Hello everybody!
Just wanted to ask you if the Sargol and Sarlun terms are widely used and commonly known in the US. In my previous thread I asked about a lip weld.
The Sargol and Sarlun turned out to be just what I was asking about (or similar to that). It turned out that "the lip weld" is out of the AWS terminology. But the description of the Sargol and Sarlun facings use the term "lip":
"The Sargol and Sarlun facings, which have lips for seal welding, are used frequently for severe service conditions."

So, plase, tell me if the terms Sargol and Sarlun are common and widely acceptable.
Thank you.

This is what our guys call a "lip weld":

(Well, I'm from Russia.)
