The two most commonly used general-purpose electrodes for welding projects are:

• E6010 and E7028

• E6011 and E6013

• E6020 and E7020

• E6022 and E6027

The proper tool for removing slag from a weld is a:

• ball-peen hammer.

• chipping hammer.

• torch lighter.

• wood chisel.

What welder produces a weld that is stronger and freer of corrosion than that of other welders when welding stainless steel or aluminum?

• AC SMAW

• DC reverse polarity SMAW

• DC straight polarity SMAW

• TIG

When welding a metal project without electrical power available, what type of arc welder should be used?

• AC (alternating current)

• AC/DC

• DC (direct current)

• oxyacetylene

What is used to protect the eyes of a welder from the light rays?

• electrode flux

• safety glasses

• welding gloves

• welding helmet

What type of electrode is most commonly used when welding farm projects?

• E6011

• E6041

• E7084

• E8015

Constructing and repairing steel farm equipment by melting and joining the edges of metal pieces are done by using:

• arc welders.

• drills and bolts.

• glue guns.

• torch lighters.

An electric arc welder is used to weld:

• fiberglass

• glass

• metal

• wood

The TIG (tungsten inert gas) welding process uses a nonconsumable electrode and:

• calcium or lime.

• carbon dioxide.

• helium or argon.

• nitrogen.

An advantage of a DC welder is that it:

• can be used without regular power line electricity.

• is less expensive than an AC welder.

• operates more quietly than an AC welder.

• requires regular power line electricity.
