What does PMI tell you about filler metal?
The purpose of PMI is to verify you received the filler metal you ordered and no one in the supply chain made a mistake. A review of the filler metal specification will tell you whether the chemistry listed is the chemistry of the raw filler metal or the deposited weld metal. When checking FM for GTAW the chemistry may be of the bare FM.Reference: app.aws.org/forum/topic_show.pl?tid=31833See all results for this questionWelding & Welding Inspection - LinkedInJan 23, 2018 · Positive Material Identification (PMI) is one of the more specialized non-destructive testing methods.
