Welding and soldering smokes

Responsible companies ensure that welding fumes and soldering fumes are removed from the workplace to protect workers from illness. This is because welding and soldering fumes are among the most common causes of respiratory diseases in workers in the metal industry.

Welding and soldering release gases and particles in the form of welding fumes, due to the chemical process that occurs when the material is heated. This welding fume poses a health risk to workers, and therefore, effective removal of welding fume in the workplace is extremely important. Welding fumes can cause a wide range of complex and serious diseases in workers exposed to the fumes over a long period of time. This is precisely why the health and safety of workers should come first. Welding fume extraction helps to create a better and safer working environment for the benefit of all.

A short video about extraction of welding fumes

In all types of welding, it is very important to protect workers from toxic fumes. A powerful point extraction by means of an extraction arm will ensure a healthy working environment.

The extracted smoke passes through an efficient filter, which cleans the air before it is discharged into the open air.

To achieve optimal extraction, a corrosion-protected fan is used, which is controlled by an automatic control unit. This way it is ensured that the extraction starts when welding is taking place and that energy consumption is kept at a minimum.

    EXTRACTING WELDING FUMES AND SOLDERING FUMES

    WHAT ARE WELDING FUMES AND SOLDERING FUMES?

    Welding fumes and solder fumes are formed by the evaporation of the material being welded, welding electrodes and solder, and the filler material used in the process. Various chemical substances are formed during welding and these are both visible and invisible. Welding fumes consist of both gases and fine dust, and particles so small that they are described as nanoparticles. The fumes can contain a number of metals, such as iron, copper, manganese, chromium and nickel. Nickel, chromium, and welding fumes are currently on the list of carcinogens. This makes the decision on the extraction of welding and soldering fumes even more important.

    RULES AND LEGISLATION

    The metal industry is constantly evolving, and this also places demands on the equipment being worked with – the equipment must be able to cope with innovations in materials and manufacturing processes, for example. As a company owner or responsible for production in the metal industry, it is important to keep up with these developments so that employees can be protected in the best possible way in hazardous situations, such as the emission of welding fumes. Although employees as welders are obliged to use the safety equipment provided, it is the employer’s responsibility to provide equipment that meets the requirements at the time. If the employee becomes aware of a problem that affects safety in the workplace, they must report this to their employer or safety representative. It is important that the employer and safety representative ensure the safety of the work environment and that the work equipment complies with local and national laws and regulations. At the same time, it is also important that regular checks are carried out on products, the working environment and safety, as several factors can affect the effectiveness of extraction. These can be, for example, changes in work processes, new employees, changes in materials used, etc. By controlling work areas and safety, the risk of serious health problems can be prevented.

    EXTRACTION OF WELDING AND SOLDERING FUMES

    Good and effective prevention can eliminate many of the serious health problems and help create a better working environment. To minimise or eliminate the safety risks associated with welding and brazing, it is important that the workplace is well ventilated. This means that contamination is removed as far as possible at source, both to look after the employee who is welding, but also other employees who are in the vicinity. It is a good idea to carry out a risk assessment of the workplace to see where action is needed. Including how much welding fume and soldering fume is being emitted. However, it is always important to focus on ventilation, no matter how long the welding is going on or how many workers are around the welding or soldering site.

    Extraction of welding and brazing fumes is often called process extraction. Process extraction can work in several ways, including point extraction at the individual workplace. What the various options for process extraction have in common, however, is that they all protect against welding fumes and the hazardous elements that are released into the air.

    Typically, the fumes will be exhausted via an extraction arm or a hood. By creating a negative pressure in the extraction arm and the collector, the smoke is drawn away from the workplace. The negative pressure is created by a fan, which can be mounted directly on the extraction arm or at the hood, but often it will be mounted at the end of the extraction system and often outdoors.
    A filter is fitted between the extraction arm and the extract unit and the fan to filter the air of harmful smoke particles so that they do not spread outside the building.

    We offer a range of products for process extraction, including extraction arms, collectors and industrial filters for cleaning the extracted air. The products are available in many types and dimensions, and we offer a wide range of accessories to provide our customers with a complete solution.
