The mat. is EN19 Chrome with a BHN of 252, and the test had to be performed according to ASTM E587 so they had to inspection criteria required. I was convinced that the UT test was questionable, so I had it done again using a different inspection company and guess what... they got the same...

The mat. is EN19 Chrome with a BHN of 252. We turned it on a manual lathe and took off 7/16" using a carbide insert. I was convinced that the UT test was questionable, so I had it done again using a different inspection company and guess what... they got the same results stating that the bar...

Hi, I had a 6" round Bar UT inspected for cracks and the results came back as "flawless" and acceptable for use. Yet after machining off 1/2" from the OD using a manual lathe, we found numerous hair line cracks. When we confronted the inspection company they implied that the test was done...

God day All, I had a 6" round Bar UT inspected for cracks and the results came back as "flawless" and acceptable for use. Yet after machining off 1/2" from the OD using a manual lathe, we found numerous hair line cracks. When we confronted the inspection company they implied that the test was...

Thank a lot, appeciate the help guys.

Thanks, we looked into that but the overall lenght (65ft.) was the problem.

Scholars, I have a 30" Riser with a 300 series Flange at one end, basically it comprises of two lenghts of casing welded at the middle. The overall lenght being 65ft.The Riser appears to be bent somewhere along it's lenght. We've pulled a line (from the flange end) parallel to the riser down to...

both materials are 4130 @ a 30" diameter.

We have a 3/4" float shoe to be joined to a casing that's either 1" or 1.5" thick. The O.D are both 30" but I'm concearned about the difference that would occur in the I.D at the welded area.

That's the interesting part of this whole scinario. I have a WPS for the 4130 and another for the inconel-625 but the Customer wants one procedure to cover both materials. Funny huh.

Thanks for responding guys, I really appreciate it, I see I still have a lot to learn. I intended to use Nickel-Chromium-Molybdenum low iron bare welding wire as the filler. Any other advise?

My guys intend to (Argon weld) 4130 onto Inconel-625, I know that post weld heat treatment isn't required but I need confirmation that pre weld HT isn't required for the 4130. I don't think its required, am I wrong?
