Cracking Issue happens. However I have never experienced a single
issue using the product I recommended. On the other hand those Cheap
flat rods/sticks that you can get in you local tractor supply that say
silver braze are a complete JOKE and nothing but trouble. I called
the company that makes these so called Silver rods and they admit that
they are only at best 1/2% silver. The product that I use is Cadmium
as well as lead free and flows like water even in tight joints. If
you make the jump to the more expensive 56% stuff you get the USDA and
use for Dairy approval. I have never had a cracking issue on any of
the metals I have used it on. Welding Stainless is not without
problems either. Correct shielding gas, Purging the inside of the
tube and correct filler material are all necessary to do the job
correctly to avoid cracking and crystallization. I assume you paid
someone to weld your rig. I am not willing to take that chance in
these parts. Your argument has merit but I have welded professionally
for many years and can say without doubt that DONE RIGHT (huge
variable) brazing in most cases is just as good or better than a weld.
