what software do u simulate welding construction and welding

Hi Edisonwang,
I use Weld_IT for quick and dirty calcs. On complex geometries, I'll get the FEA guys to use (UG)NX-FEA. Ansys was removed a few years ago from their workstations. You should be able to model the weld and assign it it's own allowable stress.

You mentioned "set the welding parameter". Are you talking about specifying the heat input? Are you interested in predicting distortion?

yes i want to know what will occur when the weld joint formed by weld metal and base material in different matching and differnt heat input suffered force . of course it will involve stress and distortion.

The Edison Welding Institute (EWI) developed their own software.

http://ewi.org/ewi-weldpredictor-innovation-in-modeling-simulation/

"...With each calculation, you get a virtual prediction of the resulting microstructure, thermal profiles, residual stress, and distortion for plate and pipe welding – all without performing extensive designs of experiment.
The latest version of EWI WeldPredictor allows for more weld joint configurations, dissimilar materials combinations, user-defined weld bead shape, and the abilities to apply thermal-mechanical conditions and predict specific time-temperature history."

I've seen a demonstration of it during the development phase in its infancy. It looked like it had huge potential at the time.

thanks ,but if the simulate software is more popular,it depends on two things ,first is huge training material of it ,second is easy to use.
hope the EWI solve them
