Active Exploration of Weld Distortion Scenarios on Digital Twin

Michael Fernandez, Applus SKC.

Presented At: 
CanWeld Conference 2019

The familiar CSA W59 (or equivalent AWS D1.1) reference standard for welded structures commits contractors for submitting an effective distortion control plan where welds shall be made in sequence such as to minimize distortion and welding heat shall be balanced. These are all requirements, but standard presents no solutions on how to achieve them. Typically, plans to control weld distortion are therefore mostly intuitive with welding engineers relying on their experience combined with the results of a limited number of practical tests.
