Welding process
Thread Content
Could the experts please help me answer this: Can the welding process for S32168+Q345R/S32168 be replaced by the two welding process evaluations for S32168/Q345 and S32168/S32168?
It depends on whether the laminated structure is considered part of the strength factor; if it isn’t, a Q345R butt joint combined with a stainless steel butt joint can be used as an alternative. (I did it this way, and the Special Inspection Agency raised no issues either)
I didn’t understand what you meant by your question !
There are reasons to suspect that a S32168 fitting was inserted after drilling holes in a Q345R/S32168 composite plate; it’s related to those two weld evaluations – I spent the whole afternoon guessing!
