Forging terminology to ASTM A694
Forging terminology to ASTM A694
(OP)
My understanding with regard to forgings to ASTM A694 is that the material must undergo significant work, usually reduction of 4 to 1. However I find that some companies certify to ASTM A694, material such as seamless pipe (API 5L X52) that has been hot worked to form fittings such as equal tees. Is it valid to certify this as a forging to ASTM A694?

What code or standard are you working under? Welding that is performed to ASME B31.4 will require a separate WPQR for material not listed. The API 5L Grades are listed, but the A 694 and A 860 material specifications are not listed. This is probably the reason why your clients need to qualify a separate WPS for these specifications.

Don't confuse spec and alloy grade with each other.

Depending on application, such as impact testing, yes you can be required to qualify a weld procedure for similar grades of material under different material specifications.
