How to straighten sheet metal after welding.

Heat straightening does not symmetrically straighten the metal and is a gradual process. Roger cook explaining how he uses hot and cold to tighten the steel plate to remove heat deformations. Working with sheel metal. The yield stress point is defined as the stress at which a material begins to deform plastically.

When you weld after it cools there is always some shrinkage never expansion. Body files are usually used after another age old process has been used to straighten or shrink sheetmetal. Maybe even make the brace slightly big. Heat straightening involves applying controlled heat to a deformed part of steel in heating and cooling cycles until the metal gradually straightens.

Fabricators straighten metal using many methods including heat straightening. Then weld on the other plates that you have laid out in marker. When performing hot mechanical straightening heat the metal to the yield stress point. If it did pull in then cut a brace or jack it open to push the sides apart to where they should be.

Heating to this temperature pushes the metal past the yield stress point and allows you to straighten the metal. It started as an art heat straightening began in the early days of welding with the earliest written information dating back to 1938.
