Electric contact welding
This process may be accompanied by the formation of molten metal particles that fly apart at high speed. Therefore, you should protect your eyes and skin.
Arc welding
This process is accompanied by strong ultraviolet radiation, which can cause damage to the eyes and skin burns of the welder and people nearby. In this aspect, welding processes in a shielding gas environment are especially dangerous. Personal protective equipment should be used. The welding area should be fenced off with special screens that protect the rest of the personnel.
WHEN PERFORMING WELDING, PERSONS WEARING CONTACT LENSES ARE RECOMMENDED TO REPLACE WITH REGULAR GLASSES, because. there is reason to believe that the spectrum of the welding arc emits microwaves that dry out the liquid between the lens and the eye. As a result, when the lenses are removed from the eyes, it can lead to blindness.
Molten metal splashes may also be sprayed, so appropriate eye and skin protection is required.
The heat of the welding arc leads to the release of vapors and gases from the materials being welded, electrodes and from any coatings and dirt located on the surface of the workshop floor, equipment, etc. These gases and vapors can be toxic and should not be inhaled. Exhaust ventilation may be required to remove fumes and smoke from the work area, especially where general ventilation is poor or when a large amount of welding is planned. In extreme cases, or when welding in confined spaces where good ventilation cannot be provided, it may be necessary to use vented respirators.
CAUTION: Some parts of the vehicle, such as the inner cross member and the cross member of the engine compartment, are made of magnesium alloy. Under no circumstances should these parts be boiled.
Gas welding (and cutting)
Oxy-acetylene torches can be used for welding and cutting. Greater precautions must be taken to prevent leakage of these gases, as this entails the risk of fire and explosion.
The process will be accompanied by the formation of splashes of molten metal, so the use of eye and skin protection is necessary.
The flame in gas welding is very bright and therefore eye protection should be used, but the emission of ultraviolet radiation is much less than in arc welding; you can use lighter filters.
This process releases some toxic substances (in the form of smoke). Vapors and gases can also be released from coatings, especially when cutting off damaged body sections. Inhalation of these gases and vapors should be avoided.
When brazing, toxic substances can be released from the metals that make up the solder rod. There is a serious danger if rods containing cadmium are used for soldering. In this case, extreme care must be taken to avoid inhaling harmful vapors. Expert advice may be required.
WHEN WELDING OR CUTTING CONTAINERS CONTAINING COMBUSTIBLE MATERIALS, SPECIAL PRECAUTIONS SHOULD BE TAKEN - IN THE CASE OF FUEL TANKS, THEY MUST BE BOILED OR STEAM-CLEANED.
