Buttering welding
Buttering welding
(OP)
Gentleman
We're fabricating the pressure vessel. But due to short length(approx. 5~6mm) of plate with width of 1,000mm, we're planning to do buttering welding at joint to recover the gap.
Is it possible and allowable way? Relevant PQT will be performed and witnessed by Authorized Inspector.
Base material is P355 NL1 and Electrode is E7018-1. PWHT required

RE: Buttering welding
However, have all other venues been investigated and discarded, like fabrication tolerances, maximum welding gap, etc. After all, you are talking a measly 5-6 mm gap for bridging...
