For aluminum, local heat treatment is to be applied to the area of the plate that is required to be
straightened, followed by standard panel beating of that area.
If the distortion of either steel or aluminum components is too severe to be beaten out, it is

(fig. 2-2) applies to a severely distorted plate and should be interpreted appropriately for less
