Question

for work angles, 0 degrees begins on which letters?

a
b
c
d

Explanation:

Identify the reference lines for work angles

Using the Welding Work Angle knowledge point

• The work angle is the angle of the electrode relative to the surface of the base metal.
• For a groove weld (left), the reference line perpendicular to the base plate is labeled A, representing \(0^\circ\).
• For a fillet weld in a T-joint (right), the reference line perpendicular to the vertical member is labeled C, representing \(0^\circ\).

Determine the starting letters

Using the Welding Work Angle knowledge point

• The \(0^\circ\) reference positions from which the work angles are measured correspond to the dashed lines labeled A and C.

Answer:

• A
• B
• C (Correct answer)
• D
