Welding ventilation and its necessity

20 December 2021

More and more attention is being paid to the well-being of workers in production, including in welding shops, as blue production is a sign of poor welding ventilation.

There are several different ways to make welding safer:

The most effective way is to use a spot tensioning system, either. retrieval cage or welding cube form.
Due to a large welding shop or large workpieces, it is possible to use forced welding ventilation, commonly referred to as. Push-Pull a solution where air is sucked out of the production process, purified and forced back into the same space.
In smaller production plants, it is also possible to use a stationary system. Welded filter tower, which cleans the area around the weld filter. The unit has a capacity of up to 8000m3/h.
Confining welding fumes, whether in the form of curtains or louvres, can also help to keep nearby workers healthy.

Because welding fumes vary depending on the metal, some metals may even miss the problem, while the health risk is much greater.

The most common gases found in different types of welding methods/separate metals:

Nitrous oxide
Carbon dioxide
Carbon monoxide
To

Welding fumes can also contain various metal particles:

Kroom
Nickel
Tsink
Manganese
Cobalt
Iron

All of the above substances pose a serious health risk, which can take the form of asthma, Parkinson's disease or cancer. In addition, small diameter particles also cause serious damage to the lungs and respiratory tract of humans.

So how can we get rid of these dangers?

Exhaust of welding fumes and vapours from the vicinity of the point of generation

In this sense, the most effective way to get rid of hazardous welding fumes is to. with welding studs solution.

Unfortunately, if the parts to be produced are often variable or too large in size, the use of a pick and place arm can prove very cumbersome and time consuming. In the worst case, operators will not use the equipment they have already purchased.

In this case, it makes sense to use the welding process in the area above the retrieval cube.

In addition to the extraction cube, it is also advisable to add louvres to reduce the air volume required for extraction. It is also possible to add the lighting required for the workstation to the welding cube.

Forced ventilation or Push-Pull

In larger industries, where the use of precision edging systems is too time-consuming or even impossible, it is common to use. Push-Pull welding ventilation solution. There are a number of different methods of dealing with the plumbing issue in this case, but primarily it depends on an individual basis on the specific nature of the customer's work and the production premises.

What we offer welding filters purify 99.9% of the air to be extracted and return the already purified air to the production process.

Push-Pull advantages:

uninterrupted operation thanks to automatic filter cleaning by a special automatic pressure sensor;
reduced heating costs - air is cleaned and recycled back into the industry without losing heating energy;
automation can be used to ensure that the filter starts and stops depending on the welding process - the filter will not operate if no welding is taking place, and it is also not possible to "forget" to switch the filter on;
collection tanks with filters;
possibility to place the equipment outdoors/on a frame to save industrial space or reduce noise levels.

Welding filter tower "Airtower"

Welded filter "Airtower" is very practical for smaller industries where the welding process takes place in smaller spaces. As the unit is plug-and-play (plug in and run), then only a mains supply and compressed air are required for the filter to operate.

Welding filter towers are available in two different capacities: 5500m3/h and 8000m3/h.

The filters of the device are cleaned by compressed air and the lifetime of the filters is considered to be 4000-6000 operating hours! The lower part of the unit has a collection box where the heavier dust collects.

Get in touch and ask for a demo to make sure it's working well before you buy.

Welding curtains/slats

The simplest way to limit the spread of welding gases is to use welding curtains/flaps. Welding curtains are available in both fixed and mobile solutions.

In addition, the welding booths can be successfully enclosed with slats, ensuring continued convenient operation and transport of parts in/out.

Fresh air in production

With a welding filter, we can ensure that the air in the production area is cleaned of residues, but we do not guarantee the fresh oxygen that people and the welding process need. To do this, it is essential to think about securing fresh air.
