Explain how metal becomes distorted during the welding process.
What will be an ideal response?
Anytime metal is heated in a localized zone or spot it expands in that area and, after the metal cools, it is no longer straight or flat. If a piece of metal is cut, there will be localized heating along the edge of the cut, and, unless special care is taken, the part will not be usable as a result of its distortion. This distortion is a much greater problem with thin metals. By using a plasma cutter, an auto body worker can cut the thin, low-alloy sheet metal of a damaged car with little problem from distortion.
