The welding sector is facing an ecological turning point: a market that employs over 20.000.000 professionals, with a turnover of over 40 trillion euros, that wants to evolve, innovate and embrace a greener processing policy. What are the problems with the highest environmental impact? And what are the possible solutions? Let’s see them together.
The number of people employed as Welding, soldering, & brazing workers has been growing in the last 5 yearat a rate of 4.98%, in the usa alone from 580,520 people in 2018 to 609,457 people in 2019.
First of all, we need to talk about the most dangerous emissions into the atmosphere from welding, both for professionals and for those who use the finished product.
One of the most important risk factors for you, especially for operators, comes from the radiation emitted during welding: the most dangerous are ultraviolet radiation, as it is absorbed almost entirely by the skin and eyes. The protection of each exposed area is the most effective solution. Much les dangerous is the infrared light radiation.
Welding fumes, on the other hand, are a very different problem: the effect changes according to the welded metal, going from problems with the respiratory system to damage to the skeletal system. For this reason, during welding, the work area must be well ventilated, or equipped with the right suction machinery.
Another element that requires suction are the so-called welding powders, very small particles of material with high toxicity and capable of penetrating the respiratory system. Electrode welding has the highest concentration of dust among all welding techniques, so you need to protect yourself with a mask
An action with a dual value: reduction of emissions and increase in productivity of each welding process.
One of the solutions, today, seems to be the use of electronic parts instead of electrical components for the construction of welding generators: we talk about energy savings of up to 25~35% compared to conventional welding units. Given the advance of increasingly smaller and more portable equipment, this goal seems to be fullfilled already in the last years and all the offered equipment is fully electronical.
But the biggest energy savings can be obtained by changing the conventional welding to the very high efficient laser welding, which can reduces the energy consumption till 90%! Thats real savings!!!
Emissions are reduced through the use of new consumable products (such as electrodes), which are technologically advanced and less subject to the release of fumes and dust. With laser welding we use only wire out of the same metal as th eone welded as consumable, which is only melted and does not need special treatment or covers. Much less fume with laser Welding;
