[MW:1471] Re: radiography of aluminium

Dear Friends,

 

 

Kindly let me know from which website or blogspot the fabrication tolerances for Pressure Parts and Structural Items can  free downloads be available.

 

The matter is urgent.

 

 

Regards,

Hello Muhammed,

 

In response to your question below, X-ray radiography is you best choice due to quality issues. 

 

The second question is slightly difficult to answer as each tube/generator has different characteristics, as also the film and geometric variables have.  In referencing one of my resources, a higher end X-ray tube rated at 400-450 kV could theoretically penetrate thickness up to roughly 300 mm.  The lower limit for 50 kV is approximately 20 mm.

 

I usually work with castings from 30 mm to approximately 75 mm, although, I primarily use digital radiography using a CMOS detector. 

 

A generally accepted method of ensuring acceptability of a method is to demonstrate required sensitivity (i.e. hole-type or wire-type image quality indicators) per referencing code. 

 

I have a colleague that is better accquainted with thinner materials.  I will forward him your question and I will email you if I can clarify practical limits.

Thank you,

Charles Nelson

Hi friends,

 

Good morning,

 

I have a query regarding the radiography of aluminium.

 

X-ray or gamma ray is better for aluminium?

 

If x ray is better , what is the thickness range it can be done?

 

If gamma ray is better , what is the thickness range it can be done?
 

If anybody having the procedure, please forward

Thanks & Regards
Muhammed Ibrahim PK
