Hi Bro,
Please help to clarify these question

Subject: ASME B31.3-2004, Table 323.2.2, A-4(b), Impact Testing of Weld Metal and Heat Affected Zone for Austenite stainless steel: “Weld metal deposits shall be impact tested in accordance with para. 323.3 if min design temp. <29oC except provide in para. 323.2.2 and in note 3 and note 6”

Question: Three exceptions for impact testing of weld metal deposits in austenitic stainless steel is that?
• First: Note 3
• Second: Note 6
• Third: Paragraph 323.2.2 (f)

And

Question: If one or more of the three exceptions for impact testing of weld metal deposits in austenitic stainless steel, as stated in clause A-4(b) of Table 323.2.2, are satisfied, is impact testing of the weld metal and HAZ required for cases where the design minimum temperature is below -29°C (-200P)?
