt your laser welder or laser cleaner to your building — the welding cell adapts to your process.

One modular laser welding cell for two machines: laser welding and laser cleaning

An important advantage of the MetaQuip approach is that you can use the same modular laser welding cell for both machines in our Specials portfolio:

• The handheld laser welder for welding carbon steel, stainless steel, aluminum, titanium, brass, and other metals, with a laser power of 1.5, 2, or 3 kW and a weld depth of up to approximately 10 mm. Read more on the product page of the handheld laser welder.
• The laser cleaner / laser rust remover for removing rust, paint, oils, and other contaminants without chemicals or blasting media. Details can be found on the product page of the laser cleaner.

Both machines benefit from the same shielded workspace, the same extraction system, and the same safety interlocks. For companies that first clean metal and then weld—think of repair work, construction, or restoration—this means you can set up a complete process flow in a single welding cell.

Key features of the MetaQuip modular laser welding cell

The MetaQuip welding cell is designed around practical workshop requirements. The core:

• Multiple standard sizes: 2×3, 3×3 and 3×4 meters, with customisation if necessary.
• Electromagnetic door lock: Can be opened from the outside with a combination lock, and can always be unlocked from the inside — even in the event of a power failure or activation of an emergency stop.
• Standard safety interlocks: The laser can only fire if all guards are closed.
• Combinable with optional extraction and filtration: The cell can be prepared for an industrial filter system such as the BOFA AD 2000 iQ to directly capture welding fumes and cleaning residues.
• Complete furnishing possible: If desired, MetaQuip also supplies the workbench and further equipment, so that the cell is delivered production-ready.

All this means that you receive a ready-to-use, CE-supported working environment that matches the Declaration of Incorporation with which the laser welder and laser cleaner are supplied.

Which size modular laser welding cell suits your work?

The correct size depends on what you do in the cell, not just on the floor space you have available. Some guidelines:

• 2×3 meters — suitable for: smaller workpieces, repair work, light cleaning tasks, and companies that allow one operator to work at a time.
• 3×3 meters — suitable for: General welding and cleaning work on medium-sized parts, with room to move around the workpiece and rotate easily.
• 3×4 meters — suitable for: larger frames, structures, and assemblies, or workshops that combine welding and cleaning phases within a single cell.
• Customization — suitable for: non-standard products (long, wide, heavy), inline production, or specific logistics such as a roller conveyor or forklift access.

Are you unsure which size fits your products? In practice, we often determine this fastest during a demonstration and consultation.

Modular laser welding cell versus making the room laser-safe yourself

Many companies consider modifying their existing space themselves instead of installing a cell. That can be sensible, but there are a few points where the modular laser welding cell makes the difference:

• Speed of commissioning. A modular welding cell can often be installed within a day. Making a room completely laser-safe requires structural modifications and a longer lead time.
• Flexibility. Is your layout changing or are you moving? The modular cell moves with you.
• Clear responsibility. You receive one cohesive security concept (guarding, interlocks, door lock, extraction) instead of separate components from different suppliers.
• Easier maintenance. The cell is documented as a product, ensuring that checks, modifications, and extensions remain manageable.

For companies with high production variety and limited vacant square meters, this is usually the decisive factor.

How the modular laser welding cell fits into a laser-safe workplace

A modular laser welding cell is a powerful component of your laser safety plan, but not the only one. For a complete, CE-compliant workstation, we typically combine the cell with:

• An distance sensor on the laser welding gun, so that the beam is only activated when a workpiece is present within the correct range,
• laser-safe welding helmets (standard basic model or the Panoramaxx for long-term and complex work),
• An industrial air filtration system to capture vapor and particulate matter directly at the source,
• safety protocols and training for every operator, including emergency procedures.
