What is the key difference between welding and brazing?

• Welding uses a non-melting electrode, while brazing does not.

• Welding joins metals by melting them, while brazing joins metals without melting them.

• Welding is done at lower temperatures than brazing.

• Welding requires filler metal, while brazing does not.

What is the purpose of using a non-melting electrode in gas tungsten arc welding (GTAW)?

• To produce the arc

• To add filler material

• To cool the weld area

• To clean the metal surface

What is a weld or weld bead?

• A process of cutting metal

• A fused joint of base metals

• A type of welding machine

• A protective coating on metal
