Q

If a welding fabrication becomes unacceptably distorted, what means of distortion correction should be avoided?

🔍 Key Concepts

• Effects of excessive heat on metal properties during flame straightening • Difference between mechanical straightening and thermal straightening • When cutting and rewelding is preferable versus when heat shrinking can damage the structure

💭 Think About

• Which correction method adds even more localized heat to an already distorted weld area, and what can that do to metal strength and alignment? • Which methods allow you to fully re‑prepare and control the joint versus trying to ‘fight’ distortion in place? • In ship and structural work, which straightening method is usually restricted to trained specialists because of the risk of over‑heating and metallurgical damage?

✅ Before You Answer

• Identify which choice relies on localized high‑temperature heating to pull metal back into line. • Consider which methods allow for proper joint preparation and controlled rewelding instead of forcing material with heat. • Think about classification society/yard practices: which method typically has tight limitations or requires special approval/training due to risk of cracking or loss of strength?
