RE: [MW:23086] Re: Crack in Duplex S.S material

What grade of duplex are you welding?

Lean or Super governs the amount of heat input allowed.

What welding process are you using? What shielding gas are you using?

Dear Abhishek,

 

Maybe you should check the whole welding process whether is corrdance with WPS . And you can do some basic test for the failure part, such as ferrite content.

To confirm root cause, then identify which welding process generate impact.

 

Thanks

Leon
