Resources on Welding Distortion, Causes and Prevention (16)

Basic information on Welding Distortion, Causes and Prevention can be found in our page on Welding Distortion.

This 16th Mid Month Bulletin deals with Welding Distortion. The importance of this subject is due to its considerable negative economic impact. Distortion affects schedules causing unexpected delays and increases costs by involving additional fitting and welding operations.

Large organizations like the US Navy and major Shipyards have invested remarkably, in time, money and efforts, to foster research and studies intended to mitigate the effects of distortion, with incremental progress towards improved results.

Information on Causes and Prevention of Welding Distortion can be found by clicking on the links to the following sources:
