Fume extraction in welding applications

Ensuring proper fume extraction in welding applications is crucial for preventing serious health risks among welders, enhancing productivity, and maintaining compliance with safety standards.

Welding processes, including MIG, TIG, stick, FCAW, and laser welding, generate hazardous fumes classified as Group 1 carcinogens by the International Agency for Research on Cancer (IARC). Effective fume control is essential to protect worker health, maintain productivity, and meet regulatory requirements.

Nederman delivers a complete approach to weld fume control — combining capture, high-efficiency filtration, intelligent monitoring, and regulatory expertise to create welding environments that are safe, productive, and energy efficient. Our solutions help manufacturers maintain air quality, support compliance, and protect both people and operations.

Choosing the right welding fume capture method

An effective fume extraction system begins with capturing fumes where they are generated. Because every welding process, material, and workspace is different, Nederman provides a full range of capture methods tailored to your application, facility layout, and production requirements.

On-torch welding fume extraction - Extraction integrated directly into the welding torch captures fumes at the point of generation, preventing migration into the operator’s breathing zone and surrounding workspace. This approach is highly effective for manual welding and collaborative robotic applications where consistent positioning can be maintained. Learn more about on-torch welding fume extraction here.

At-source welding fume extraction - Local exhaust ventilation (LEV) systems capture fumes at or near the source using extraction arms, downdraft tables, or cross-draft hoods. Properly designed and positioned systems provide effective protection while preserving welder mobility and productivity.

Local containment for enclosed fume extraction - When direct source capture is difficult, such as with robotic welding or large components, containment systems enclose the welding process and extract fumes before they disperse throughout the facility. Solutions may be fixed or retractable and mounted to floors, fencing, or ceilings. Discover Nederman’s Streamline Modular Hood >

Ambient air filtration - For applications where source capture or containment is limited by part geometry or process constraints, ambient air filtration systems clean the surrounding air. By creating controlled airflow patterns, these systems remove residual fumes and return filtered air to the workspace, improving protection while reducing energy loss from exhausting conditioned air.

Filtration solutions for welding fume

Capturing weld fumes is only the first step. The next is ensuring hazardous particles are effectively removed before air is recirculated or exhausted.

Whether your operation involves light fabrication or high-volume automated production, our filtration systems are engineered to handle the fine, complex particulate generated during welding. From mobile units for individual workstations to centralized systems serving entire facilities, our technologies deliver clean air, dependable performance, and long-term efficiency.

Filter technology

Weld fume particles are extremely small, with nearly all measuring less than 1 µm, requiring filtration capable of capturing submicron particulate. Filter media rated ISO ePM1 and MERV 13 or higher are critical for effective removal.

For highly toxic materials such as stainless steel welding, safety after-filters including HEPA filtration may be required, particularly when air is recirculated into the workspace.

Advanced surface-loading media such as nanofiber or ePTFE membranes keep particulate on the filter surface, improving cleaning efficiency, extending filter life, reducing pressure drop, and lowering energy consumption.

Optimise performance and reduce downtime through digital monitoring

Sensors and digital monitoring systems provide continuous insight into extraction system performance. By tracking airflow, differential pressure, and filter condition, operators can detect issues early, maintain consistent air quality, and optimise maintenance.

This data-driven approach reduces unplanned downtime, improves productivity, and lowers operating costs while ensuring reliable protection.

Compliance with welding fume regulations and occupational exposure limits

Weld fume control systems are essential for meeting occupational health and environmental regulations worldwide. Authorities such as OSHA, the UK’s HSE, EU directives, and ACGIH establish exposure limits for hazardous airborne contaminants.

Exposure limits vary by substance but are typically very low. For example, total welding fume limits are often around 1–5 mg/m³ (8-hour TWA), while specific toxic components such as manganese may be limited to approximately 0.02–0.2 mg/m³, and hexavalent chromium (Cr VI) as low as 0.005 mg/m³ (5 µg/m³).

Because requirements differ by region and application, facilities should consult applicable to local regulations when designing fume control systems. Nederman solutions help manufacturers maintain compliance by controlling exposure, maintaining safe air quality, and documenting system performance.
