Ag Mech 1 Unit 5.00

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

• ball-peen hammer

• chipping hammer

• torch lighter

• wood chisel

What wire welder is used in industry as an automatic welder?

• AC/DC SMAW

• MIG

• Oxyacetylene

• TIG

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

• Arc Wedler

• Drills and Bolts

• Glue Gun

• Torch Lighter

What type of welder is best for welding thin steel?

• AC

• DC

• MIG

• TIG

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

• E6010 & E7028

• E6011 and E6013.

• E6020 and E7020.

• E6022 and E6027.

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.

• Glass

• Metal

• Wood

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

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

• electrode flux

• safety glasses

• welding gloves

• welding helmet

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