5.0 Ag Mechanics I

Neil is making a welded metal project. Before he starts welding, what should he do to the metal?

• brush and oil

• grind and paint

• identify and clean

• wash with solvent

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

• ball-peen hammer

• chipping hammer

• torch lighter

• wood chisel

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

• calcium or lime

• carbon dioxide

• helium or argon

• nitrogen

An amperage setting that is too low will cause a:

• high and narrow bead

• low and porous bead

• perfect bead

• weld with spattered edges

What type of welder is best for welding thin steel?

• AC

• DC

• MIG

• TIG

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

When metal is prepared for welding, it should be:

• cleaned

• oiled

• painted

• weighed

Metal thickness, electrode size, and welding position are used to decide the

• brand of welder

• employee's salary

• voltage setting

• amperage setting

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

• AC

• AC/DC

• DC

• oxyactylene

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
