Ag Mech 2 - 4.03 (Part 2)

In oxyacetylene welding, the width of the puddle formed is determined by the:

• motion of the tip and penetration.

• thickness of the welding rod.

• thickness of the metal.

• size of the tip.

When tempering a piece of metal, the student should:

• dip that portion of the metal into water and move the metal with a circular motion.

• drop the entire piece of metal into a bucket of cold water for one minute.

• bury the metal in the ground overnight.

• heat the metal with a grinder.

When one transports oxygen and acetylene tanks, they should be:

• capped and chained upright.

• uncapped and secured upright.

• capped and chained horizontally.

• uncapped and secured horizontally.

The safest way to light an oxyacetylene torch is with a:

• match.

• torch lighter.

• burning torch.

• cigarette lighter.

If Patrick sharpens his chisel and quenches it too soon, the most likely result is the chisel will:

• be even stronger.

• become soft over time.

• bend out of shape.

• shatter and crack.

When cutting carbon steel, one should hold the cutting tip:

• at 20 degrees.

• at 90 degrees.

• upside down.

• straight.

How should checking for a leak on an oxyfuel outfit be done?

• by using a cigarette lighter

• by using soapy water

• by using lighter fluid

• by using a match

What does Juan do to blow metal away from the cut he makes with the oxyacetylene torch?

• close the acetylene torch valve

• close the oxygen torch valve

• depress the oxygen torch lever

• open the oxyacetylene regulator valve

In brazing with the oxyacetylene torch, one should use a/an:

• oxidizing flame.

• one-half flame.

• neutral flame.

• tall flame.

When cutting with an oxyacetylene unit, one knows the cut is correct if:

• the top edge is square and the drag lines are slightly curved.

• the top edge is rough and the cut lines are smooth.

• the drag lines are at a 45-degree angle.

• the surface has carbon deposits on it.
