Welding and cutting filter solutions

Dangerous gases and smoke generated by the welding and cutting industry

The welding and cutting industry can generate dangerous gases and smoke containing particles of various oxides, which can harm 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, other processes 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 processes can reach the cells of the human body, thereby triggering illnesses caused by cell mutation. The good news is there is an easy way out and it’s called a welding fume extraction system.

Filtration solutions for welding and cutting processes

An extraction source is one of the most effective ways to remove welding fumes. Businesses must 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 welding fume extraction is important

In many welding and cutting processes, harmful fumes are generated and require a proper dust filtration and collection solution.
In many welding and cutting processes, harmful fumes are generated and require a proper dust filtration and collection solution.

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 different factors, for instance, generation rate, frequency and duration of operations, 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.

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) .

Using dust collectors for welding fume extration in cutting and welding processes

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. Two basic hood designs 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 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.

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. Teldust is the leader in designing customizable dust collectors that are efficient and affordable.
