Re: [MW:12317] change in welding color in Cr Mo V steel

Hii,

Color will veries depends on Heat Input ...

But your interpretation is not a criterai for Welder
Qualification/Skill test ....There will be governing the codes as per

We need to Qualify the welders as per Code/Standards ..

And the result of Weldabilty will be depends on the Inspection/Testing
...(Not with Color)

Thank you

Suresh
