Location of notch as per UG-84(g) for impact test specimen
Location of notch as per UG-84(g) for impact test specimen
(OP)
Dear respected experts of this forum.
I would like to get some insight regarding UG-84(g) of ASME Section VIII Division 1.
The words "normal to the surface" for the location of the notch confuses me. Could you please advice which is the correct location of the notch as per uploaded image?

Thanks in advance.

please study the attached illustration

The Charpy samples in the figure posted by lslcpfcc are in orientation B in the OPs sketch.
The 'width' of the sample is to be the thickness of the weld.

I have found a picture on ASME Section II Part C as shown, I guess this should be the correct orientation.
As per UG-84(g)
"Each set of weld metal impact specimens shall be
taken across the weld with the notch in the weld metal.
Each specimen shall be oriented so that the notch is normal
to the surface of the material and one face of the specimen
shall be within 1/16 in. (1.5 mm) of the surface of the
material"
My understanding is that "normal to the surface of material" means perpendicular to the outside surface of the material. The posted picture tells otherwise.

Notch is in the weld, and the direction of the notch is at a right angel to the surface of the original material.
