What do you guys think of this weld

[Sonora Iron]

6010 root, 7018 fill and cap most likely.

Could easily be ER-70S2 or S6 couldn’t it?

6010 that's what some of those pipe liners use for the root ( Gas and oil lines) . In the plants we use tig roots for most pipe. So yes ER-70 or ER-80
for A-106 pipe
