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 molten.

"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.

"TIG 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."
