Question

Where should the welding arc be directed to ensure acceptable fusion in a bevel groove weld in a T-joint as shown in the illustration?

a. Center of the bevel
b. Root of the joint
c. Outer edges of the joint
d. Top of the bevel

Answer 1

The welding arc should be directed toward the root of the joint in a bevel groove weld on a T-joint to ensure proper fusion and weld strength.

Step-by-step explanation:

When welding a T-joint with a bevel groove, it is essential to direct the welding arc toward the root of the joint to ensure acceptable fusion. This is because the root is the point where the two pieces of metal come together at the base of the bevel, and directing the heat here ensures that the weld penetrates through the thickness of the materials being joined. Achieving proper fusion at the root is critical for the strength and integrity of the weld.
