How to remove warping in aluminum sheet metal.

Weld along the neutral axis. To anneal work hardened aluminum coat the panel with the soot from a smoking acetylene torch flame. Accordingly the aluminum will have reached the annealed temperature. So here are 11 ways to prevent sheet metal from warping in tig welding.

Join the ccrc community to access a huge library of instructional classic car restoration videos. Though weld shrinkage cannot be prevented it can be controlled by following these steps. Fix problems before they permanently set. Here s a list of tips that help reduce warpage in sheet metal fabricaitons.

Design and welding should be addressed to minimize this sort of warping. Minimize the amount of heat put into the weld. Work hot and fast a lot of damage or excessive warping when welding could be from dwelling too long in a. Preset the pieces sometimes called counter or opposing set up.

Aggressive abrasives like coal slag or aluminum oxide generates more heat and peening. Welding heat sink applying a heat sink behind the weld or on the surrounding metal of a weld will help keep the the heat from spreading and. Use clamps to control expansion. Move around on your project.

Then use a neutral flame to heat the panel and burn off the soot. Limit the number of passes. Use intermittent welds instead of continuous welds where possible to minimize the amount of weld metal. Intermittent rather than continuous welds help as does minimizing the amount of filler metal used.

Correctly sizing a weld not only minimizes distortion but also saves weld metal and time.
