Quantity of Required Impacts per B31.3

[iam42]

How many impact tests are required per B31.3. the PQR is multi-process - TIG,FCAW and SAW. Do I need to do impacts for each process or do I just need to do Weld Metal and HAZ.

Thanks

If you are42, review B31.3 Table 322.2.2. and Table 323.3.1. You will find answers to your questions.

metengr,

I have read and re-read table 323.3.1. Note (3) from this Table states that three specimens from the weld metal and three from the HAZ are all that is required. I do not see any mention of taking Impacts from each welding process.

I am interpreting this as only two sets of Impacts are required. Am I reading this correctly?

Thanks

I would qualify the WPS in accordance with ASME Section IX requirements and read Note 2 in Table 322.2.2.

Metengr,

Do you mean Table 323.2.2. I cannot find Table 322.2.2

Thanks
