Quality impact due to shield gas purity for welding
Quality impact due to shield gas purity for welding
(OP)
Refer to ASME II SFA 5.32, minimum argon purity is 99.997%.
- What are the quality impacts in case of use lower purity (99.9% or 99.95%)?
- Please advise me about some technical references for the subject.
Thanks in advance...

I intend to use filler metal SFA 5.18, should I use minimum gas purity 99.997% per SFA 5.32? Is it mandatory requirement?
Some experienced personnel in my company comment that the requirement of SFA 5.32 is not practical in the oil and gas industries.
