Kix,
I guess my view of this is- if the manufacturer indeed states that it is weldable and they instruct how to do it, if a failure were to occur, they would be responsible. Do you have a link to the tech. data forms you refer to?
I ask this because, it may be in the fine print somewhere, a disclaimer. People will tell us all kinds of things to get us to use their product, but will not put it in writing, and if they do put it in writing, in the fine print is their back door.
I am not saying this is the case, but I would sure want to have hard documentation that I could use to CYA in the event of a problem.
BTW I am not trying to be obtuse, I am just a detail guy who does not like to get caught with my pants down. So this indeed is an educational session for me regardless. Thanks for spending the time to bring me up to speed, it is greatly appreciated. :-)
5.10 Preparation of Base Metal
Surfaces on which weld metal is to be deposited
shall be smooth, uniform, and free from fins, tears,
cracks, and other discontinuities that would
adversely affect the quality or strength of the weld.
Surfaces to be welded, and surfaces adjacent to a
weld, shall also be free from loose or thick scale,
slag, rust, moisture, grease, and other foreign
material that would prevent proper welding or
produce objectionable fumes.
