Depending on what welding code you are working to, certain welding procedures will require, mechanical or a metallurgical assessment to demonstrate the integrity of the proposed welding procedure.
Pre-Qualified welding procedures are derived from the combination of essential variables that have been shown to produce sound structural welds.
Each enquiry will be handled by a qualified Welding Inspector and we will advise you whether you need a Pre-Qualified Procedure or a Qualified Procedure.
Either way, if its not in our database, we will advise you on how long it would take us to get one to you.
