For the 2G weld, what angle is recommended to minimize distortion?

• A. 3-4 degrees
• B. 5-6 degrees
• C. 0 degrees
• D. 10 degrees

Answer: (A)

In a 2G weld, controlling distortion comes from how heat is directed and how the weld pool progresses as it cools. A small travel angle of about three to four degrees helps balance heat input along the joint and moderates the contraction that causes warping, leading to a straighter weld with less distortion. If you run with no angle, heat is applied symmetrically and distortion can be harder to manage. Too large an angle (five to six or more, or around ten) shifts heat and deposition more aggressively in one direction, which can increase residual stresses and distortion. Therefore, a gentle tilt of roughly three to four degrees provides the best balance to minimize distortion in a 2G weld.
