4. Alternating
current (AC)
D
(from the Greek άνοδος = 'going up') is the electrode in a
device that electrons flow out of to return to the circuit.
Literally, the path through which the electrons ascend out
of an electrolyte solution. The other charged electrode in
the same cell or device is the cathode.
5. Oxidation
E
In metallurgy, a substance which facilitates soldering,
brazing, and welding by chemically cleaning the metals to
be joined. Common ….s are: ammonium chloride or rosin
for soldering tin; hydrochloric acid and zinc chloride for
soldering galvanized iron (and other zinc surfaces); and
borax for brazing, and welding ferrous metals.
6. Goggles and
safety glasses
F
In metallurgy a ferrous alloy with a minimum of 10%
chromium content. The name originates from the fact that it
does not stain, corrode or rust as easily as ordinary steel.
This material is also called corrosion resistant steel when it
is not detailed exactly to its alloy type and grade,
particularly in the aviation industry.
7. Toxicity
G
Loss of an electron by a molecule, atom or ion
8. Stainless
steel
H
also known as arc flash, welder's flash, corneal flash
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.
9. Arc eye
I
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.
10. Voltage
J
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.
