If you will follow the criteria from Section 4 and prove all of the elements work to produce a quality weldment then there should be no problem.

You might consider AWS D9.1-Sheet Metal Welding Code. It may be just right for your coated steels and GMAW process with the listed base metal thickness.

I believe what you are actually performing is braze welding and not a true weld.

If these are sheet steel - structural members, you may have a tough time trying to convince the local building dept. or your RDP. This is by definition a brazed joint. All the building codes I have worked with (UBC/IBC/CBC) specifically address "welding processes", not brazing.

If you are melting the base metal, you are combining cold formed structural steel with the ERCUSi-A (a copper based alloy) filler metal. This cannot be good and good luck trying to pass any mechanical testing.

My interpretation of the D1.3-98 code is your filler metal would not be appropriate for the application.

Are you trying to qualify a proprietary connection for approval by an accrediting body such as NES, ICBO-ES, etc?

rsliker:
It depends on what market your company is trying to impact.

It does not mean your connection cannot be qualified, it does mean you have much more "splaining" to do in the form of research, test data, criteria, etc. before getting any type of approval due to that filler metal alloy and base metal combination.

If you intend to go beyond most of the smaller local jurisdictions (national/global), you will have to shell out some $$ as well. You not only have to pay for testing and the proof of testing, you also have to pay for review and application fees and any additional testing required by the reviewing body.

Good luck in your quest.
