burns, or flash burns, is a painful ocular condition
sometimes experienced by welders who have failed to use
adequate eye protection. It can also occur due to light from
sunbeds, light reflected from snow (known as snow
blindness), water or sand. The intense ultraviolet light
emitted by the arc causes a superficial and painful keratitis.
11. Stainless
steel
K
Triatomic molecule, consisting of three oxygen atoms. It
is an allotrope of oxygen that is much less stable than the
diatomic species O2. It is a pale blue gas at standard
temperature and pressure. It forms a dark blue liquid below
−112 °C and a dark blue solid below −193 °C. A powerful
oxidizing agent. It is also unstable, decaying to ordinary
diatomic oxygen: 2 O3 → 3 O2.
12. Arc eye
L
From Greek τοξικότητα – poisonousness). It can refer to
the effect on a whole organism, such as a human or a
bacterium or a plant, or to a substructure, such as the liver.
By extension, the word may be metaphorically used to
describe toxic effects on larger and more complex groups,
such as the family unit or "society at large". The skull and
crossbones is a common symbol for it.
13. Tungsten
M
Forms of protective eyewear that usually enclose or
protect the eye area in order to prevent particulates or
chemicals from striking the eyes. They are used in
chemistry laboratories and in woodworking. They are often
used in snow sports as well, and in swimming. Goggles are
often worn when using power tools such as drills or
chainsaws to prevent flying particles from damaging the
eyes.
14. Voltage
N
Electromagnetic radiation with a wavelength shorter than
that of visible light, but longer than soft X-rays.
Speaking
True or false?
1. Filler material is always necessary for arc welding.
2. The amount of heat input at the welding point depends on the voltage.
3. Shielded metal arc welding is a consumable electrode process.
4. Consumable welding processes use any type of current.
5. Consumable electrode methods are faster than none-consumable ones.
6. TIG welding requires little operator training.
