Welder Code Qualifications
Welder Code Qualifications
(OP)
Can someone refer me to the welders qualification code. I am researching if welding to a vertical pressure vessel support leg requires special qualification, procedure and inspection if the portion of the leg is not contacting or within some predetermined length from the pressure components. Are the legs considered part of the pressure welding code zone? Can you weld to legs without an alteration or rerating?
Thanks,

Now, should you have a qualified welding procedure, welder, and NDT for weld repair of the support leg? ABSOLUTELY.

Since you are welding a non-pressure part material to an existing non-pressure part material, this falls outside of Section VIII construction code.

I feel like that most of the time.
Back to your question tho, you do not need any special code of construction or repair code to add X-bracing to supports.
However the additional bracing should be considered in calcs and the welder should be currently qualified as per Sec IX.
Assuming the pv is located at a mill or plantsite, that entity would have jurisdiction and most mill have their own welding standards.
Hope this helps,
