Weld Macro examination
pavainathan
I've a question about Macro examination in
PQR's. What is the minimum magnifcation level we need to have? ,is
there any reference standard/specification .
One of my client spec syas it must be x5 .I have come across with
various PQR review this magnification level is varying a range from
x2.7 ,x3.4,x4.0&x5.0.
Also is there any significance in referring the letter in small
case(x5) or Caps(X5)
Any one can put your expertise in this regard.

If you design, construction and testing code is the BPVC of ASME then:
stud welds: x10
tube to tube sheet welds: x10 to 20x
resistance welding: x10
laser beam welding: x25
flush welding: x5
hard facing: x5

Hi
Macro examination is mostly carried out at 5X to 10X magnification to assess the internal weld quality.
The magnification will depend upon your client specs. / applicable code.
If your PQR is as per ASME Sec.IX, then please refer following clause:
QW-453, Note 8.
QW-453: PROCEDURE/PERFORMANCE QUALIFICATION THICKNESS LIMITS AND TEST
SPECIMENS FOR HARD-FACING (WEAR-RESISTANT) AND CORROSIONRESISTANT
OVERLAYS
Notes(8): The base metal shall be sectioned transversely to the direction of the hard-facing overlay. The two faces of the hard-facing exposed by sectioning shall be polished and etched with a suitable etchant and shall be visually examined with ×5 magnification for cracks in the base metal or the heat affected zone, lack of fusion, or other linear defects.
Regards

You are not going to like this reply! As with most questions, you must
first spell out what Code you are trying to comply with and then what
type of weld.
Consider ASME Section IX, the following apply:
- For stud welding, QW-192.1.4, examination at 10X
- For tube-to-tube sheet welding, QW-193.1.3, examination 10X to 20X
- For laser beam welding, QW-197.1, minimum 25X
- For flash welding, QW-199.1.3, examination at 5X
God knows what the ISO/EN/BS specs require - it's a thread I prefer not
to try and unravel unless I absolutely must.
Regard the issue of upper case, X, or lower case, x, there is no
difference - just a personal preference - in this usage the x only means
"times".
Hope this helps.

" The Eye is our most valuable inspection instrument.An Examination
with the naked eye or with a lens at a low magnification (Ex : x5)
comprises what is meant by Macro Examination" - The Metallographic
Examination of Metals - J L Taylor
dont worry about the x or X .... this is to denote vision 'multiplied
by ' / 'times' . I have usually noticed 'x' though .

| 10x (also read 10X) is the limit for macro; the in-between magnification level choice is dependent on many factors related to the application, usually decided by the design engineer. --- On Wed, 10/11/10, pavainathan <pavai...@gmail.com> wrote: |

Dear All, can any one give information on type of PAINT which we can use on the fit up joints before welding so that it will prevent the rusting of the surface of fit up joints. Kindly give us the name and type and brand of the paint which will be faster to get the same Shamesh Lotlikar |

Dear Mr. Bilal,
Yes you are correct.
As per ASME Sec-IX, the Macro size of 10X to 20X is defined only for Tube to tube sheet welding.
But since the Macro picture will be too large for the Page to be printed, we get the photos of lesser magnification.
Thanking you,
Best regards,

I asked some training agent (AWS Authorized) regarding AWS-CWEng training & Exam, but no response from them ,so i think that they are not conducting training & Exam for AWS-CWEng.
but if we have more than 20 candidate than ,we can arrange training & Examination in India through Qualiy control Egypt.
