What are the methods used to minimize distortion?

General rules for preventing distortion are: keep the weld (fillet) to the minimum specified size. use balanced welding about the neutral axis. keep the time between runs to a minimum.

What are the techniques that can be used to reduce distortion warping in fusion welding?

Using a water-cooled jig is an effective tool in minimizing distortion in sheet metal welding. The tool carries heat away from the welded components and circulates water through the tubes during welding. Clamps are also used in this process to minimize the distortion.

How do you prevent angular distortion?

Angular distortion can be controlled by following: Using the minimum amount of weld-metal required. Depositing the weld-metal in the fewest number of layers. Avoiding very narrow root profiles and wide faces as much as possible.
