Just wondering how the quality of an old braze compares to a mig. This restoration job I have has a few pieces of metal replaced that have been brazed, I forget what it is exactly…it’s a copper kinda color. The metal looks good and so does the braze, I’m just wondering if it’s ok to leave as is, anything I should know?

I’m just a bit concerned as one of the guys say’s he recalled a lot of paint lifting problems over these kinds of brazes when they were common. It was before my time. here’s a pi btw:

If I remember correctly, what caused problems with the repair not holding was when the flux was not cleaned off good enough. I usually just sandblasted everything with a handheld blaster to clean the joint , and give it some tooth.
I concur with everybody else. The weld held this long. leave it alone, clean it (sandblast) and go on. Looks like the rest of the top of that fender could use a quick blasting anyway.
I’ve done a bit of brazing in my past without any failures.
But in my AirForce Repair manuals they make it very clear that just like with Aluminum, give it enough stress, and or enough time, and it will in no doubt fail.But that could be decades if not longer.
Personally, that looks like it would suck to reproduce. and there is no clean way to fix it. So I’d say leave er’ as is. - AuthorPosts
