Filter Solutions for the Welding Industry

Dangerous gases and smoke containing microscopic particles

The process of welding can generate dangerous gases and smoke containing particles of various oxides, which can be harmful to health. The size of the particles released from welding can influence the levels of toxicity in the fumes, with smaller particles posing an even larger threat. Apart from that, there are other processes that can produce gases (ozone and carbon dioxide) which can be lethal if there is inadequate ventilation at a facility.

Fine dust and particles produced from welding prosesses can reach the cells of the human body, and thereby triggering illnesses caused by cell mutation.

As a result of this, welding fumes have been classified as a cause of lung cancer by the World Health Organization and the International Agency for Research on Cancer (IARC) .

The good news is there is an easy way out and it’s called a welding fume extraction system.

Filter Solutions

An extraction source is one of the most effective ways to remove welding fumes. It is critical that businesses choose the most effective extraction solution for the removal of harmful fumes and particles from the air at their facility. However, the choice of air filter you go with will ultimately depend on what you are going to use extraction for and how often will you be using the extraction system for process gas.

Why is Welding Fume Extraction Important?

During a thermal cutting (e.g. laser beam cutting, plasma arc cutting and oxyfuel flame cutting) process, the generation rate of gases and fumes will vary according to the composition of the base metal, fillers and fluxes, and also on the rate and depth of the cutting or welding process. This means the level of exposure of the operator is going to vary depending on various different factors, for instance, generation rate, frequency and duration of operations, along with work practices, and the efficiency of the ventilation. This is why having a proper welding filter is so crucial to better air quality at a facility.

 

Welding Filter Recommendations

The first thing that business owners need to focus on when it comes to welding fume extraction is the hood design of their filtration system. There are two basic hood designs that are most commonly used for welding fume extraction. For instance, enclosed hoods are considered to be far superior and more effective in controlling various welding contaminants that are released into the air as a result of the welding process. On the flipside, the enclosed hood can restrict the access to the filtration system and could lead to reconsidering the choice of material and the handling of the filtration system. The second option is capturing hoods, which are considered to be less effective as compared to enclosing hoods but can deliver adequate results when used appropriately.

Using Dust Collectors for Welding Fume Extraction

Solution: Dust collector

Due to the variations in welding particles that are produced during cutting applications, dust collectors can be another effective way of extracting process gases.

Solution: Cartridge collectors

The more traditional option are cartridge collectors due to their compact size.</p> <p>Teldust is the leader in designing customizable dust collectors that are efficient and affordable.
