Here's a possible answer:
"There are three types
of arc welds. Arc means that an electrical current is being used to produce
heat for the weld. In each process, it's necessary to have an electrode, which
acts as a conductor for a hot, electric arc to flow from the electrical source
to the piece being welded.
"STICK welding is the first kind of weld.
In this process, the flux melts over the weld as the electrode is consumed
and deposited during the welding operation. A flux is something that is used
to coat or cover the weld to prevent air from mixing with it while it is still
"MIG is the second type of arc weld. In this process, a thin
wire that comes off a spool is used as the electrode, and is consumed and
deposited during the welding operation. Argon gas is used as a shield in this
operation. A shield is similar to a flux except that gas is used to cover
the weld to prevent air from mixing with it while it is still molten.
is the third type of weld. In this process, the electrode (made out of tungsten)
that is conducting the electrical charge isn't melted and deposited on the
weld. In TIG welding, the filler is a plain piece of metal added drop by drop
to the weld."
As a welder, you'll have to be able to
explain what you do to others.
"They're very, very important (communication
skills)," says welder Kim Buchan. "Because when you're giving somebody a job,
not just as a foreman but as another welder, you want to be able to communicate
what you're looking for."
