Ag Mechanics I 5.01- Welding Principles

What wire welder is used in industry as an automatic welder

• AC/DC SMAW

• MIG

• oxyacetylene

• TIG

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

What type of electrode is MOST commonly used when welding farm projects

• E6011

• E6041

• E7084

• E8015

What type of welder is BEST for welding thin steel?

• AC

• DC

• MIG

• TIG

The TIG (tungsten inert gas) welding process uses a non-consumable electrode and

• calcium or lime

• carbon dioxide

• helium or argon

• nitrogen

The two MOST commonly used general-purpose electrodes for welding projects

• E 6010 and E7028

• E6011 and E6013

• E6020 and E7020

• E6022 and E6027

An electric arc welder is used to weld

• fiberglass

• glass

• metal

• wood

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

• arc welding

• drills and bolts

• glue guns

• torch lighters

An ADVANTAGE of a DC welder is that it

• can be used without regular power line electricity

• is less expensive that an AC welder

• operates more quietly than an AC welder

• requires regular power line electricity
