Ag Mech 2 5.02

Front

What happens if the amperage setting is too low during welding?

Back

It will cause a low and porous bead.

Front

What should you do if an electrode sticks to the metal while welding?

Back

Decrease amperage.

Front

What is the first step in preparing metal for welding?

Back

The metal should be cleaned.

Front

What is a common cause of porosity in a weld bead?

Back

Contaminated base metal.

Front

What is the effect of traveling too fast while welding?

Back

The welded bead will be too narrow.

Front

Define 'amperage' in the context of welding.

Back

Amperage refers to the amount of electric current flowing through the welding circuit.

Front

What is the purpose of cleaning metal before welding?

Back

To remove contaminants that can cause defects in the weld.

Front

What does a high travel speed in welding typically result in?

Back

It can lead to a narrow weld bead.

Front

What is the role of the electrode in welding?

Back

The electrode conducts current and provides filler material for the weld.

Front

What is porosity in welding?

Back

Porosity refers to the presence of small holes or voids in the weld bead, often caused by trapped gases.
