Welding fume extraction for sound, safe and efficient metal fabrication and cutting processes
Welders face a series of risks from dangerous substances that could mean they face time off work for illness or even early retirement. Different welding methods give rise to different amounts of fumes containing various concentrations of hazardous substances. The smaller the particles, the more dangerous they become because they are easier to breathe in deeply in the lungs. The amount of welding fumes that are formed depend upon the type of welding and materials used.
Nederman offers a full portfolio of portable, stationary, central and custom engineered solutions to control and mitigate welding fume and cutting smoke within the production environment from common welding processes, including MIG, TIG, GMAW, FCAW or SMAW. With over 60 years of industry experience, we can provide application review, solution recommendation and implementation, system design, engineering and installation, product and system support, commissioning, diagnostic and service maintenance programs, upgrading older systems, assistance with meeting clean air regulations and standards, and energy efficient solutions.
Automated and robotic welding
Semi-automated and robotic welding applications utilize precise machinery and electronic controls to perform welding and cutting operations that used to be routinely performed by a welder. Since the mechanical device or robotic arm is performing the welding process, fume arms are difficult as fume arms need to be moved near the weld point to efficiently capture the fume. Nederman solutions for semi-auto and automatic welding processes include both on-torch and canopy hoods for welding fume extraction.
As an alternative to the hood and arm fume extractor, on-torch or integrated welding fume MIG gun extraction can be used. The on-torch extraction systems extract the fumes directly from the welding torch without interfering with shielding gas. The extraction systems are available as both mobile single user extraction units and central extraction systems serving several extraction points.
Some thermal cutting processes include oxy-fuel, air carbon arc gouging, plasma arc cutting and laser cutting. These processes can vary from a small to large applications. High heat, molten metal and fume particulate are some of the by-products of these processes. Solutions vary from one application to another, however in many cases, the fumes generated from the cutting process are extracted through grates on an elevated table. Other solutions proven effective include close source capture, overhead hood systems, and in a some cases ambient filtration.
Extraction at source
Extraction at source is the most effective way to collect and remove fumes. Choose the most effective solution for your workplace! Nederman has different solutions for getting rid of fumes and particles. Your choice depends on what you are going to use extraction for and how often you will use it.
