Prequalified Welds
Prequalified Welds
(OP)
Ok, I hear the phrase "prequalified welds" and understand that the typical welds most engineers regularly specify fall under this category. These are welds that have performed well historically and fall under a precisely defined procedure of execution.
However, I curious if any structural engineers on this board have had to deal with welds that were not prequalified. What was the specific instance and how was it handled??
Any general insight on this topic would be greatly appreciated...

Take a look through the prequalified joint procedures and pay attention to thickness limitations, process limitations, and configurations that might give you problems. Tubular structures with T,K,Y joints and some very thick sections can lead to issues as well.
