Controlling these fumes and gasses during welding is essential to welders and its environments.
Different welding methods give rise to different of fumes containing risk to health and unsafe environments.
Welding is classified into two groups: Fusion (heat alone) or pressure (heat and pressure) welding.
There are 3 types of fusion welding, namely electrical arc, gas and thermit.
Particulate fume is formed mainly by the vaporization of metal and flux. As it cools, the vapour condenses and reacts with the atmospheric oxygen to form fine particles.
This size of the particles (0.01 – 1 micron) tends to influence the toxicity of the fumes, with smaller particles presenting a greater danger.
Health effects of breathing welding fume:
Airborne particles from 2 weeks welding. One single welder produces 20-40 & fumes per hour which correspond to about 33-70 ka ver year
For Welding Fume, it’s recommended to use at least a P3 HEPAC filters
The use of a face mask is a means of the solution to the smoke and dust intake that is in the workshop.
The availability of this system can improve the security and efficiency metal manufacturing and cutting process.
