Re: Re: [MW:13582] Ultrasonic Testing & Intergranular Corrosion Testing; G28 Method A for CRO Welding on Carbon Steel with Inconel 625

Hi,

Generally not required, but if Client insist to do so and pay for extra cost then go for it.

But performing these tests may be useful in future if ever encounter a client requesting the
same, in that case you might have to carry out new qualification, i have seen major
manufacturers doing these tests just to make sure that they do not re-qualify if ever client
request UT,Intergranular corrosion test..

What I am confusing is that Intergranular Corrosion (G28 Method A) and Ultrasonic Test is
applicable to conduct or not?
