Which method helps prevent misalignment in TIG weld joints?

• A. Fixtures and clamps
• B. Increase travel speed
• C. Use smaller torch
• D. Use lower shielding gas flow

Answer: (A)

Keeping parts in the exact position during welding is essential to prevent misalignment. Fixtures and clamps hold the workpieces rigidly, maintain the correct fit-up and gap, and resist movement from the weld heat and torch forces. This positional stability is crucial in TIG welding because the root and subsequent passes rely on precise alignment for a consistent, clean weld along the joint.

Increasing travel speed changes heat input and can reduce distortion, but it doesn’t lock the parts in place to stop shifting. A smaller torch might help access tight areas, but it doesn’t address joint stability. Lower shielding gas flow affects the weld environment, not the alignment of the workpieces.
