Question

What technique is employed with (PAW) to produce full penetration welds without a bevel edge preparation?

A) Backing gas shielding
B) Arc voltage adjustment
C) Keyhole welding
D) Filler metal selection

Answer 1

Keyhole welding is the technique employed with (PAW) to produce full penetration welds without a bevel edge preparation.

Step-by-step explanation:

The technique employed with (PAW) to produce full penetration welds without a bevel edge preparation is Keyhole welding. Keyhole welding is a process in which a laser or an arc creates a keyhole-shaped cavity in the workpiece. This keyhole allows for deep penetration and joining of the metal without the need for a bevel edge preparation.
